实现一个strcpy函数

#include<stdio.h>

#include<assert.h>

char   my__strcpy(char*dest, const char *src)

{

assert(dest != NULL);

assert(src);

while (*src != ‘\0‘)

{

*dest = *src;

dest++;

src++;

}

*dest = ‘\0‘;

}

int main()

{

char arr1[30];

char *arr2 = { "student a am i" };

ret=my__strcpy(arr1, arr2);

printf("%s\n", arr1);

system("pause");

return 0;

}
