Decimal to binary

Convert a number to its binary.

Copy the code and paste it in here

#include <iostream>

#include<conio.h>

using namespace std;

void main()

{

int q, r, a, b[16] = { 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 };

int i = 0;

cout << "\nEnter a number between -32768 and 32767....";

cin >> a;

if (a>0)

{

q = a;

}

else

{

q = -a;

b[15] = 1;

}

cout << "\nBinary in 16-bit format ";

for (i = 0; q != 1; i++)

{

r = q % 2;

b[i] = r;

q /= 2;

}

b[i] = 1;

for (int j = 0; j<16; j++)

{

if (j % 4 == 0)

cout << " ";

cout << b[15 - j];

}

_getch();

}

Calculator

This is my Calculator program. In this program you can enter the entire expression instead of only 2 numbers.Try it and comment below.

#include<iostream>

#include<conio.h>

using namespace std;

void main()

{

int a,b;

char c;

system("cls");

cout << "Enter the expression....";

cout << "\nPress '= 'after entering expression....";

cin >> a;

do

{

cin >> c;

switch (c)

{

case '+':cin >> b; a += b; break;

case '-':cin >> b; a -= b; break;

case '*':cin >> b; a *= b; break;

case '/':cin >> b; a /= b; break;

}

} while (c != '=');

cout << a;

_getch();

}
