Realize strcmp very easy to think

#define _crt_secure_no_warnings#include<stdio.h> #include <stdlib.h>void strcom (char *str1, Char *str2, int *num) {int a = 0;int count = 0;//key is here to loop inference with a pointer while (*STR1&&*STR2) {str1++;str2++;if ((A=*STR1-*str2)! = 0) { *num = A;return;}}}  void Main () {char *str1 = "Abdda"; char *str2 = "ABDD"; int result = 0;strcom (str1, str2, &result);/inference assumes that the result hypothesis is greater than 0 STR1 greater than str2 otherwise str1 is less than str2   equals 0 if two strings equal if (Result > 0) {printf ("");} System ("Pause");}
