c语言中定义函数和调用函数(计算三个数中的最大值)
1、c语言中定义函数和调用函数(计算三个数中的最大值)
#include <stdio.h>
int max3(int a, int b, int c)
{
int max = a;
if (b > max)
max = b;
if (c > max)
max = c;
return max;
}
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 max = %d\n", max3(n1, n2, n3));
return 0;
}
