Question

The main(int argc, char *argv[]) function will perform the following:
• Evaluate whether value in argc is greater or equal to 3.

• If it is not, then print the following message: Incorrect number of arguments -

please call with assignment min max
where assignment is the name of your executable and min/max define the range of numbers for your array.

• If argc is ≥ 3 convert the values for min and max into integers and store them in suitable variables.

• Make sure that min ≤ max - if not, swap both values. • Create an integer array with 10 elements, call fillArray(...) to fill your array with random values in range min to max (both inclusive). Call printArray(...) to display the content of your array to the screen.

• Repeat the previous item with an array of size 50.

Given below is the code for teh question. Please do rate the asnwer if it helped. Thank you

#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
void fillArray(int *arr, int n, int min, int max);
void printArray(int *arr, int n);
int main(int argc, char *argv[]){
   if(argc < 3){
       cout << "Incorrect number of arguments" << endl;
       cout << "Usage: " << argv[0] << " min max" << endl;
       return 0;
   }
   srand(time(0));
   int min = atoi(argv[1]);
   int max = atoi(argv[2]);
   if(max < min) //to swap?
   {
       int temp = min;
       min = max;
       max = temp;
   }
  
   int *arr = new int[10];
   cout << "Creating an array of size 10" << endl;
   fillArray(arr, 10, min, max);
   printArray(arr, 10);
  
   delete []arr;//deallocate memory
   cout << "\nCreating an array of size 50" << endl;
   fillArray(arr, 50, min, max);
   printArray(arr, 50);
   return 0;
}

void fillArray(int *arr, int n, int min, int max){
   for(int i = 0; i < n; i++)
       arr[i] = min + rand() % (max - min + 1);
}
void printArray(int *arr, int n){
   for(int i = 0; i < n; i++){
       if(i % 10 == 0) // pring newline for every 10 numbers
           cout << endl;
       cout << arr[i] << " ";
   }
   cout << endl;
}
