File Management in C

Simple File Management

Using Command Line Argument

#include "stdio.h"

#include "conio.h"

#include "stdlib.h"

void main()

{

FILE *fp1,*fp2;

char ch;

clrscr();

//Open File 1 in Read Mode

fp1=fopen(“D:\abc.txt”,"r");

//Open File 2 in Write Mode

fp2=fopen(“D:\xyz.txt”,"w");

//Read data from File 1

ch=getc(fp1);

while(ch!=EOF)

{

printf("%c",ch);

//Write data to File 2

putc(ch,fp2);

//Read data From File 1

ch=getc(fp1);

}

fclose(fp);

fclose(fp1);

getch();

}

#include "stdio.h"

#include "conio.h"

#include "stdlib.h"

void main(int argc,char *argv[])

{

FILE *fp1,*fp2;

char ch;

clrscr();

//Open File 1 in Read Mode

fp1=fopen(argv[1],"r");

//Open File 2 in Write Mode

fp2=fopen(argv[2],"w");

//Read data from File 1

ch=getc(fp1);

while(ch!=EOF)

{

//Write data to File 2

//Read data From File 1

ch=getc(fp1);

}

fclose(fp);

fclose(fp1);

getch();
