在C语言中比较两字符串(自定义函数)

int result;
char c[255];

int compStr(char a[255],char b[255])
{
/*int result;*/
int len,i;
len=strlen(b);
for (i=0;i<len;i++)
{
if(a[i]!=b[i])
{
break;
}
}
if (len==i)
{
/*strcpy(result,"match");*/
result=1;
}
else
{
/*sprintf(result,"%s","Mismatch");*/
result=0;
}
return result;
}

#include "compstr.c"

main()
{
char a[255],b[255];
int len,i;
strcpy(a,"test");	/*set value*/
printf("please input a string:");
scanf("%s",b);
printf("result:%d\n",compStr(a,b));
sprintf(c,"%s","cccc");
printf("c=%s",c);
}
