Thread: C File I/O

Hi all, I'm learning C for the first time (first time learning any programming language). I'm currently going through the tutorial on this site. After reading the tutorial on file I/O I've been trying a few things out.
I'm trying to find a way of asking the user for an input, and then using this input to name a file.

Originally I had:

Code:

#include<stdio.h>

int main(){
FILE *fp;
fp=fopen("d:\\name_of_file.txt","w");
fprintf(fp, "this is text printed in the file");
getchar();
return 0;
}

Then i want to make this something like the following:

Code:

#include<stdio.h>

int main(){
char x[20];
FILE *fp;
printf("Please enter a name for the file...\n");
fgets(x, 20, stdin);
fp=fopen("d:\\name_of_file.txt","w");           //here i want x to be the name of the file 
fprintf(fp, "this is text printed in the file");
getchar();
return 0;
}

Is there a way of doing something like :

Code:

fp=fopen("d:\\%c",x,"w");

Thanks for any help.
