C++ Lecture: 8

Lecture 8

Boolean type variables:

             It is range of one byte.

Code:

#include <iostream>

#include <conio.h>

using namespace std;

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

{

 bool i; //Declaring

  i=true; //Initializing

  cout << " This is true : "<< i << endl;

  i=false; //Initializing

  cout << " This is false: "<< i << endl;

  getch();

  return 0;

}

Compile the program Ctrl+F9

      Run program Ctrl+F10

Arithmetic Instruction

Code:

#include <iostream>

#include <conio.h>

using namespace std;

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

{

 int a,b; //Declaring

  a=4; b=5; //Initializing

  cout << "  Addition : "<< a+b << endl;

  cout << "  Subtraction : "<< a-b << endl;

  cout << "  Multiplication : "<< a*b << endl;

  cout << "  Division : "<< a/b << endl;

  cout << "  Modulus : "<< a%b << endl;

  getch();

  return 0;

}

Logical Instruction

Code AND Truth table:

#include <iostream>

#include <conio.h>

using namespace std;

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

{

  bool a,b;

  a=true , b=true; 

  cout << "  True and True : "<< (a & b) << endl;

  a=true , b=false; 

  cout << "  True and False : "<< (a & b) << endl;

  a=false , b=true; 

  cout << " False and True : "<< (a & b) << endl;

  a=false , b=false; 

  cout << " False and False : "<< (a & b) << endl;

  getch();

  return 0;
