Question

write a c++program to create an array and insert and display the element​

Answer 1

Following C++ program ask to the user to enter array size, then ask to the user to enter array element, then ask to the user to enter element or number to be insert, then at last it will ask to the user to enter the position (index number) where he or she want to insert the desired element in the array, so this program insert the desired element and display the new array on the screen after inserting the element:

/* C++ Program - Insert Element in Array */

#include<iostream.h>

#include<conio.h>

void main()

{

clrscr();

int arr[50], size, insert, i, pos;

cout<<"Enter Array Size : ";

cin>>size;

cout<<"Enter array elements : ";

for(i=0; i<size; i++)

{

cin>>arr[i];

}

cout<<"Enter element to be insert : ";

cin>>insert;

cout<<"At which position (Enter index number) ? ";

cin>>pos;

// now create a space at the required position

for(i=size; i>pos; i--)

{

arr[i]=arr[i-1];

}

arr[pos]=insert;

cout<<"Element inserted successfully..!!\n";

cout<<"Now the new array is : \n";

for(i=0; i<size+1; i++)

{

cout<<arr[i]<<" ";

}

getch();

}

Answer 2

Explanation:

#include<iostream>

using namespace std;

int main ()

{

int arr[10], n, i, sum = 0, pro = 1;

cout << "Enter the size of the array : ";

cin >> n;

cout << "\nEnter the elements of the array : ";

for (i = 0; i < n; i++)

cin >> arr[i];

for (i = 0; i < n; i++)

{

sum += arr[i];

pro *= arr[i];

}

cout << "\nSum of array elements : " << sum;

cout << "\nProduct of array elements : " << pro;

return 0;

}
