###### One Dimensional Array - Question 4

In this question, we will see how to input 10 numbers in a one dimensional integer array and print only the prime numbers from it in C++ programming. To know more about one dimensional array click on the one dimensional array lesson.

Q4) Write a program in C++ to input 10 numbers in a one dimensional integer array and print only the prime numbers from it.

A prime number is a number which is divisible by 1 and itself. Example: 13, 17, 19, etc.

#### Program

``````#include <iostream>
#include <conio.h>

using namespace std;

int main()
{
int a[10], i,j,c=0;

cout<<"Enter 10 numbers\n";
for(i=0; i<10; i++)
{
cin>>a[i];
}

cout<<"\nPrime Numbers\n";
for(i=0; i<10; i++)
{
c=0;
for(j=1; j<=a[i]; j++)
{
if(a[i]%j==0)
{
c++;
}
}

if(c==2)
{
cout<<a[i]<<" ";
}
}
return 0;
}``````

#### Output

```Enter 10 numbers
5
12
18
23
17
45
93
62
7
54

Prime Numbers
5 23 17 7        ```
