任务1

test1_1.c 

#include <stdio.h>

int main()
{
    printf(" o \n");
    printf("<H>\n");
    printf("I I\n");

    return 0;
}     

test1_2.c

#include <stdio.h>

int main()
{
    printf(" o     o \n");
    printf("<H>   <H>\n");
    printf("I I   I I\n");

    return 0;
}     

 

test2.c

#include <stdio.h>

int main()
{
    double a, b, c;
    scanf_s("%lf%lf%lf", &a, &b, &c);

    if (a + b >= c && a + c >= b && b + c >= a)
        printf("能构成三角形\n");
    else
        printf("不能构成三角形\n");

    return 0;
}     

test3.c

#include <stdio.h>

int main()
{
    char ans1, ans2;
    printf("每次课前认真预习、课后及时复习了没?(输入y或Y表示有,输入n或N表示没有):");
    ans1 = getchar();
    getchar();
    printf("\n动手敲代码实践了没?(输入y或Y表示敲了,输入n或N表示没有敲):");
    ans2 = getchar();
    if (ans1=='y'&&ans2=='Y'||ans1=='y'&&ans2=='Y')
        printf("\n罗马不是一天建成的,继续保持哦:)\n");
    else
        printf("\n罗马不是一天毁灭的,我们来建设吧\n");

    return 0;
}     

回答问题

结果会直接跳出后面的所有内容,getchar();可以读取换行符

test4.c

#include <stdio.h>

int main()
{
    double x, y;
    char c1, c2, c3;
    int a1, a2, a3;

    scanf_s("%d%d%d", &a1, &a2, &a3);
    printf("a1=%d,a2=%d,a3=%d\n", a1, a2, a3);

    scanf_s("%c%c%c", &c1, &c2, &c3);
    printf("c1=%c,c2=%c,c3=%c\n", c1, c2, c3);

    scanf_s("% lf % lf", &x, &y);
    printf("x=%lf,y=%lf\n",x, y);

    return 0;
}     

test5.c

#include <stdio.h>

int main()
{
    int year;
    int seconds;
    scanf_s("%d", &seconds);
    year = (seconds / (60 * 60 * 24 * 365))+0.5;
    printf("10亿秒约等于%d年\n", year);

    return 0;
}

 teat6.c

#include <stdio.h>
#include <math.h>

int main()
{
    double x, ans;

    while(scanf_s("%lf",&x)!=EOF)
    {
        ans = pow(x, 365);
        printf("%.2f的365次方:%2f\n", x, ans);
        printf("\n");
    }
   
    return 0;
}

test7.c

#include <stdio.h>

int main()
{
    double c, f;

    while(scanf_s("%lf", &c)!=EOF)
    {
        f = 9 * c / 5 + 32;
        printf("摄氏度c=%.2f时,华氏度f=%.2f", c, f);
        printf("\n");

    }

    return 0;
}

test8.c

#include <stdio.h>
#include <math.h>

int main()
{
    int a,b,c;
    double s,area;

    while(scanf_s("%d%d%d", &a,&b,&c)!=EOF)
    {
        s = (a + b + c) / 2;
        area = sqrt(s * (s - a) * (s - b) * (s - c));
        printf("a=%d,b=%d,c=%d,area=%.3f", a, b, c, area);
        printf("\n");
    }

    return 0;
}
