void func2(int &, int &, int &);
void func3(int, int, int);
int main()
{
int x = 0, y = 0, z = 0;
cout << x << " " << y << " " << z << endl;
func1(x, y);
cout << x << " " << y << " " << z << endl;
func2(x, y, z);
cout << x << " " << y << " " << z << endl;
func3(x, y, z);
cout << x << " " << y <<" " << z << endl;
return 0;
}
void func1(int &a, int &b)
{
cout << "Enter two numbers: ";
cin >> a >> b;
}
void func2(int &a, int &b, int &c)
{
b++;
c−−;
a = b + c;
}
void func3(int a, int b, int c)

The first number is the dividend, and the second number is the divisor. If the divisor is equal to zero, display an error message "The divisior can NOT be zerof"; otherwise, display the quotient as a float-point value with one decimal place. For example, if the user enters 10 and 3, display the message "10 divided by 3 is 3.3". Attach File Browse Local Files Browse Content Collectionarrow_forward
