Write a program that inputs fifteen integer values in an array. It finds out all the prime numbers.

Write a program that inputs fifteen integer values in an array. It finds out all the prime numbers stored in an array and displays the result on screen.

So let’s Write Code:

Introduction to C++ Programming | Download and Install Dev C++ Compiler

Let’s build logic First:

Algorithm for code:

• Step 1: Start
• Step 2: Declare an array and variables n, count, d and p
• Step 3: Initialize variable count = 0, p=1, d=2;
• Step 4: Input Numbers from User.
• Step 5: if(arr[n]%d==0 ) set p=0 and break.
• Step 6: if remainder is 1 then Count ++.
• Step 7: Print Prime Numbers
• Step 8: Stop

Write a program that inputs fifteen integer values in an array. It finds out all the prime numbers.

#include<iostream>
using namespace std;
main()
{
int arr[15], n, count = 0, d, p;
for(n = 0;n<=14; n++)
{
cout<<"Enter a value in element "<<n<< " of the array ? ";
cin>>arr[n];
}
for(n = 0;n<=14; n++)
{
p = 1;
for(d = 2; d < arr[n]; d++)
if (arr[n]%d ==0)
{
p = 0;
break;
}
if (p == 1)
{
cout<<arr[n]<<endl;
count++;
}
}
cout<<"\n Prime numbers stored in an array are:"<<count;
}
