What could be causing my program to hang on cin.getline() in C++ code?
Click For Summary
SUMMARY
The discussion centers on issues with the C++ function cin.getline() hanging during execution, particularly when used in conjunction with cin.ignore(). The user reports that the program hangs on cin.getline() calls, while cin >> works correctly. The problem arises from improper use of cin.ignore(), which can lead to unexpected behavior if not used correctly, particularly when the input buffer is empty. The consensus is that cin.ignore() should only be used when necessary, specifically after cin >> statements, to clear the newline character left in the input buffer.
