Question

Write a C++ program that has an array of 20 integer numbers. It should call a function to initialize the array. Then it should call a function to find the smallest and average of the array.

Answer 1

C++ program:-

#include <iostream>

using namespace std;

void arr_init(int* array1, int items){
for (int i = 0; i < items; i++)
{
cout << "Enter a number: " ;
cin >> array1[i];
cout << endl;
}   
}

void arr_min(int arr[],int items){
int min = arr[0];
int i;
for (i = 1; i < items; i++)
{
if (min > arr[i])
min = arr[i];
}

cout << "The smallest number in the list is " << min << endl;
cout << endl;

}

void arr_avg(int arr[],int items){
double sum=0.0;
int i;
for (i = 0; i < items; i++)
{
sum=sum+arr[i];
}
double avg = sum/(double)items;

cout << "The average of elements in the list is " << avg << endl;
cout << endl;

}

int main() {
int arr[20];
arr_init(arr,20);
arr_min(arr,20);
arr_avg(arr,20);
}

Output:-

I performed it for 5 numbers
