PFA, The debugger is supposed to step into the reverse() function. But it is opening these tabs.

CodePudding user response：

The debugger is stepping into the std::string(const char*) constructor. Your code calls this implicitly before calling reverse because you pass "binod" (which effectively has type const char*) to a function expecting a std::string.

There's nothing wrong here, it's not the wrong function, just a function you didn't realise was being called. Just step out and then step in again.

Side note: Visual Studio's debugger has the 'Just My Code!' feature which, when enabled, means the debugger only steps into code you wrote. Can be a useful time saver.
