How do I properly compare strings in C? #14

Open mucahitdemir opened 2 years ago

mucahitdemir commented 2 years ago

You can't (usefully) compare strings using != or ==, you need to use strcmp:

while (strcmp(check,input) != 0) The reason for this is because != and == will only compare the base addresses of those strings. Not the contents of the strings themselves.

The strcmp() compares two strings character by character. If the strings are equal, the function returns 0.
