I want to press a key to continue

[CrazyMike97]

Hello

My problem is , i want to make a simple calculator , in the console i want afterall the user to choose what type of operation he want pressing a key like i mentioned in the title the keys would be F1,F2,F3 , i'm not finding in the internet the code to the detection of a press key like what i want.

Thank you

  #include <iostream>

using namespace std;

int F1 (int x, int y)
{
	cout << "Enter a number: " << endl;
		cin >> x;
	cout << "Enter a number: " << endl;
		cin >> y;

	int answer = x + y;


	return answer;
}

int F2 (int z, int c)
{
	cout << "Enter a number: " << endl;
	cin >> z;
	cout << "Enter a number: " << endl;
	cin >> c;

	int minusanswer = z - c;

	return minusanswer;

}


int F3 (int v, int b)
{
	cout << "Enter a number: " << endl;
	cin >> v;
	cout << "Enter a number: " << endl;
	cin >> b;

	int multipanswer = v * b;

	return multipanswer;

}

int main()
{
	cout << "What Type of calculation do you wanna make? " << endl;
	cout << "F1--> addition   " << "   F2-->subtraction   " << "   F3-->multiplication" << endl;
	

	if (F1)
		F1(1,1);

	else if (F2)

		F2(2, 2);


	else if (F3)

		F3(2, 2);
	





		return 0;

you can use GetAsyncKeyState function
