例1:输出This is a C program
#include<stdio.h> int main() { printf("This is a C program\n"); return 0; }
例2:求两个整数之和
#define _CRT_SECURE_NO_WARNINGS #include<stdio.h> int main() { int a = 0; int b = 0; int sum = 0; scanf("%d%d",&a,&b); sum = a + b; printf("sum= %d\n",sum); return 0; }
例3:求两个整数中最大值
#define _CRT_SECURE_NO_WARNINGS #include<stdio.h> int main() { int a = 0; int b = 0; int max = 0; scanf("%d%d", &a, &b); max=(a>b?a:b); printf("max= %d\n", max); return 0; }
输出信息
**************
Very good!
**************
#include<stdio.h> int main() { printf("**************\n"); printf("Very good!\n"); printf("**************\n"); return 0; }
输入a,b,c,输出最大值
#define _CRT_SECURE_NO_WARNINGS #include <stdio.h> int main() { int a, b, c, max; printf("please input a,b,c:\n"); scanf("%d,%d,%d",&a,&b,&c); max = a; if (max < b) max = b; if (max < c) max = c; printf("The largest number is %d\n", max); return 0; }
#define _CRT_SECURE_NO_WARNINGS #include<stdio.h> int main() { int max(int x, int y, int z); int a, b, c, d; scanf("%d %d %d", &a, &b, &c); d = max(a, b, c); printf("max = % d\n",d); return 0; } int max(int x, int y, int z) { int g; if (x > y && x > z) g = x; else if (y > x && y > z) g = y; else if (z > x && z > y) g = z; return (g); }
