A menu driven program to convert a decimal number to binary octal and hexadecimal?

Answer 1

#include<iostream>

#include<conio.h>

using namespace std;

class conv

{

int x,b,r,arr[20],ch;

public:

void get()

{

cout<<"ENTER THE VALUE TO BE CONVERTED:(IN DECIMAL):";

cin>>x;

cout<<"ENTER BASE TO WHICH U WANT TO CONVERT:(UP TO BASE 18):";

cin>>b;

}

void convert();

};

void conv :: convert()

{

int i=0,j;

cout<<"-----------------CONVERSION PROGRAM------------------------\n";

while(1)

{

cout<<"-----------------------------------------------------------\n";

cout<<"1.CONVERT FROM DECIMAL TO OTHER\n2.QUIT\n";

cout<<"------------------------------------------------------------\n";

cout<<"ENTER UR CHOICE:";

cin>>ch;

switch(ch)

{

case 1:

get();

cout<<"IN BASE "<<b<<":";

while(x>0)

{

r=x%b;

arr[i]=r;

x=x/b;

i++;

}

for(j=i-1;j>=0;j--)

cout<<"A";

else if(arr[j]==11)
