      Sp-- tell us about the decrease of space in the pattern like
      ssssss@
      sssss@@
      ssss@@@
      sss@@@@
      ss@@@@@
      s@@@@@@
      Here 's' indicates the decreasing order of space in pattern. Just like sp

    There is no basic difference between the following programs. But when I run these two they show difference shaped pyramids. Can anybody tell me why?
    ................................................................................................
    Programe of Q. NO-5 of this blog:

    #include
    #include
    void main()
    {
    clrscr();
    int num=5,r,c,sp;
    for(r=1;r<=num;r++)
    {
    for(sp=num-r;sp>=1;sp--)
    {
    printf(" ");
    }
    for(c=1;c<=r;c++)
    {
    printf("*");
    }
    printf("\n");
    }
    getch();
    }
    ........
    my programe:

    #include
    #include
    void main()
    {
    clrscr();
    int row, space, star;
    for(row = 1; row<=5; row++)
    {
    for(space = 5-row; space >=0; space--)
    {
    printf(" ");
    }
    for(star = 1; star<=row; star++)
    {
    printf(" * ");
    }
    printf("\n");
