    I'm not really sure what you mean. I'd use three variables for that, one containing the current number, one containing the number of numbers in the current line, and the third would be a loop from 0 to the second. Probably something like:
    Code:
    int i=1, j=1;
    for (k=0; k<j; k++)
      printf("%d ",i++);
    printf("\n");
    j++;

Probably something along the following lines:
    Code:
    int i=1, j=1
    for k=0..j
      printf(i++)
    printf("\n")
    j++

    xpi0t0s has already answered your question.
    To recap, something like this:
    Code:
      int column, line, n = 1;
      for (line = 0; line < number_of_lines; ++line) {
        for (column = 0; column <= line; ++column)
          printf ("%3d ", n++);
        printf ("\n");
      }

    Get someone else to do it. Programming is HARD.

    Have a look at my argument...it's similar, except for the display is in a equilateral triangular fashion....
    Code:
    #include<stdio.h>
    #include<conio.h>
    
    #define m 4
    
    void main()
    {
    int i,j,c,n=1,p=m;
    for(i=0;i<m;i++)
    {
    for(c=p;c>=0;c--)
    {
    printf(" ");
    }
    for(j=0;j<=i;j++)
    {
    printf("%d ", n);
    n++;
    }
    printf("\n");
    p--;
    }
    getch();
    }
    
    Cheers....
