c - 为什么我不能让这个简单的 C 程序运行？

Question

我正在制作一个简单的控制台程序，该程序应该使用户能够输入一个数组，并且该程序应该显示所有数字的算术平均值，但无论我尝试什么，我都无法让它工作。这里有人能指出为什么这不起作用吗？

(这是塞尔维亚语，但您可能可以看到什么是什么。)

编辑:运行此代码时出现这些错误:

||=== Build file: "no target" in "no project" (compiler: unknown) ===|
F:\rastko\Documents\Code\C\Test1\main.c||In function 'main':|

然后程序崩溃了。我不知道这意味着什么，而且在技术演讲方面我的英语不是最好的，因为我正在学习如何用塞尔维亚语编码。

#include <stdio.h>
#include <stdlib.h>
#define MAX 41

int BrojElemenataNiza(unsigned int brElem)
{

    if (brElem <= MAX){
        return brElem;
    }
    else {
        return 69;
    }
}

void UnesiElementeNiza(int niz[0], unsigned int brElem)
{
    for (unsigned int i = 0; i < brElem; ++i)
    {
        printf("niz[%u] = ", i);
        scanf("%d", &niz[i]);
    }

}

double AritmetickaSredinaNiza(int niz[0], unsigned int brElem)
{
    int j = 0;
    for (unsigned int i = 0; i < brElem; ++i)
    {
        j = j + niz[i];
    }
    return j/brElem;
}

int main()
{
    int n, m, j, niz[0];

    printf("unesite broj elemenata niza\n");
    scanf("%d", &n);                            //unos broja elemenata niza
    int brElem = BrojElemenataNiza(n);

    printf("unesite elemente niza\n");          //unos elemenata niza
    UnesiElementeNiza(niz[brElem], brElem);

    double arSredina = AritmetickaSredinaNiza(niz[0], brElem);
    printf("aritmeticka sredina niza je ");
    printf("%lf", arSredina);


    return 0;
}

这个怎么样，抱歉，是英语，我不会说塞尔维亚语。

#include "stdlib.h"
#include "string.h"
#include "stdio.h"

#define MAX 41

int check(unsigned int brElem)
{

    if (brElem <= MAX){
        return brElem;
    }
    else {
        return 69;
    }
}

void num_to_array(int *niz, unsigned int brElem)
{
    for (unsigned int i = 0; i < brElem; ++i)
    {
        printf("niz[%u] = ", i);
        scanf("%d", &niz[i]);
    }

}

double average(int niz[0], unsigned int brElem)
{
    int j = 0;
    for (unsigned int i = 0; i < brElem; ++i)
    {
        j = j + niz[i];
    }
    return j/brElem;
}

int main()
{
    int n, m, j, niz[MAX];

    printf("how many numbers ?\n");
    scanf("%d", &n);              //unos broja elemenata niza
    int brElem = check(n);

    printf("enter numbers\n");    //unos elemenata niza
    num_to_array(niz, brElem);

    double arSredina = average(niz, brElem);
    printf("aritmeticka sredina niza je ");
    printf("%lf", arSredina);


    return 0;
}
