1、c语言中定义函数和调用函数（计算三个数中的最小值）
#include <stdio.h>
int min3(int a, int b, int c) { int min = a; if (b < min) min = b; if (c < min) min = c; return min; } int main(void) { int n1, n2, n3; puts("please input three integers."); printf("n1 = "); scanf("%d", &n1); printf("n2 = "); scanf("%d", &n2); printf("n3 = "); scanf("%d", &n3); printf("the min = %d", min3(n1, n2, n3)); return 0; }
