Hey to check that the user is entering just alpha I have it set as:
If (!isalpha(argv[1])) && (argc != 2)
{
Yell at user
}
The argc check works fine on its own. The isalpha check returns a segmentation fault. Then I am not able to use the && to combine them, I get an error. What am I doing wrong?
isalpha() takes a single character as a parameter. You are trying to shove an entire string down its throat, so it chokes on it and gives you back a seg fault.
If you want to check the string, you need to loop through argv[1] and check each char individually.
If this answers your question, please click on the check mark to accept. Let's keep up on forum maintenance. ;-)
