    Deleting element from an array problem

    Hey guys!,

    I am trying to remove a user specified element from the display of an array. I know that this doesn't take it out of the array, but I figure that if I get this it would be the same process copying it to a temp array and then back.

    Code:
    printf("Please enter number to delete");
       scanf("%d",&d);
       
       printf("\n\n\nModified list:");
       
       for (i=0;i<x;i++) 
       {   
           if (i = d) 
           {
                 i = i+1;
           }
           else 
           {
           printf("%s",words[i]);
           }
    }

    > if (i = d)
    Perhaps == instead of =

    Didn't your compiler warn you?

    Are you using a compiler which is capable of warning you?

    You need not start from 0, if the user inputs the number into the variable d, just start out with that number itself.
    Code:
    for(i=d;i<MAX-1;i++)
    array[i]=array[i+1];
    Code:
    >+++++++++[<++++++++>-]<.>+++++++[<++++>-]<+.+++++++..+++.[-]>++++++++[<++++>-] <.>+++++++++++[<++++++++>-]<-.--------.+++.------.--------.[-]>++++++++[<++++>- ]<+.[-]++++++++++.

    Hmm.. but doesn't that just start from the element they entered? I want to be able to display all the elements as if it were removed. such as :

    1.box
    2.shoe
    3.red
    4.crayon

    user selects to delete red from the display, new display should look like this:

    1.box.
    2.shoe
    3.crayon

    I hope I'm making this clear enough.

    I appreciate any help you give me.

    just replace this
    Code:
    array[i]=array[i+1];
    by this
    Code:
    strcpy(array[i],array[i+1]);
    This is valid considering that you are using a 2d char array to store the different strings.
    Code:
    >+++++++++[<++++++++>-]<.>+++++++[<++++>-]<+.+++++++..+++.[-]>++++++++[<++++>-] <.>+++++++++++[<++++++++>-]<-.--------.+++.------.--------.[-]>++++++++[<++++>- ]<+.[-]++++++++++.

    And you should set array[0] to something, too.

    Code:
    if (i = d)
    ->
    Code:
    if (i == d)
