assert example 1: basics is an assert example.
A division will only succeed if the denominator is unequal to zero. In your code, you will have to take care that a division by zero never occurs. Using assert, as shown in the code below, will take you to the problem directly.
#include <cassert>
#include <iostream>
int main()
{
const double numerator = 1.0;
const double denominator = 0.0;
assert(denominator != 0.0);
const double result = numerator / denominator;
std::cout << result << '\n';
}Screen output:
Assertion failed!
Program: /my_path/my_program
File: my_path/main.cpp, Line 7
Expression: denominator != 0.0
