如何用函数调用实现字符串的复制？

Question

请应用指针，主函数初始化2个字符数组，char a[80]=” I am proud of the development of Huaiyin Institute of Technology!”,char b[80]=” I'm a university student!”;用函数调用实现字符串的复制。

Answer 1

#include <stdio.h>
char *strCpy(char *a,char *b)
{
    int i=0;
    do
    {
        a[i] = b[i];
    }while(b[i++] != 0);
    return a;
}
int main()
{
    char a[80]="I am proud of the development of Huaiyin Institute of Technology!";
    char b[80]="I'm a university student!";  
    printf("%s",strCpy(a,b));
    return 0;
}
