Q21. Write a C++ program to accept a number and if it is less than 50 and greater than 20 than 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<50&&a>20? 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: 45
The square of number is 2025.
CASE 2:
Enter a number: 78
The number is 78.
