1、最大值
#include <stdio.h>
int main(void) { int a,b,c,d,m; puts("please input four integers."); printf("a = "); scanf("%d", &a); printf("b = "); scanf("%d", &b); printf("c = "); scanf("%d", &c); printf("d = "); scanf("%d", &d); m = a; if (m == b && m ==c && m ==d) puts("the integers are equal!\a"); else { m = (m > b) ? m:b; m = (m > c) ? m:c; m = (m > d) ? m:d; printf("the larger integer is %d.\n", m); } return 0; }
2、最小值
#include <stdio.h>
int main(void) { int a,b,c,d,m; puts("please input four integers."); printf("a = "); scanf("%d", &a); printf("b = "); scanf("%d", &b); printf("c = "); scanf("%d", &c); printf("d = "); scanf("%d", &d); m = a; if (m == b && m == c && m == d) puts("the integers are equal!\a"); else { m = (m < b) ? m:b; m = (m < c) ? m:c; m = (m < d) ? m:d; printf("the smaller integer is %d.\n", m); } return 0; }
