Re: To write first 100 prime numbers in c++ program.

Hey,

Why dont you use a for loop?

Code:
for ( int n = 0, n >= 100, n++)
here it is:
Code:
#include <iostream>
using namespace std;
 
int main() {
 
    for (int n = 3; n <= 100; n++) {
        // TO DO
    }
 
    return 0;
}
I hope this helps.

Re: To write first 100 prime numbers in c++ program.

Hey I have the code but its for java. The logic is same.
Try it. It give you first 100 prime numbers.
Code:
public class whileprime
{
    public static void main(String args[])
{
    int num = 4;
    int count = 0;
    System.out.println("First 100 Prime Numbers: ");
    System.out.println("1");
    System.out.println("2");
    System.out.println("3");
    while(count < 100)
        {
            num++;
            if(num % 2 != 0)
                {
                    int dv = 3;
                    while((num % dv != 0)&&(dv <= ((num - 1) / 2)))
                        {
                            dv++;
                        }
                            if(num % dv != 0)
                                {
                                    count++;
                                    System.out.println(num + "         ");
                                   
                                }
                }
        }


}


}
I hope this helps you.

Re: To write first 100 prime numbers in c++ program.

Here is a code to find out prime numbers between 1 - 100 :

Code:
void main()
{
int i,number=1;
clrscr();
while(number<=100)
     {
     i=2;
     while(i<=number)
         {
         if(number%i==0)
         break;
         i++;
         }
     if(i==number)
     printf("\n%d is Prime",number);
     number++;
     }
getch();
}
Is this what you need?
