[推荐]第二课代码讲义：三个练习 - C语言程序设计 - 课外天地李树青

1）度过的天数

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int age;
    printf("input your age:\n");
    scanf("%d",&age);
    age*=365;
    printf("Your days: %d!",age);

return 0;
}

2）三个数的最大值
#include <stdio.h>
#include <stdlib.h>

int main()
{

    int number1,number2;
    int max;
    scanf("%d",&number1);
    scanf("%d",&number2);

    if(number1<=number2)
    {
        max=number2;
    }
    else
    {
        max=number1;
    }
    printf("%d",max)

return 0;
}

#include <stdio.h>
#include <stdlib.h>

int main()
{

    int number1,number2,number3;
    int max;
    scanf("%d",&number1);
    scanf("%d",&number2);
    scanf("%d",&number3);

    if(number1<=number2)
    {
        max=number2;
    }
    else
    {
        max=number1;
    }

    if(max<=number3)
    {
        max=number3;
    }

printf("%d",max);

return 0;
}

3）圆面积的计算

#include <stdio.h>
#include <stdlib.h>

#define PI 3.14

int main()
{
float r,area;
scanf("%f",&r);

area=PI*r*r;

printf("%5.1f",area);

return 0;
}
