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 { if (b > m) m = b; if (c > m) m = c; if (d > m) m = d; printf("the larger 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 { if (b < m) m = b; if (c < m) m = c; if (d < m) m = d; printf("the smaller integer is %d.\n", m); } return 0; }
