Syntax int strcmp (string1, string2); If the difference is equal to zero, then string1 = string2. STRCMP() Compare two strings If a string function is given a binary string as an argument, the resulting string is also a binary string. strcmp (a, b) returns 0 if both the strings a and b are exactly same else returns -1. It returns the ASCII difference of the first two non matching characters in both the strings. Conclusion strcmp() in C++. Do not forget to include string.h header file. If an unmatched character is found then strings are not equal. returns positive integer: if string1 > string2. The syntax for the strcmp function in the C Language is: int strcmp(const char *s1, const char *s2); Parameters or Arguments s1 An array to compare. Strcmp is one of the most used comparison functions of the C language. In this program we will compare strings using strcmp () function defined in the string.h library. Case 2: when the strings are unequal, it returns the difference between ascii values of the characters that differ. It returns -1, 0, 1, respectively, if S1 is less than S2 , equal to S2, or greater than S2. String compare is also one form of predefined inbuild functions of string.h header file as part of the string class.
