Answer 1

You can use strcmp :

 #include <stdio.h> #include <string.h> int main(int argc, char **argv) { int v; const char *str1 = "hello"; const char *str2 = "world"; v = strcmp(str1, str2); if (v < 0) printf("'%s' is less than '%s'.\n", str1, str2); else if (v == 0) printf("'%s' equals '%s'.\n", str1, str2); else if (v > 0) printf("'%s' is greater than '%s'.\n", str1, str2); return 0; } 

Result:

 'hello' is less than 'world'.
