Go Language Debugging Tutorial Using VS Code and Delve

This tutorial introduces how to debug Go programs using VS Code and the Delve debugger.

First, configure the debugging environment in VS Code for Go.

Then, explain the basic debugging toolbar icons: continue (resume execution), step over (execute line by line without entering functions), step into (enter function calls), step out (exit current function), restart and stop to control the debug session, and breakpoint to pause execution at specific lines.

When the program hits a breakpoint, the debugger shows variable values; for example, the variable n can be inspected to verify program state.

Conditional breakpoints allow pausing only when an expression is true, such as n == 7 or a combined condition like (n > 3) && (n % 4 == 0) .

The call stack window displays the sequence of function calls, helping trace parameters and return addresses, which is especially useful for recursive functions like Fibonacci or when a panic occurs.

Mastering these debugging techniques improves efficiency in locating and fixing bugs in Go code.
