Given below is a program for a prime number test using C++:
You can however write the code in a different way. This is just a sample.

Open C++
Write the code:

#include <stdio.h>
#include <conio.h>
void main ()
{
int half,x,state,temp;
printf ("Enter the number\n");
scanf ("%d",&x);
half=x/2;
state=1;
temp=2;
while (state!=0&&temp<=half)
{if (x%temp==0)
{state=0;}
else {++temp;}
}
if (state==0)
{printf ("\n%d is not prime\n",x);}
else {printf ("\n%d is prime\n",x);}
}

Run the code.
It works.
To save, use extension .cpp
