How to debug ​

Debugging C++ code is crucial for every developer. One of the simplest yet effective ways to debug is by using std::cout statements.

Steps to Debug Using std::cout Statements ​

  1. Identify the Problem Area: Locate the section of your code where you suspect the problem might be.

  2. Insert std::cout Statements: Add std::cout statements before and after the suspected problematic code to print out variable values and flow control.

  3. Check the Results Output of your tests

  4. Analyze the Output: Look at the values printed on the results console to understand what's going wrong in your code. Adjust your code based on the findings and repeat as necessary.

Example ​

Here’s an example of how to use std::cout for debugging:

C++ Code ​

cpp
#include <iostream>

int calculate_sum(int a, int b) {
    std::cout << "calculate_sum called with arguments: " << a << ", " << b << std::endl; // Log function call
    int sum = a + b;
    std::cout << "Sum after addition: " << sum << std::endl; // Log sum calculation
    return sum;
}
