C – List All Prime Numbers Between 1 to N

Write a C Program to List All the Prime Numbers Between 1 to N. Where N is the maximum number entered by the user.

#include<stdio.h>
int main()
{
        int i, num, maxNumber;
        int isPrime;

        printf("Enter max number: ");
        scanf("%d", &maxNumber);

        for (int num = 2; num <= maxNumber; num++)
        {
                isPrime = 1;
                for (int i=2; i <= num/2; i++)
                {
                        if ( num % i == 0)
                        {
                                isPrime = 0;
                                break;
                        }
                }

                if ( isPrime == 1 )
                        printf("%d, ", num);
        }
}

#include<stdio.h>

int main()

{

int i, num, maxNumber;

int isPrime;

printf("Enter max number: ");

scanf("%d", &maxNumber);

for (int num = 2; num <= maxNumber; num++)

{

isPrime = 1;

for (int i=2; i <= num/2; i++)

{

if ( num % i == 0)

{

isPrime = 0;

break;

}

if ( isPrime == 1 )

printf("%d, ", num);

}

Compile and run the program.

Enter max number: 50
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47,
