Question

Create a CPP file for a C++ Program.

Write exactly these functions, power(x,y) function and a print(text, number) function and the main() function. The power(x,y) function returns an integer result that is calculated by raising a number x (integer) to a power y (integer).

The second argument y (exponent) of the function can not exceed 100.

If the second argument exceeds 100, the function should return -1.

Your power(x,y) function must be able to take either 1 or 2 integer arguments using the concept of default argument. Look at the main() code to infer what the default value should be.

You can use pow(x) function in the "cmath" library in the body of your power(x,y) function

The print(text, number) function is the only one that does output to the console using "cout". Other functions should not use "cout".  

Write the 2 function prototypes above main() and write the full function definitions after main().

Use this given main() code without change:

// Function Prototypes go here ………...

//

int main()

{

  int x = 3;

  x = power(x, 3);

  print("Value of x after step 1 is ", x);

  x = power(x, 2);

  print("Value of x after step 2 is ", x);

  x = power(x);

  print("Value of x after step 3 is ", x);

  x = power(x, 101);

  print("Value of x after step 4 is ", x);

  x = power(3, -5);

  print("Value of x after step 5 is ", x);

  x = 10;

  x = power(x);

  print("Value of x after step 6 is ", x);

  return 0;

}

// 2 Function definitions go here ………...

Program Output:

Value of x after step 1 is 27

Value of x after step 2 is 729

Value of x after step 3 is 729

Value of x after step 4 is -1

Value of x after step 5 is 0

Value of x after step 6 is 10
