//打印一个字符小人 #include <stdio.h> int main() { printf(" o\n"); printf("<H>\n"); printf("I I\n"); return 0; }
#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; }
//打印一个字符小人 #include <stdio.h> int main() { printf(" o o\n"); printf("<H> <H>\n"); printf("I I I I\n"); return 0; }
#include<stdio.h> int main() { int n, sum; scanf("%d", &n); sum = n*(n+1)/2; printf("sum = %d\n", sum); return 0; }
写法1写法2能实现
#include<stdio.h> int main() { int a, b, t; a = 3; b = 4; printf("a = %d, b = %d\n", a, b); t = a; a = b; b = t; printf("a = %d, b = %d\n", a, b); return 0; }
使ab的值实现交换
#include<stdio.h> int main() { int x, t, m; x = 123; printf("x = %d\n", x); t = 0; m = x % 10; t = t * 10 + m; x = x / 10; m = x % 10; t = t * 10 + m; x = x / 10; m = x % 10; t = t * 10 + m; x = x / 10; printf("t = %d\n", t); return 0; }
使数据位置颠倒
#include<stdio.h> int main() { float a, b, c; scanf("%f%f%f", &a,&b,&c); if(a+b>c) printf("能构成三角形\n"); else printf("不能构成三角形\n"); return 0; }
#include <stdio.h> int main() { int year; year = 1000000000/60/60/24/365; printf("10亿秒约等于%d年\n", year); return 0; }
#include<stdio.h> #include<stdlib.h> int main() { int n; n = rand()%41+60; printf("n = %d\n", n); return 0; }
#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'&&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; }
