Warm up:C input and output

谨以此练习来学习最基础的C语言输入和输出。

Description

This is an exercise for you to get prepared for C language programming.

All you have to do is to accept a string as input, and print it character by character. Characters are separated by new line.

The difficulty lies in deciding wether the string ends or not, and 'EOF' is used to solve the problem(see hint).

Input

A string.

Output

Print those characters of the given string, one character per line.

Sample Input

Hi!

Sample Output

H
i
!

HINT

Kernel code:

char ch;

while(scanf("%c",&ch) != EOF) {

    // DO SOMETHING

}

#include <stdio.h> //头文件，标准输入输出
#include <stdlib.h>

int main()
{   int ch;
while(scanf("%s",&ch)!=EOF){
printf("%s\n",ch);};

return(0);
