求教程序代码

Answer 1

# include<stdio.h>

void pra(int num)// 输出众数个数 众数 次数
{
    double buff[30][2];//保存输入元素 及出现次数
    double buff2[30];
    double t;
    int n = 0, i, j;
    int max_n = 0;//最高出现次数

    if( 0 == num)
        return;
    else
    {
        //输入数据
        for(n = 0; n < num ; n++)
        {
            scanf("%lf", &buff[n][0]);
            buff[n][1] = 0.0;
        }
         //排序(前面)
        for(i = 0;i< num-1;i++)
        {
