Write a C++ program to accept a number and if it is less than 10 then print its square value.

Q20. Write a C++ program to accept a number and if it is less than 10 then print its square value.

Solution:

#include<iostream.h> //standard input/output header file

#include<conio.h> //for clrscr()

 

int main()

{

int a;

 

clrscr(); //for clearing the screen

 

cout<<“\n Enter a number: “;

cin>>a;

 

a<10? cout<<“\n The square of number is “<<a*a<<“.” : cout<<“\n The number is “<<a<<“.”;

 

getch(); //holds the screen until any key is pressed

return 0; //makes main() finish

}

 

OUTPUT:

CASE 1:

 

Enter a number: 9

 

The square of number is 81.

 

CASE 2:

Enter a number: 11

 

The number is 11.
