Help with Simple Calculator

[jbartlett13]

I'm supposed to check for dividing by 0, but every time I try to get it to say error can't divide by 0, it just crashes

again it's super simple. about the 3rd week of class.
I need to check for 0.


#include <iostream>
#include <fstream>

using namespace std;

int main()
{
ofstream outFavs;

outFavs.open("bartlett_txt.txt", ios::app);


int a; //used the int values for the first values
int b;
int c;
int num1, num2;
int integer;


cout << "Enter first number: ";
cin >> num1;

cout << "Enter Second Number: ";
cin >> num2;


if (num2==0)

cout << "can't divide by 0" << endl;


else

cout << "division is: " << num1/num2 << endl;
cout << "remainder is: " << num1 % num2 << endl;


if (num1 > num2)
{
cout << "num1 larger" << endl;
}
else if (num2 > num1)
{
cout << "num2 larger" << endl;
}
else
{
cout << "num1 is equal to num2" << endl;
}


cout << "Enter two numbers: " << endl;
cin >> a >> b;

c = a + b;
cout << "Value of Addition is : " << c << endl;

c = a - b;
cout << "Value of Subtraction is : " << c << endl;

c = a * b;
cout << "Value of Multiplication is : " << c << endl ;

c = a / b;
cout << "Value of Division is : " << c << endl ;

c = a % b;
cout << "Value of Percentage is : " << c << endl ;

c = a++;
cout << "Value of Post-Increment is : " << c << endl ;

c = a--;
cout << "Value of Post-Decrement is : " << c << endl ;
//// couldn't figure out how to correctly space them apart, and to write that the new line was going to represent the values of the decimals.

cout << "Enter two numbers: " << endl;
cin >> x >> y;

cout << "Please enter an integer" << endl;
cin >> integer;
//determine if integer is odd or even

if ( integer % 2==0 )
// if the integer when divided by 2 has no remainder its even.

cout << integer << " is even " << endl;

else
// the integer is odd

cout << integer << " is odd " <<endl;


outFavs.close();


system("pause");
return 0;
}

This code doesn't compile, so I don't know what code you're actually using.

Anyway, find all the division operations in your code, and for each of them check the divisor. If the divisor is zero, don't do the division.
