2. Write a program to input a number x from the keyboard. If the number is larger than 0, find its square root. Otherwise, calculate x* x. Write the program by using selection statement. A sample of the output showed as below. Please enter a positive or negative number: -4 You have entered -4 which is smaller than 0 Therefore -4 x -4 = -8 Hint: Use include to include sqrt function. Example: root=sqrt(x);
