Homework Help: C programming question

  1. Mar 22, 2013 #1
    How do you print text after a scanf statement on the same line? This is what i need the output to look like:

    Enter a number here: _%

    The _ is the scanf waiting for input. Now when i write the code like this:

    printf("Enter a number here: ");
    scanf("%d", &x);
    printf("%\n");

    It wont put the % sign until after i input a value. How should i rewrite this to achieve what I need? thanks in advance!

    You can only do that if you use ansi screen codes to reposition the cursor after you've written the prompt line:

    These work only if your terminal window supports them and if its been enabled. I've used them in my awk scripts a lot.
