C语言strcpy()库函数的实现

char stra;
const  char strb;

char *strcpy(stra,strb);
/*其中stra数组必须大于或等于strb数组，函数会把strb指向的字符串复制到str1中去，strb必须是终止符为'/0'的字符串指针*/

#include <stdio.h>
#include <stdlib.h>
#define N 80
void  MyStrcpy( char *dstStr, char *srcStr );
int main()
{
char a
,b
;
printf("Please enter a string:\n");
gets(a);
MyStrcpy(b,a);
printf("The copy is:%s",b);
return 0;

}
void  MyStrcpy( char *dstStr, char *srcStr ){
int i=0;
while(srcStr[i]!='\0'){
dstStr[i]=srcStr[i];
i++;
}
dstStr[i]='\0';

}
