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

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; }
