How can I use a counting loop to calculate multiples of a number?

Question

I am working on some homework and my task is to write a program in C that uses a loop that counts from 1 to 10 and use the counter of that loop to calculate the multiples up to 5. I have the counting loop created that correctly counts to 10, but where I am stuck at the moment is on the second part of the task. I attempted to create a new loop, but it's not working the way that I would like it to.

#include <stdio.h>

int main (void) {
    int counter = 1;

    // heading
    puts("Number\t 1st\t 2nd\t 3rd\t 4th\t 5th");

    // loop that counts to 10
    while (counter <= 10) {
        printf("%d\n", counter);
        counter++; // adds +1 to the counter
    }

    // stuck on this part
    // loop that attempts to take the 10 numbers from prior loop and display their multiples up to 5 times
    while (counter <=10) {
        printf("%d", counter);

        counter = counter * 1;
        counter = counter * 2;
        counter = counter * 3;
        counter = counter * 4;
        counter = counter * 5;
    }
}

This is what I am wanting it to look like:

You don't want to do this:

    printf("%d", counter);

    counter = counter * 1;
    counter = counter * 2;
    counter = counter * 3;
    counter = counter * 4;
    counter = counter * 5;

You're multiplying your counter by 1*2*3*4*5 = 120 every iteration! Instead, you want to keep your counter simply going 1, 2, 3, ... and directly print the multiples:

int counter = 1;

while (counter <= 10) {
    printf("%d\t %d\t %d\t %d\t %d\t %d\n",
           counter * 1,
           counter * 1,
           counter * 2,
           counter * 3,
           counter * 4,
           counter * 5);

    counter++;
}
