Question

C++ program by using while loop structure.

Write an interactive program (C++) to prompt and read two float type numbers, Then your program should perform and print the following arithmetic: (use while loop structure to repeat program 2 times. 1) Sum 2)Difference 3) Product 4) Quotient 5) Modulus (use system defined fmod function) You must use system's defined function prototype and/or to create programmer's defined function prototype for each of the above calculation. In addition, create a function called "DISPLAYLINE " using looping concept and a single print statement to create a line of Add (#) signs.

Answer 1

C++ Program:

#include<iostream>

#include <math.h>

using namespace std;

void DISPLAYLINE(){

for(int i=0;i<21;i++){

cout<<" # ";

}

}

int main(){

int i=0;

while(i<2){

float a,b,sum,diff,prod,quotient,mod;

cout<<"Enter number 1: ";

cin>>a;

cout<<"Enter number 2: ";

cin>>b;

sum=a+b;

diff=a-b;

prod=a*b;

quotient=a/b;

mod=fmod(a,b);

cout<<"Sum of num1 and num2 = "<<sum<<endl;

cout<<"Diff of num1 and num2 = "<<diff<<endl;

cout<<"Product of num1 and num2 = "<<prod<<endl;

cout<<"Quotient of num1/num2 = "<<quotient<<endl;

cout<<"Mod of num1 and num2 = "<<mod<<endl;

DISPLAYLINE();

i++;

}

}

Answer 2

Here's a C++ program that fulfills the requirements mentioned:

cppCopy code#include <iostream>#include <cmath>void displayLine(int n){    for (int i = 0; i < n; i++)
    {
        std::cout << "#";
    }
    std::cout << std::endl;
}float sum(float num1, float num2){    return num1 + num2;
}float difference(float num1, float num2){    return num1 - num2;
}float product(float num1, float num2){    return num1 * num2;
}float quotient(float num1, float num2){    return num1 / num2;
}float modulus(float num1, float num2){    return std::fmod(num1, num2);
}int main(){    int count = 0;    while (count < 2)
    {        float num1, num2;
        std::cout << "Enter two numbers: ";
        std::cin >> num1 >> num2;

        std::cout << "Sum: " << sum(num1, num2) << std::endl;
        std::cout << "Difference: " << difference(num1, num2) << std::endl;
        std::cout << "Product: " << product(num1, num2) << std::endl;
        std::cout << "Quotient: " << quotient(num1, num2) << std::endl;
        std::cout << "Modulus: " << modulus(num1, num2) << std::endl;        displayLine(30);

        count++;
    }    return 0;
}

In this program, we have defined functions for each arithmetic operation: sum, difference, product, quotient, and modulus. The displayLine function is responsible for printing a line of "#" signs.

The main function uses a while loop to repeat the program's execution two times. Inside the loop, it prompts the user for two float numbers, performs the arithmetic calculations using the defined functions, and prints the results. After each iteration, the displayLine function is called to print a line of "#" signs.

Note: The program assumes that the user will enter valid input (float numbers) and does not include input validation. It's always a good practice to include appropriate input validation checks in a real-world program.
