String-Handling Functions
With the declaration and initialization:
s1[10] ="The ";
s2[4] = "CZ";
s3[5] = "The ";
The function (with string.h included)
strcmp(s1, s2) returns a positive value (for 'T' is after 'C' according to ASCII table).
strcmp(s1, s3) returns 0 (for the two strings are the same).
