Program to enter an integer and find out if it is even or odd

#include 

#include 

void main()

{

clrscr();

int x;

cout << "Enter an integer : ";

cin>>x;

if(x%2==0)

cout << "The number " << x << " is even.";

else

cout << "The number " << x << " is odd.";

getch();

}

Output

The number 86 is even.

Program to enter two integers and print the quotient and remainder

#include 

#include 

int main()

{

clrscr();

int x,y,quotient,remainder;

cout << "Enter 2 integers greater than 0 : ";

cin>>x>>y;

quotient=x/y;

remainder=x-(quotient*y);

cout << "Quotient of " << x << " & " << y << " = " << quotient << "\n";

cout << "Remainder" << " = " << remainder << "\n";

getch();

return 0;

}

Output

Quotient of 23 & 4 = 5

Remainder = 3
