Good evening my dear, My question is about repetition (while and for). In an exercise I want to print the numbers from one to 10. But I want to group them 2 by 2 or 3 by 3 to follow this logic:

123

456

789

...

Thank you very much for your attention. Att,

c

Hello, your question is not so clear, try to present a piece of code you have.

Here is an algorithm that solves the question (according to what I understand of your question) grouping it by 2, and when it arrives at 10 it restarts the count:

#include<stdio.h>

int main(void)
{
    int i = 0, j = 0, aux = 1;
    for (i = 1; i <= 10; i++){
        printf("%d. ", i);
        for (j = aux; j <= (aux + 1); j++){
            printf("%d ", j);
        }
        aux = j;
        if(aux > 9) aux = 1;
        printf("\n");
    }
    return 0;
}
