    Smile Basic Programming

    I am trying to Ccate a program that will read from a file, a list of
    any sort(numbers, strings, names, etc. ) store them into an array and print them out in reverse order into an output file. Could someone please get me started?

    1) Look in the FAQ for file I/O
    2) Look up sorting routines
    3) The rest is easy

    Code:
    //open the file
    FILE *fptr = fopen(filename,"r"); if(fptr == NULL) exit(1);
    //read input
    int i_array[20];
    int i=0;
    while(fscanf(fptr,"%d",&i_array[i]) != NULL)
    {
       ++i;
       if(i >= 20) break;
    }
    --i;
    while(i > 0)
    {
       printf("%d\n", i_array[--i]);
    }
    I didn't test this but it should be right or else close to perfect or whatever the hell...
    I compile code with:
    Visual Studio.NET beta2
