c语言 判断两个字符串是否相等

#include <stdio.h>

#include <string.h>

int fun(char *a,char *b)

{

int i,flag=0;

for(i=0;a[i]!='\0'&&b[i]!='\0';)

if(a[i]==b[i])

i++;

else

{

flag=0;

break;

}

if(a[i]=='\0'&&b[i]=='\0')

flag=1;

return flag;

}

int main()

{

char *a="12345";

char *b="1235";

int c;

c=fun(a,b);

printf("%d\n",c);

}
