实验任务1_1
#include<stdio.h>
int main()
{
printf(" O \n");
printf("<H>\n");
printf("I I\n");
printf(" O \n");
printf("<H>\n");
printf("I I\n");
return 0;
}
实验任务1_2
#include<stdio.h>
int main()
{
printf(" O O \n");
printf("<H> <H>\n");
printf("I I I I\n");
return 0;
}
实验任务2
#include<stdio.h>
int main()
{
float a, b, c;
scanf("%f%f%f", &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;
}
实验任务3
#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表示木有敲): ");
ans2 = getchar();
if((ans1 == 'y' || ans1 == 'Y') && (ans2 == '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;
}
getchar();的作用是消除回车对结果的影响
实验任务4
#include<stdio.h>
int main()

printf("a1 = %d, a2 = %d, a3 = %d\n", a1, a2, a3);
scanf("%c%c%c", &c1, &c2, &c3);
printf("c1 = %c, c2 = %c, c3 = %c\n", c1, c2, c3);
scanf("%lf%lf", &x, &y);//double对应的应为lf
printf("x = %lf, y = %lf\n",x, y);
return 0;

实验任务5
#include<stdio.h>

int year;

}
return 0;
}
实验任务7
#include<stdio.h>
int main()

double s, S, area;
while(scanf("%d%d%d", &a, &b, &c) != EOF)
