The keyboard shortcut to bring up print on windows is ctrl+P, for Mac it's cmd+P.
Unless, you mean print screen - for that, there is a button that should say prt sc on your keyboard for windows, and for Mac, it's cmd <span>+ ctrl + shift + 3 to save to clipboard (or don't hold down the ctrl to save to your desktop).</span>

// Program starts here
#include<iostream>
using namespace std;
int main ()
{
// Declare Variable
int selection;
// Prompt user to make a selection of medium between air, water or steel.
cout<<"Make Selection"<<'\n'<<"Press 1 for Air"<<'\n'<<"Press 2 for Water"<<'\n'<<"Press 3 for Steel";
cin>>selection;
// Check for entry
if(selection == 1) {
cout<<"You selected Air"<<'\n';
cout<<"The distance travelled by sound wave in air is 1,125 feet in 1 second";
}
else if(selection == 2) {
cout<<"You selected Water"<<'\n';
cout<<"The distance travelled by sound wave in water is 4859 feet in 1 second";
}
else if(selection == 3) {
cout<<"You selected Steel"<<'\n';
cout<<"The distance travelled by sound wave in steel is 19554 feet in 1 second";
}
else

Answer:
public static void quad(double a, double b, double c) {
double D = (Math.pow(b, 2)) - (4 * a * c);
if (D<0){
System.out.println("no real solutions");
}
}
Explanation:
The code snippet above implements the function in Java programming language
As required by the question, the line double D = (Math.pow(b, 2)) - (4 * a * c); evaluates b squared" - 4ac and assignes the value to the variable D
An if statement is used to test if D is less than 0, if this is true the message no real solutions is printed
