After getting replies (also on CS50 eDX forum) and reworking, here is the code that seems to achieve the intermittent goal of finding ASCII code of entered characters. There was no need of while loop and it was an error as the same leads to infinite loop. Even if there was a need, I should perhaps have opted for if command.

It does this because of the logic that was implemented in the code. Think about what the code does. Even though it's running a loop, the code is going to check the first character in the input string. Whether it's a number or not, it's going to terminate because of the return statements in both if statements. A return statement in main will immediately ...
