用for、while、do-while循环输出10句“好好学习，天天向上！”

#include "stdio.h"
void main()
{
    int time;
    for (time=1;time<=10;time++)
    printf("%d、好好学习，天天向上！\n",time);
}

#include "stdio.h"
void main()
{
    int time=1;
    while (time<=10)
    {
    printf("%d、好好学习，天天向上！\n",time);
    time++;
    }
}

#include "stdio.h"
void main()
{
    int time=1;
    do 
    {
    printf("%d、好好学习，天天向上！\n",time);
    time++;
    }
    while(time<=10);
}
