Question

In C++ cout<<"" << NO std:cout

Write a function that accepts two integer arrays of the same size. The first array will have numbers and the second array will be filled out inside the function. The function should find all numbers in the array that are greater than or equal to the average and fill out the second array with these numbers. You need to design the function.Comments as well please because i am super confused. Thank you!

Answer 1

#include<iostream>
using namespace std;

void fillArray(int arr1[],int arr2[],int arr_size)
{
int cnt=0;
double avg,sum;
for(int i=0;i<arr_size;i++)
{
sum+=arr1[i];
}

avg=sum/arr_size;
//assigning the second array
for(int i=0;i<arr_size;i++)
{
if(arr1[i]>=avg)//condition to check average
{
arr2[cnt]=arr1[i]; //assigning value to array 2
cnt++;
}
}

//printing seond array
cout<<"Second array is: ";

for(int i=0;i<cnt;i++)
{
cout<<arr2[i]<<" ";
}

}

int main()
{
int arr_size;
cout<<"Enter the size of array: ";
cin>>arr_size;
int arr1[arr_size],arr2[arr_size];
cout<<"Enter the element:\n";
for(int i=0;i<arr_size;i++)
{
cin>>arr1[i];
}
fillArray(arr1,arr2,arr_size);

}
