Question

求大神。。下面复制字符串的程序哪错了？

#include<stdio.h>
#include<string.h>
int main()
{char fz(char a[],char b[]);
char s1[20],s2[10],c;
printf("输入字符串：");
scanf("%s",&s2);
c=fz(s1,s2);
printf("复制后s1数组为%s\n",c);
return 0;}

char fz(char a[],char b[])
{int i;
for(i=0;i<strlen(b);i++)
a[i]=b[i];
a[i]='\0';
return(a[i]);
}

Answer 1

改为
#include<stdio.h>
#include<string.h>
int main()
{char * fz(char a[],char b[]);
char s1[20],s2[10];
char *c;
printf("输入字符串：");
scanf("%s",&s2);
c=fz(s1,s2);
printf("复制后s1数组为%s\n",c); //char 型的c怎么能用%s
return 0;}

char * fz(char a[],char b[])
{int i;
for(i=0;i<strlen(b);i++)
a[i]=b[i];
a[i]='\0';
return(a); //a[i]是'\0'，返回干什么
}
