Thread: while loop, triangular number

Simple program, what is in comment section, for loop, question out of book to be made into a "while" loop. First number works after executing program, but never is updated to 2 through 5th entry. Thanks!

Code:

#include <stdio.h>

int main(void)
{
    int n, number, triangularNumber, counter;

    /*
    for(counter = 1; counter <= 5; ++counter)
    {
        printf("What triangular number do you want? ");
        scanf("%i", &number);

        triangularNumber = 0;

        for( n = 1; n <= number; ++n)
            triangularNumber += n;

        printf("Triangular number %i is %i\n\n", number, triangularNumber);

    }
    */


    counter = 1;
    n = 1;
    triangularNumber = 0;

    while (counter <= 5)
    {
        printf("What triangular number do you want? ");
        scanf("%i", &number);
        while (n <= number)
        {
            triangularNumber += n;
            n++;
        }
        printf("Triangular number %i is %i\n\n", number, triangularNumber);
        ++counter;
    }

    return 0;
}

Here's working code, thanks Salem!

Code:

// 4_5_5.c

#include <stdio.h>

int main(void)
{
	int n, number, triangularNumber, counter;

	/*
	for(counter = 1; counter <= 5; ++counter)
	{
		printf("What triangular number do you want? ");
		scanf("%i", &number);

		triangularNumber = 0;

		for( n = 1; n <= number; ++n)
			triangularNumber += n;

		printf("Triangular number %i is %i\n\n", number, triangularNumber);

	}
	*/


	triangularNumber = 0;
	counter = 1;
	while (counter <= 5)
	{
		n = 1;
		triangularNumber = 0;
		counter++;
		printf("What triangular number do you want? ");
		scanf("%i", &number);
		while (n <= number)
		{
			triangularNumber += n;
			++n;
		}

		printf("Triangular number %i is %i\n\n", number, triangularNumber);
	}

	return 0;
}
