    Variable strings

    I have an array of strings char string[n][MAX_FILE_NAME] and in each string I want to initialize it with the name of a bunch of files I have. string[0] should be "txt_0", string[1] = "txt_1" etc.

    But I don't know how to construct the string names beginning with txt_ and ended in the int counter value.

    Use a loop containing something like
    Code:
       sprintf(string[i], "txt_%d", i);
    Right 98% of the time, and don't care about the other 3%.

    If I seem grumpy or unhelpful in reply to you, or tell you you need to demonstrate more effort before you can expect help, it is likely you deserve it. Suck it up, Buttercup, and read this, this, and this before posting again.

    You probably can use snprintf. Something like this might work

    Code:
    snprintf(str, MAX_FILE_NAME, "txt_%d", 1);
