strcmp #include <cstring> int strcmp( const char *str1, const char *str2 ); The function strcmp() compares str1 and str2, then returns: Return value Explanation less than 0 str1 is less than str2 equal to 0 str1 is equal to str2 greater than 0 str1 is greater than str2 For example: printf( "Enter your name: " ); scanf( "%s", name ); if( strcmp( name, "Mary" ) == 0 ) { printf( "Hello, Dr. Mary!\n" ); } Note that if str1 or str2 are missing a null-termination character, then strcmp() may not produce valid results. For a similar (and safer) function that includes explicit bounds checking, see strncmp(). Related topics memcmp - strcat - strchr - strcoll - strcpy - strlen - strncmp - strxfrm
