C / C++ program to print the table for a particular number

Leave a Comment
/* The following C/C++ program will print the table of any number entered. The following program can be extended to print tables for 'n' numbers by inserting the table() function in a loop or making multiple call of it */

Code:
#include<iostream>
#include<conio.h>
using namespace std;
void table (int a)
{
int i=1;
while (i<=10)
{
cout<<a<<"*"<<i<<"="<<a*i<<endl;

/* “fstream" class is used for both reading and writing a file. So we need to copy the contents of a file into another file than we will use “fstream”, it has functions capable of both reading & writing in the file. NOTE: both the text file has to be present initially. */

Code:
#include<iostream>
#include<conio.h>
#include<fstream>
using namespace std;
int main ()
{
fstream a,b;
char ch;
a.open("bunty.txt");
//The file from which the content will be copied
b.open("babli.txt"); //The file to which the content will be copied
while (!a.eof())

//reading from file object 'a'
cout<<ch;
b<<ch;
//writing to file babli.txt
