Question

I’m probably missing something obvious, but every time I write to a file, the inputted text is on the second line of the document when I open it. What is causing this?

#include <stdio.h>

int main()
{
    char c;
    char filename[100];
    FILE *fp;

    printf("Type the name of the file to write to followed by enter: \n\n");

    scanf("%[^\t\n]s", filename); 

    fp = fopen(filename, "w");

    printf("\n\nEnter the text you wish to write to this file: \n\n");

    while ((c = getchar()) != EOF)
    {
        putc(c, fp);
    }

    return 0;
}

Answer 1

You’ve told scanf not to eat any \n characters, so there will still be one sitting in the input buffer when you start the loop with putc getchar.

One solution would be to precede the loop with a call to putc getchar to eat the \n.
