#include<malloc.h>
#include<assert.h>
char *mystrcpy(char *strdest,const char *strsrc)
{
assert((strdest !=NULL )&& (strsrc !=NULL));
char *address=strdest;
while((*strsrc!='\0')&&(*strdest!='\0') )
{
*strdest = *strsrc;
strdest++;
strsrc++;
}
return address;
}
int main(void)
{
char *str1=(char *)malloc(5);
char *str2="aaaaa";
printf(str2);
mystrcpy(str1,str2);
printf(str1);
getchar();
return 0;
}
这是我自己写的mystcpy，希望能帮到你。

{
char data[100] = {0};
char *a, *b;
int length = 0;
sanf("%c", data);
b = data;
while (*b)
{
length++;
}
a = (char *)malloc((length + 1) * sizeof(char));
memset(a, 0, ((length+1)*sizeof(char));
for (int index = 0; index < length; index++)
{
*(a + index) = *(b + index);
}
printf("%s\n", a);
}
