Question

Is there a function in c that will return the index of a char in a char array?

For example something like:

char values[] = \"0123456789ABCDEFGHIJKLMN         


        

Answer 1

int index = strchr(values,find)-values;

Note, that if there's no find found, then strchr returns NULL, so index will be negative.
