    need to make an array
    need to make a for loop, where 40 is the max
    need to make a break out of the for loop if -1 is entered
    need to make another for loop, that stops at the last input from previous loop

    get some code down, so we can help further

    Code:
    int n[40]={0},i,j,top;
    for(i=0; i<40 && n[i]!=-1; i++)
      scanf("%d",&n[i]);
    top = i-1;
    for(i=0;i<=top;i++)
    {
       for(j=0;j<n[i];j++)
         printf("|");
       printf("\n");
    }
