C language programming> 26th week ④ Please add the main function, the function of this function is: input a string from the keyboard and save it in character s1, and save the odd-numbered characters in string s1 in string s2 In and output.

Example: Please add the main function. The function of this function is to input a character string from the keyboard and store it in character s1, and store the odd-numbered characters in character string s1 in character string s2 and output it.

例如，当s1= “asdfgh”时，则s2= “sfh”。
请勿改动主函数main与其他函数中的任何内容，仅在fun函数的横线上填写所需的若干表达式或语句。

代码如下：

#include<stdio.h>
#include<conio.h>
#define N 80
main()
{
    
    
	char s1[N],s2[N];
	char*temp1=s1,*temp2=s2;
	int i=0,j=0;
	printf("Please Enter the string:");
	scanf("%s",s1);
	printf("\nThe original string is:");
	while(*(temp1+j))
	{
    
    
		printf("%c",*(temp1+j));
		j++;
	}
	for(i=1;i<j;i+=2)
		*temp2++=*(s1+i);
	*temp2='\0';
	printf("\n\nThe new string is:%s\n",s2);
}

The output running window is as follows:
