Instructions

Consider the provided C++ code in the main.cpp file:

The function func2 has three parameters of type int, int, and double, say a, b, and c, respectively. Write the definition of func2 so that its action is as follows:

• Prompt the user to input two integers and store the numbers in a and b, respectively.
• If both of the numbers are nonzero:
• If a >= b, the value assigned to c is a to the power b, that is, aᵇ.
• If a < b, the value assigned to c is b to the power a, that is, bᵃ.
• If a is nonzero and b is zero, the value assigned to c is the square root of the absolute value of a.
• If b is nonzero and a is zero, the value assigned to c is the square root of the absolute value of b.
• Otherwise, the value assigned to c is 0. The values of a, b, and c are passed back to the calling environment. After completing the definition of the func2 and writing its function prototype, run your program.

Provided code

#include <iostream>
#include <cmath>
#include <iomanip>
using namespace std;
void func1();
void func2(/*formal parameters*/);
int main()
{
int num1, num2;
double num3;
int choice;
cout << fixed << showpoint << setprecision(2);
do
{
func1();
cin >> choice;
cout << endl;
if (choice == 1)
{
func2(num1, num2, num3);
cout << num1 << ", " << num2 << ", " << num3 << endl;
}
}
while (choice != 99);
return 0;
}
void func1()
{
cout << "To run the program, enter 1." << endl;
cout << "To exit the pogram, enter 99." << endl;
cout << "Enter 1 or 99: ";
}
void func2(/*formal parameters*/)
{
//Write the body of func2.
}

Please find the code below:

#include <iostream>
#include <cmath>
#include <iomanip>
using namespace std;
void func1();
void func2(int a,int b,double &c);
int main()
{
   int num1, num2;
   double num3;
   int choice;
   cout << fixed << showpoint << setprecision(2);
   do
   {
       func1();
       cin >> choice;
       cout << endl;
       if (choice == 1)
       {
           cin>>num1>>num2;
           func2(num1, num2, num3);
           cout << num1 << ", " << num2 << ", " << num3 << endl;
       }
   }
   while (choice != 99);
   return 0;
}
void func1()
{
   cout << "To run the program, enter 1." << endl;
   cout << "To exit the pogram, enter 99." << endl;
   cout << "Enter 1 or 99: ";
}
void func2(int a,int b,double &c)
{
   if(b==0 && a!=0){
       c = sqrt(abs(a));
   }else if(a==0 && b!=0){
       c = sqrt(abs(b));
   }else if(a>=b){
       c = pow(a,b);
   }else if(a<b){
       c = pow(b,a);
   }else{
       c=0;
   }
