Write a program that generates random numbers between 1 and 10 and fill an array of size 20 with them. Have your program sort the array then output in order the number of occurrences of each random number generated. Use the STL sort function to sort your array.

How to use the STL sort:
#include
...
int a[20]
...
sort(a,a+20);
Example Output:
This program generates random numbers and tabulates the results
Original List Sorted:

a[ 0] 1
a[ 1] 1
a[ 2] 1
a[ 3] 2
a[ 4] 2
a[ 5] 3
a[ 6] 6
a[ 7] 6
a[ 8] 6
a[ 9] 7
a[10] 8
a[11] 8
a[12] 8
a[13] 9
a[14] 9
a[15] 9
a[16] 9
a[17] 10
a[18] 10
a[19] 10

N Count
1: 3
2: 2
3: 1
4: 0
5: 0
6: 3
7: 1
8: 3
9: 4
10: 3
Try Again? (1 = yes, 0 = exit)

Answer:

C++ Program:

#include <iostream>
#include <algorithm>
#include <stdlib.h>
#include <time.h>

using namespace std;

int main()
{
int a[20];
int i, j, k=0, cnt=0;
int freq[10] = {0};

//Initializing random seed
srand (time(NULL));

//Generating random numbers
for(i=0; i<20; i++)
{
a[i] = (rand() % 10) + 1;
}

//Sorting array
sort(a, a+20);

//Printing sorted array
for(i=0; i<20; i++)
{
cout << "a[" << i << "] " << a[i] << endl;
}

//Number of occurrence of each number
for(i=1; i<=10; i++)
{
//Iterating over array
for(j=0; j<20; j++)
{
//Updating frequency
if(a[j]==i)
{
freq[i-1] += 1;
}
}
}

//Printing results
for(i=1; i<=10; i++)
{
cout << endl << i << ": " << freq[i-1];
}
cout << endl;

return 0;
}
