C program to copy contents of one file in to another file.

copyfile.cpp

#include <fstream>

#include <iostream>

int main()

{

 string line;

 ifstream ini_file{

 "original.txt"

 };

 ofstream out_file{ "copy.txt" };

 if (ini_file && out_file) {

 while (getline(ini_file, line)) {

 out_file << line << "\n";

 }

 cout << "Copy Finished \n";

 }

 else {

 printf("Cannot read File");

 }

 ini_file.close();

 out_file.close();

 return 0;

}

copyfile.c

#include<stdio.h>
#include<conio.h>
void main(){
FILE *fp1,*fp2;
char ch;
clrscr();
fp1=fopen("abc.txt","r+");
fp2=fopen("xyz.txt","w+");
if(fp1==NULL || fp2==NULL){
printf("opration failed!!\n");
getch();
exit(0);
}
while(ch != EOF){
ch=fgetc(fp1);
fputc(ch,fp2);
}
getch();
fcloseall();
}

First create a file named "abc.txt" and write contents of it then save it in relative folder like BIN . After that run this program.
