I am trying to design an algorithm for a simple calculator function. But everytime i enter in a symbol to have it perform an operation it always adds. Also, the while loop never terminates even when i say no.
#include <iostream>
using namespace std;
Code:
int main ()
{
// Variable Declarations
int num1, num2, num3, num4;
char letter, symbol;
// Prompt
cout << "This Program will add, subtract, multiply, and divide"
<< "the two numbers you enter." << endl;
cout << endl;
while (letter = 'y')
{
cout << "Please enter two numbers: ";
cin >> num1 >> num2;
cout << endl;
cout << "Please input the operation you would like to use: ";
cin >> symbol;
cout << endl;
if (symbol = '+')
{
num3 = num1 + num2;
cout << "The sum is: " << num3 << endl;
}
else if (symbol = '-')
{
num3 = num1 - num2;
cout << "The difference is: " << num3 << endl;
}
else if (symbol = '*')
{
num3 = num1 * num2;
cout << "The product is: " << num3 << endl;
}
else if (symbol = '/')
{
num3 = num1 / num2;
num4 = num1 % num2;
cout << "The quiotient is: " << num3 << "The remainder is: " << num4 << endl;
}
else
cout << "Invalid symbol." << endl;
cout << "Would you like to run the program again [y/n] ";
cin >> letter;
cout << endl;
}
cout << "End of Program" << endl;
return 0;
}
