How to debug dev c? -dev c Chinese debugging
Article Introduction:Use and debugging of devc: 1. Use breakpoint debugging if it cannot be debugged: Tools –> Compile options –> Code generation/optimization –> Connector –> Generate debugging information –> Change no to yes. Basic steps for debugging; 1. Change the release mode in the upper right corner to debug mode 2. Set breakpoints 3. Click Compile All and click the check mark (a blue arrow indicates that the statement has not been executed yet and is about to be executed, but there are more than one blue line) , variables can be viewed in two ways after debugging, ① Add View to enter the variable value and view ② Select the variable or expression and click Add View to see the variable value in the left column) Of course, through the terminal The console can also observe the value of variables

Debugging and testing of golang functions
Article Introduction:There are three techniques for debugging and testing Go functions: using the debugger dlv to step through the code, inspect variables, and modify the code state. Test functions by writing test functions in the _test.go file and verifying the results using assertion functions. In actual combat, you can use dlv to debug the execution of the function, and use the test framework and assertion function to verify the correctness of the function.

The Pitfalls of Recursion in C++ Debugging: Understanding the Call Stack and Debugging Techniques
Article Introduction:Pitfalls of recursion in C++: Stack overflow: Recursive calls may cause insufficient stack capacity. Use a debugger to trace the call stack and optimize the recursive algorithm. Infinite recursion: There is an error or omission in the recursive base case, resulting in continuous calls to itself, checking the recursive base case and using the memo optimization algorithm. Forked debugging: Recursion in multi-threads may result in incomplete debugging information. Use a concurrent debugger or optimization algorithm to ensure multi-thread safety.
