File Handling in C
File Handling in C:- file handling is a way of handle the file . before knowing about file handling we have to know what is file.
what is file
File is a data structure ( sometimes also called as data types ) that can be use to store any data in it permanently .
In programming a file is handle using some file pointer of type ‘ File ‘ ( which is a data structure define as files in standard library ).
To use any file for reading , writing and for any other purpose usually following steps perform in sequence :-
1) Create a Pointer to the file :- File *fp;
#include<stdio.h> int main() { FILE *fp1,*fp2; char ch; fp1= fopen("input.txt", "r"); fp2= fopen("ouput.txt", "w"); if(fp1==NULL || fp2==NULL) printf("Error\n"); else { //logic to copy while((ch==fgetc(fp1))!=EOF) { fputc(ch,fp2); } fclose(fp1); fclose(fp2); } return 0; }
