Write a C++ program that promotes the user to enter 2 double values, then ask the user to enter a mathematical sign either ‘+' or ‘-‘ or ‘x' or ‘/'. Based on the input sign, the program should perform the corresponding mathematical operation and print the result.

Answers

Answer 1

Answer:

#include<iostream>

using namespace std;

int main(){

double num1, num2;

char ope;

cout<<"Enter two numbers: ";

cin>>num1>>num2;

cout<<"Enter an operator +, -, /, * :";

cin>>ope;

if(ope == '+'){

cout<<num1+num2;}

else if(ope == '-'){

cout<<num1-num2;}

else if(ope == '*'){

cout<<num1*num2;}

else if(ope == '/'){

cout<<num1/num2;}

else{

cout<<"Invalid operator";}

return 0;

}

Explanation:

#include<iostream>

using namespace std;

int main(){

This line declares num1 and num2 as double

double num1, num2;

This line declares ope as a character

char ope;

This line prompts user for user inputs

cout<<"Enter two numbers: ";

This line gets user inputs

cin>>num1>>num2;

This line prompts user for operator

cout<<"Enter an operator +, -, /, * :";

This line gets the operator

cin>>ope;

This condition checks if the operator is +. If yes, it adds and prints the result

if(ope == '+'){

cout<<num1+num2;}

This condition checks if the operator is -. If yes, it subtracts and prints the result

else if(ope == '-'){

cout<<num1-num2;}

This condition checks if the operator is *. If yes, it multiplies and prints the result

else if(ope == '*'){

cout<<num1*num2;}

This condition checks if the operator is /. If yes, it divides and prints the result

else if(ope == '/'){

cout<<num1/num2;}

This checks for invalid operators

else{

cout<<"Invalid operator";}

return 0;

}

Explanation:

the answer is a i am right

Answer:

Here are the steps I followed to create the chart on the Microsoft Excel spreadsheet.

I clicked the Insert option from the top toolbar.

I clicked the Chart option.

I clicked Chart Type, and selected the type of chart I wanted. The table above provides data on the increase in percentage of expenses over the years. I chose the Column chart to display this data graphically. The column chart is the best form of chart that can show variation between items.

I selected the Data Range. I specified the start and end values of the data set that I wanted to plot in the chart.

Under Chart Elements, I specified the title and legend for the chart. A legend makes it easy for a viewer to understand a titled graph.

The x-axis represents the year in my column chart, and the y-axis shows the percentage increase in expenses per year. With the help of this chart, I could see that every year the percentage in expenses has increased steadily, and reached the highest value in 2014.

Ben wanted to call his friend Kevin for a game of football. He rang up Kevin and was about to mention the game. Just then, a car nearby honked loudly. Kevin said that he couldn’t hear what Ben said. Ben then repeated what he had said earlier.

Answers

Answer:

The answer to this question is given below in the explanation section.

Explanation:

As you know that noise distracts the process of communication. It is anything that distorts a message between two communicators. Noise can take many forms, such as playing the radio in the background, another person interfering with the conversation, and any other distraction that prevent the receiver from paying attention to what the sender is saying.

So, in this question, the noise phrase in the given passage is written in bold.

Ben wanted to call his friend Kevin for a game of football. He rang up Kevin and was about to mention the game. Just then, a car nearby honked loudly. Kevin said that he couldn’t hear what Ben said. Ben then repeated what he had said earlier.

A car honked nearly when Ben and Kevin are communicating with each other is considered noise. A car honked is a noise in the process of communication.    

Answer:

Just then, a car nearby honked loudly.
