C Programs using File Operations

We can open and use a number of files at a time. This number however depends on the system we use.

/* C Program to create a file and write some data the file */

#include <stdio.h>

#include <conio.h>

main()

{

FILE *fp;

char stuff[25];

int index;

fp=fopen("FIRST", "w"); /* open for writing */

strcpy(stuff, "This is an example line.");

for (index = 1; index <= 5; index++)

fprintf(fp, "%s Line number %d\n", stuff, index);

fclose(fp); /* close the file before ending program ending_program */

}

OUTPUT

C:\TC\BIN> type first

This is an example line. Line number 1

This is an example line. Line number 2

This is an example line. Line number 3

This is an example line. Line number 4

This is an example line. Line number 5

Explanation: After executing the program, go to the dos prompt and go to the respective library, in this case C:\TC\BIN> and type the file name as above. Please save the above C program as CFEXA.C, since this can be used for next program
