    Cool read data in files

    Hello

    my data is being written to a data file like this.

    3.456 3.456 2.345 2.345
    3.456 6.788 9.896 9.984

    ... from left to right.

    I want to read the data in another program column wise.

    Like

    fscanf(fp,"%f, %f, %f, %f",&v1,&v2,&v3,&v4);

    having v1 hold the first column, v2 hold the second and so on need a little help.

    I am displaying it in GL but it is spitting it out fast like a counter, how to slow it down.

    Thanks

    D

    Read the whole file into a 2d array and then display it however you want to.

    If you are uncomfortable with 2d arrays, read the data into a single array and define colums as array[i] and array[i+4].

    If the data stored in the file is delimitted with a spce, why are you reading it with fscanf() with a command as a delimiter? Remove the commas in your fscanf().

    Why do you need this in C though? You might just use a ;, if you really need it.
