Set Break Release For Free

A breakpoint instructs the debugger to stop at a particular code location in the user's program, returning control of the debugger to them. The user may then inspect the application's state. Breakpoints are by far the most common type of debug event that developers use.

To set a breakpoint in source code: Click in the far left margin next to a line of code. You can also select the line and press F9, select Debug > Toggle Breakpoint, or right-click and select Breakpoint > Insert breakpoint.

You can debug a release build of an application.

For example, if a function is simple and only called once, the compiler can inline the function in release mode. Debug mode doesn't have these kind of optimization and is designed for debugging your code. You can then put a breakpoint on that int declaration line, and it'll be hit, even in release mode.

Visual Studio projects have separate release and debug configurations for your program. You build the debug version for debugging and the release version for the final release distribution. In debug configuration, your program compiles with full symbolic debug information and no optimization.

Setting breakpoints A breakpoint is like a stop sign in your code -- whenever gdb gets to a breakpoint it halts execution of your program and allows you to examine it. To set breakpoints, type "break [filename]:[linenumber]". For example, if you wanted to set a breakpoint at line 55 of main.

If a source file has changed and the source no longer matches the code you're debugging, the debugger won't set breakpoints in the code by default. Normally, this problem happens when a source file is changed, but the source code wasn't rebuilt. To fix this issue, rebuild the project.
