Beginner: I/O using .txt files

[RyanLeonard]

Hello, I am writing a program to read characters from a txt file, but initially asking the user via the console to input the file name. this is what i've come up with so far but in unsure how to declare the file name at the pointer as a user in putted value.

#include<stdio.h>

 int main(void)
 {
	char buffer[256];
	char file[14];

	printf("Please enter the file name you want to read: ");
	scanf("%s \n", &file);

    FILE *file_pointer=NULL;
	file_pointer=fopen("%s", "r");

	while (fgets(buffer,256,file_pointer));
	{
		printf("%s",buffer);
	}
 }

Regards
Ryan

You need to look up sprintf().

Also, don't forget that main returns 0 at the end.

#include<stdio.h>

 int main(void)
 {
	char buffer[256];
	char file[14];

	printf("Please enter the file name you want to read: ");
	scanf("%13s", file); /* read max. 13 chars -> no buffer-overrun here */

        FILE *file_pointer;
	file_pointer=fopen(file, "rt"); /* rt (read text) is the same as r, but more readable */
        if( !file_pointer ) {perror(file); exit(1);} /* error-handling and error info to console */

	while (fgets(buffer,256,file_pointer));
	{
		printf("%s",buffer);
	}
        fclose(file_pointer);
 }

You don't quite seem to understand the idea of helping someone along the way instead of providing the complete solution. If I were an admin I would ban you for trolling.

I agree with Claudiu.
Nobody learns a thing when you just feed them the answer
Moreover, it goes agains the educational nature of these forums.

Unfortunately, you have just stepped on a mine. A gazillion people will now jump on this thread saying that the purpose of these forums is not to be educational but to answer questions.

Thanks for the help, although it seems that the only thing that kept my code from doing what i wanted it to do was the '\n' on the 9th line after the scanf function

Kind regards
Ryan

So that's what that loud click was? LOL.
