Debugging code using the C debugger involves the following steps: Set breakpoints to pause code execution. Start debugging to enter debug mode. Step through code to examine its execution line by line. Check variable values ​​or evaluate expressions in the immediate window. Through these techniques, developers can gain insight into the inner workings of code and solve problems efficiently.

#Debugging in C Technology: Using the Debugger to Explore Inside Your Code

Introduction
Debugging It is a crucial step in the software development process that allows developers to identify and fix program errors. C language provides powerful debugger tools to help developers debug code easily.

Using the Debugger

Most IDEs (Integrated Development Environments) have built-in debuggers. To start the debugger, follow these steps:

  1. Set a breakpoint: Left-click on the line of code you want to debug.
  2. Start debugging: Select Debug > Start from the IDE menu or press the F5 key.

The debugger will enter debug mode, pausing execution at the breakpoint. Developers can:

  • Step through code in this mode: Press the F10 key to step through code, which can happen when local variable values ​​change.
  • Inspect variables: Hover your mouse over a variable or select Quick Watch in the View menu to see its value.
  • Evaluate expressions: Enter an expression in the Immediate window to evaluate its result.

Practical Example

Consider the following C code snippet:

#include <iostream>

int main() {
  int x = 10;
  int y = 20;

  for (int i = 0; i < 5; i++) {
    x += i;
    y -= i;
  }

  std::cout << "x = " << x << std::endl;
  std::cout << "y = " << y << std::endl;

  return 0;
}
Copy after login

To debug this code snippet, perform the following steps:

  1. Open the code snippet in the IDE.
  2. Set a breakpoint before the for loop begins.
  3. Start debugging.
  4. Step through the code to observe how the values ​​of x and y change.

Conclusion

The debugger in C is a powerful tool for debugging code and fixing errors. By using features such as breakpoints, single-stepping, and variable inspection, developers can gain insight into the inner workings of their code and quickly resolve issues.
