简单的c语言程序：实现输入输入数据并进行比较

#include <stdio.h>

void max_min(int a[], int n, int *pmax, int *pmin);
int main()
{
    int i = 0;
    int arr[100] = {0};
    int num = 0;
    int max = 0;
    int min = 0;
    printf("请输入需要比较的数：");
    for(i=0;i<10;i++)
    {
        scanf("%d",arr+i);
        num ++;
        if(getchar()=='
')
        {
            break;
        }
    }
    printf("输入的数据个数是：%d
", num);
    max_min(arr, num, &max, &min);
    printf("max=%d
min=%d
", max, min);
    return 0;

}

void max_min(int a[], int n, int *pmax, int *pmin)
{
    int j = 0;
    int max = 0;
    int min = 0;
    max = a[0];
    min = a[0];
    for(j=1;j<n;j++)
    {
        if(max<a[j])
        {
            max = a[j];
        }
        if(min>a[j])
        {
            min = a[j];
        }
    }
    *pmax = max;
    *pmin = min;
}

执行结果：

momo@momo ~/myfile/mydev/cc
  % compare                                                                                                                         !2150
请输入需要比较的数：1 2 8 9 21
输入的数据个数是：5
max=21
min=1
