Fun with Characters
Complete the checkCharacter() method which has 2 parameters: A String, and a specified index (int). The method checks the character at the specified index of the String parameter and returns a String based on the type of character at that location indicating if the character is a letter, digit, whitespace, or unknown character.
Ex: The method calls below with the given arguments will return the following Strings:
checkCharacter("happy birthday", 2) returns "Character 'p' is a letter"
checkCharacter("happy birthday", 5) returns "Character ' ' is a white space"
checkCharacter("happy birthday 2 you", 15) returns "Character '2' is a digit"
checkCharacter("happy birthday!", 14) returns "Character '!' is unknown"
CODE:
public class LabProgram {
public static String checkCharacter(String inputString, int index){
/* Type your code here. */
}
public static void main(String[] args) {
System.out.println(checkCharacter("happy birthday", 2));
System.out.println(checkCharacter("happy birthday", 5));
System.out.println(checkCharacter("happy birthday 2 you", 15));
System.out.println(checkCharacter("happy birthday!", 14));
}
}
The program is an illustration of conditional statements.
Conditional statements are statements whose execution is dependent on the truth value of the condition.
The checkCharacter() method in Java, where comments are used to explain each line is as follows:
//This defines the checkCharacter() method
public static String checkCharacter(String inputString, int index){
//This checks if the character at the index, is a digit
if(Character.isDigit(inputString.charAt(index))){
//If yes, it returns "Digit"
return "Character "+inputString.charAt(index)+" is a digit";
}
//This checks if the character at the index, is a letter
else if(Character.isLetter(inputString.charAt(index))){
//If yes, it returns "letter"
return "Character "+inputString.charAt(index)+" is a Letter";
}
//This checks if the character at the index, is a white space
else if(inputString.charAt(index) ==' '){
//If yes, it returns "white space"
return "Character "+inputString.charAt(index)+" is a white space";
}
#If all the above conditions are false
else{
//If yes, it returns "unknown character"
return "Character "+inputString.charAt(index)+" is an unknown character";
}
}
The string to return depends on the character at the index.

A color image uses 16bits to represent a pixel. What is the maximum number of different colors that can be represented?
Answer: A color image uses 16 bits to represent a pixel. What is the maximum number of different colors that can be represented? With 16 bits, we can represent up to 2^16 different colors. Assume six devices are arranged in a mesh topology.
Explanation:
The terms 16-bit picture, high color image, and 32K color image are all used to describe images that have 16 bits per pixel.
What is a pixel?The smallest addressable element in a raster image or the smallest point in an all points addressable display device is known as a pixel (abbreviated as px), pel, or picture element in digital imaging.
The smallest component in most digital display systems that can be changed by software are pixels.
Photos with 16 bits per pixel are referred to as 16-bit pictures, high color images, and 32K color images.
The number of distinct colors that can be represented by 16 bits, where there are 5 bits for each of the red, green, and blue values and the 16th bit can be the alpha bit, is around 32 thousand.
Thus, the maximum number of different colors that can be represented is 32 thousand.

Program Rock.java contains a skeleton for the game Rock, Paper, Scissors. Add statements to the program as indicated by the comments so that the program asks the user to enter a play, generates a random play for the computer, compares them and announces the winner (and why). For example, one run of your program might look like this:
Enter your play: R, P, or S
r
Computer play is S
Rock crushes scissors, you win!
Note that the user should be able to enter either upper or lower case r, p, and s. Add a loop to make sure the user only enters an R, P, or S. The user's play is stored as a string to make it easy to convert whatever is entered to upper case. Use if statements to convert the randomly generated integer for the computer's play to a string.
public class Rock
{
public static void main(String[] args)
{
String personPlay; //User's play -- "R", "P", or "S"
String computerPlay; //Computer's play -- "R", "P", or "S"
int computerInt; //Randomly generated number used to determine
//computer's play
// Add the code for each action beneath the comment. // more than one line may be needed in some cases // Get player's play -- note that this is stored as a string
// Make player's play uppercase for ease of comparison
// Generate computer's play (0,1,2) – use (int) (Math.random() * 3) to
// generate a random play
// Translate computer's randomly generated play to string // using mutually exclusive conditional statements

People hardly ever play Rock, Paper, Scissors one game at a time. They play matches that are best 2 out of 3, best 3 out of 5, etc. Change your program to prompt the user for the odd number of games they want to play and use a loop to make sure it is an odd number. Then, add a loop to your program to play the game multiple times. Keep track of who wins, and make sure the loop stops when either the computer or the user has accumulated enough wins. Ties do not count in either the game total or the win totals – so a best 2 out of 3 match requires 3 games to be played where someone wins 2 times.

12.20 LAB: Driving costs - functions
Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both floats) as input, and output the gas cost for 10 miles, 50 miles, and 400 miles.
Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
print('{:.2f}'.format(your_value))
Ex: If the input is:
20.0
3.1599
the output is:
1.58
7.90
63.20
Your program must define and call the following driving_cost() function. Given input parameters driven_miles, miles_per_gallon, and dollars_per_gallon, the function returns the dollar cost to drive those miles.
Ex: If the function is called with:
50 20.0 3.1599
the function returns:
7.89975
def driving_cost(driven_miles, miles_per_gallon, dollars_per_gallon)
Your program should call the function three times to determine the gas cost for 10 miles, 50 miles, and 400 miles.
---------------------------------------------------
I need help for this part
Ex: If the function is called with:
50 20.0 3.1599
how do I get it to input the three to get the output of 7.89975?
-------------------------------------
My code:
# Define your function here.
def driving_cost(driven_miles, miles_per_gallon, dollars_per_gallon):
return (driven_miles/miles_per_gallon) * dollars_per_gallon
if __name__ == '__main__':
# Type your code here.
# Miles per gallon from input
miles_per_gallon = float(input())
#Dollars per gallon from input
dollars_per_gallon = float(input())
# Display the results as output
print('{:.2f}'.format(driving_cost(10, miles_per_gallon,dollars_per_gallon)))
print('{:.2f}'.format(driving_cost(50, miles_per_gallon,dollars_per_gallon)))
print('{:.2f}'.format(driving_cost(400, miles_per_gallon,dollars_per_gallon)))
Answer:Change your logic to:
for (int i = 0; i < 4; i++) {
System.out.println("Please input a number between zero to 3");
// use input and don't advance the scanner every time
int input = sc.nextInt();
if (input == 0) {
System.out.println("You have selected " + right);
}
if (input == 1) {
System.out.println("You have selected " + left);
}
// so on and so forth
}
By using sc.nextInt() four times, you are looking for the next token of the input which isn't there. So fetch the input for each run of the for-loop and it will work as expected.

9. In a program with 25% loads, 10% stores, 11% branches, 2% jumps, 52% R-type. The standard CPI for each instruction type is 2 cycles loads, 2 cycles stores, 1 cycle branches, 2 cycles jumps, 1 cycle R-type. The branches have a misprediction penalty of an additional 2 cycles when it misses, which happens 30% of the time. Loads create a RAW hazard 20% of the time adding in an extra cycle to the execution time. What is the average CPI for this program on this processor
Answer:
2.6
Explanation:
Given the following code, what logic would you need to include to print all even values stored within the array:
int[] myArray = {1,2,38,4,54,6,7,8,9,10};
for (int i = 0; i < myArray.length; i++) {
//your code goes here
}
NOTE: Your response should be just the missing logic--not the entire problem set.
The missing logic whigh would allow all the even numbers stored within the array to be printed is if(myArray[i]%2 == 0)
Even numbers are divisible by 2, and hence, will leave no remainder when divided by 2. Using the modulo operator, each iterated value in the array should be checked if it has a remainder of 0, when divided by 2.Hence, if the remainder is 0, then the value is even and the value should be printed.
