Hello, Will you please provide an example of how I can implement the following requirement into the existing code I have?
The function I am trying to create is:
In C++, develop a function to format the output for a list of prime numbers. The function must accept two whole numbers: a sequence number and the prime number. The prototype for this function should be string formatPrime(int sequence, int prime);. The function must return a string formatted as Prime #6 = 13.
This is the code I have so far:
#include "pch.h"
#include
#include
using namespace std;
bool isPrime(int number);
int main()
{
int number, n, count, primenum = 0, num= 2;
bool flag;
do
{
cout << "Enter a number between 30 and 2000" << endl;
cin >> n;
cout << endl;
}
while (n < 30 || n > 2000);
cout << "2" << " ";
while (primenum < n - 2)
{
num++;
count = 0;
for (int j = 2; j < num; j++)
{
if (num % j == 0)
{
count++;
break;
}
}
if (count == 0)
{
cout << num << " ";
primenum++;
}
}
cout << "Test any number to see if it is prime. If it is, the output will show true." << endl;
cout << "If it is not a prime number the output will show false " << endl;
cin >> number;
flag = isPrime(number);
if (flag == true)
cout << number << " is a prime number. " << endl;
else
cout << number << " is not a prime number. " << endl;
return 0;
}
bool isPrime(int number)
{
bool flag = true;
for (int i = 2; i <= number / 2; ++i) {
if (number % i == 0) {
flag = false;
break;
}
}
return flag;
}
