assert is a function available in the cassert header file that enables immediate termination of a program if an expression evaluates to false. It can be used to exit from a program at any point, even inside a function.
#include <iostream>
#include <cassert>
int main()
{
cout << "Enter numerator: ";
double numerator;
cin >> numerator;
cout << "Enter denominator: ";
double denominator;
cin >> denominator;
assert(denominator != 0);
cout << "Result is: " << numerator / denominator << endl;
return 0;
}
The result of the above program being run and the input for the denominator being 0 will be:
