    This is a simple idea. Have you tried thinking about double for loops? You will need it here. I don't want to tell you the solution, because it is better to learn.
    Code:
    for(...;...;...) {
       for(...;...;...) {
          // some print statement
       }
    }

    My question is what the hell have you been up to in the past week that you ask the same question with the same lack of effort?
    need help
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    {
       for(j=i;j>0;j--)
          { 
          printf("%d",i);.

    Perhaps you should practice getting ONE loop to compile first, before trying two.

    Say output
    1
    2
    3
    4
    5

    Surely you could do that?

    Maybe?

    If you're supposed to be C++ then copying and pasting someone else's program is not going to earn you any brownie points with whoever your educator is - especially when it is not completely C++ and does not work.

    Now to echo Salem, what have YOU done to try and solve the problem (trawling the Internet for 'close but not cigars' code does not count) - have YOU written any code yourself?
