求一個c語言程序：輸入一組數,求其最大值,最小值,中位數,平均數,方差,標準差及其相關係數.

題目：

求一個c語言程序：輸入一組數,求其最大值,最小值,中位數,平均數,方差,標準差及其相關係數.
要求,程序中有數據排序體現且採用冒泡排序,其中有一個模塊採用宏編寫,但儘量多採用函數編寫,相關係數可選擇編寫.請高手指教,越快越好!

解答：

#include "stdio.h"
#include "time.h"
#include "stdlib.h"
#include "math.h"
#define NUM_OF_INT 30
#define MAX(x,y) x>y?1:0
//排序

\x09\x09\x09}

}
//方差

\x09//不懂你說的相關係數是什麼,是自相關,還是啥呀
