    printing arrays with concatenation

    for example i want to use 25 arrays with 6 elements each:
    cell1[]={1,2,3,4,5,6}
    cell2[]={7,8,9,10,11}.... until cell25[]
    i want to print the content of a cell depending on its number:
    for example, i typed 1, then it will print the elements inside cell1.
    i don't want to use the if statement coz the code will be very long, i guess. Instead i would like to use concatenation
    is it possible for given a variable for the input as n, can i do this
    Code:
        for(n=1;n<26;n++){
            for(m=0;m<5;m++){
                printf("%d\n",("cell"+n)[m]));
            }   
        }
    in this manner i dont have to write many if statements
    i know there is an error... that's why i need your help...i hope i
    have described my question clearly... thanks..

    Instead of
    Code:
     cell1[]={1,2,3,4,5,6};
    cell2[]={7,8,9,10,11};
    Why not
    Code:
    cells[2][6 ]= {
      {1,2,3,4,5,6},
      {7,8,9,10,11}
    };
    Then nested for loops work just like you want them to.
    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.
