用程序实现strcat,strcpy函数功能

strcpy #include<stdio.h> #include<string.h> maid() { char a={"asd "}; char b[20]={"dsa"}; int c=0,d=0; while(a[c]!="/0") c++; while(b[d]!="/0") { a[c]=b[d]; c++;d++; } a[c]="/0"; puts(a); }strcat
#include<stdio.h>
#include<string.h>
maid()
{
char a={"asd"};
char b[20];
int c=0;
while(a[c]!="/0")
{
b[c]=a[c];
c++;
}
b[c]="/0";
puts(b);
}
做出来之后,都运行不了。到底那里错了
