I'm writing a program to calculate the number of prime numbers in a sequence. There's a variable called num that is given and then the program must calculate how many prime numbers there are from 2 (the smallest prime number) to num.

It should be something like that:

Enter a number greater than 1: 7 There are 4 prime numbers between 2 and 7.

This is because 2,3,5 and 7 are prime numbers, a total of 4 numbers.

The code below shows the variable num which is equal to 7, the main function...

How many prime numbers are there in this sequence
