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.

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)))

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

Write a program that prompt the user to enter a bank balance. The balance entered by the user is read into a variable named balance. The program then prompts the user to enter the amount to be deposited. The amount entered by the user is read into a variable named deposit. The program that calculates the new balance, which is the present balance plus the deposit. The program then displays the new balance.
