Hi everyone. I'm having a tough time figuring out this c programming problem. It can only use <stdio.h> and here is the problem:
Write a program which includes a user defined function named 'upper' . The function is passed a single char. It will return 1 if the char is upper case, i.e. between ‘A’ and ‘Z’. It will return 0 otherwise. Your main function will ask the user to enter input char, call the function, and
print out the answer.
If anyone could help me with this I'd be really appreciative! Thanks!
