Often when we run into the warning saying warning: control reaches end of non-void function . Generally, we ignore this error because most of the time as the program still runs the same even if this warning is coming. Let’s first see a simple example then this kind of error can occur. #include <bits/stdc++.h> using namespace std; int fun(){ if(false) return 0; } // Error here int main() { fun(); return 0; } If we run this c++ code it works fine and terminates but we get an error at the 8th line saying control reaches end of non-void function.
