**Introduction**

This is program to find the prime numbers form the array list. The program is given below. The program is not extendable. Go enjoy the program. Lets begin…….

**Program to find prime number from array list.**

#include<iostream.h>

#include<conio.h>

void main()

{

//clear the screen.

clrscr();

//declare variable type int

int a[10],i,j,f,m;

//Input the two numbers save them in arrays.

//Here for loop is used to input multiple numbers in array.

for(i=0;i<5;i++)

{

cout<<“Enter the no.”<<endl;

cin>>a[i];

}

//Draw a line for good looking program.

cout<<“————————————“<<endl;

cout<<“Prime numbers are “<<endl;

//Print the array.

for(i=0;i<5;i++)

{

f=0;

for(j=2;j<a[i];j++)

{

m=a[i]%j;

if(m==0)

{

f=1;

break;

}

}

if(f==0)

cout<<a[i]<<endl;

}

//get character

getch();

}

**Output**

Enter the number

2

Enter the number

3

Enter the number

4

Enter the number

5

Enter the number

Prime numbers are

2

**How does it work**

- You enter the number.
- The number is saved in respective array.
- The numbers from arrays are taken and tested if prime number.
- The prime numbers are printed.

**Extending it**

The program cannot be extended.

**Explanation.**

- Include ‘iostream.h’ and ‘conio.h’ files.
- Add void main.
- Start program by first clearing the screen.
- Declare the variables as int (name them as you want.)
- Add the cout and cin of array.
- Add for loop to find prime number.
- Print the prime number.

**At the end**

You learnt creating the C++ program of Finding prime numbers from array. So now enjoy the program.
