Files are created and manipulated to store permanent data needed for a program. In C language, text files can be created and processed using file I/O functions. In the following program, we see how to create a new text file and open the created file and display the contents of the file on the screen.
//Program to create a text file
#include<stdio.h>
#include<conio.h>
main()
{
FILE *f1;
char c;
clrscr();
f1=fopen("sample.txt","w");
printf("Enter text. Press ctrl+z to stop input\n");
printf("----------------------------------------------\n");
while ((c=getchar())!=EOF)
fputc(c,f1);
fclose(f1);
printf("The content of the file\n");
printf("--------------------------\n");
f1=fopen("sample.txt","r");
while((c=getc(f1))!=EOF)
putchar(c);
fclose(f1);
getch();
}
/*
OUTPUT
-------
Enter text. Press ctrl+z to stop input
---------------------------------------------
This program creates a text file.
The input is read from the keyboard.
To stop getting input press ctrl+z.
The content of the file
--------------------------
This program creates a text file.
The input is read from the keyboard.
To stop getting input press ctrl+z.
