这个程序错哪了,为什么调试时没错,却无法执行,提示出错.
#include<stdio.h>
#include<string.h>      
main(){
        int i,n,m=4,v=0;
            char *su[5]={"MM","ht","hx","mh","fk"};
            printf("%s %s %s %s",su[m-1],su[2],su[3],su[4]);
        for(i=1;i<=4;i++){
            for(n=1;n<=5-i;n++){
                if(strcmp(su[m],su[m-n])==0){
                  v++;
                  printf("%d\n",v);}
            m=m-1;    
        }     
        }   
        printf("%d\n",v);
