函数实现my_strcpy.

#include<stdio.h>char *my_strcpy(char a[], char const *b){int i=0, j=0;while (*(b + j) != '\0'){a[i] = *(b + j);i++;j++;}a[i] = *(b + j);return 0;}int main(){char arr[20] = {};char *brr = "abcdefg";my_strcpy(arr, brr);printf("%s\n", arr);return 0;}<img src="" alt="" style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);" />
