C language | copy strings without strcpy

Example 69: Write a program in C language to copy all the characters in the character array str2 to the character array str1, without using the strcpy function.

Analysis: "\0" should also be copied when copying, and the characters after "\0" will not be copied.

Source code demo:

#include<stdio.h>//头文件 
#include<string.h>//引入求字符串长度的库函数 
int main()//主函数 
{
    
    
  char str1[80],str2[80];//定义字符数组 
  int i;//定义整型变量 
  printf("输入要复制的字符串：");//提示语句 
  scanf("%s",str2);//输入字符串 
  for(i=0;i<=strlen(str2);i++)//遍历 
  {
    
    
    str1[i]=str2[i];//挨个赋值 
  } 
  printf("复制后的字符串是:%s\n",str1);//输出复制后的 
  return 0;//主函数返回值为0 
}

The compilation and running results are as follows:

输入要复制的字符串：love
复制后的字符串是:love
