# C++ beginner, help for school project

Posts: 1Member
Hello there!

(I know that nobody want to make full new code for another people, but this is all about it, please continue reading)

I am having trouble in school with some basic and easy (not for me) C++ programming.
If you could help me, I need codes for these programs to pass a high school grade. I study IT school, but I study multimedia and presentation, but they want basic programming too and I have no idea what to do with it.

Thanks for any help guys!

Create a program, which determines every prime number in interval <1;100> and then print to screen:
Prime numbers in range 1

A number, n, is prime if and only if it has no divisor between {2,...,rounded square(n)}. I answered a similar question here

here is the code:

``````#include <iostream>
using namespace std;

bool isPrime(unsigned int n)
{
for(unsigned int i=2;i<=n/2;i++)
{
if(n%i == 0)
return false;
}
return true;
}
int main()
{
unsigned int UpperBound = 100;
unsigned int LowerBound = 1;
for(unsigned int i=LowerBound;i<=UpperBound;i++)
if(isPrime(i))
cout<<i<<endl;
return 0;
}
``````
