Can someone help me fix this code?

[abc456]

I'm supposed to write a program that tests the “randomness” of the C++ random number generator.
Your program should generate 10,000 random numbers between 0 and 99. It would keep track of how many times each number was generated.
Have the program report the following information:
 Median number of times each number was generated
 Maximum times a number was generated (and which numbers they were)
 Minimum times a number was generated (and which numbers they were)
I don't understand what I did below. I tried to generate random numbers, put them into an array and I made a function to find the median. However I have no clue how to figure out max/min times a number was generated and which they were and also I don't know how to fix the code I have so far. Thanks in advance!

#include <cstdlib>
#include <ctime>
#include <iostream>

using namespace std;
int numbers[100]; //to store numbers from 0 - 99

int main()
{
    
    for(int i =0; i<10000; i++)
    {
       int number = rand() % 10000 + 1;
        numbers[number]=0; //Fill with zeros
    }
    
    srand(time(NULL));
    
    for(int i =0; i<10000; i++)
    {
        int number = rand() % 10000 + 1;
        
        numbers[number]++; //To count each time a number appears
        
        int temp=0;
        for(int i =0; i<100; i++)
        {
            temp+= numbers[number]; //count numbers
            if(temp>=5000)
            {//you found the mid value on this i index
                cout << "The median is " << i << endl;
                
                i = 100; //to break the cycle, you found the median number
                int countNumbers[100][10]; // 100 to store number from 0-99 and the 10 to store the value of each generation cycle.
                

            }
    }
    }
    return 0;
}

line 6, int numbers[100]; //to store numbers from 0 - 99 here you need array size of 10,000


line13, int number = rand() % 10000 + 1;
here you need 0 to 99, but you did 1 to 10,000


line14, numbers[number]=0; //Fill with zeros
what is this ¿ ¡ ? ¿

line17, srand(time(NULL));
you used srand after rand ?

ok, enough for me...

anup: thank you for helping me with some of that. I'm really confused so i appreciate any help i can get

so what you're doing is reading in a file? is there a way to do it without reading in a file?

[anup30]

no, i wrote to file to show the output.
when line7 is deactivated it will show result in your console screen.

[abc456]

thank you so much! i am so thankful to you. does the median formula i had work in this?

[anup30]

what is your median formula?

[abc456]

for(int i =0; i<100; i++)
        {
            temp+= numbers[number]; //count numbers
            if(temp>=5000)
            {//you found the mid value on this i index
                cout << "The median is " << i << endl;
                
                i = 100; //to break the cycle, you found the median number
