Question

I am not understanding how to make it so when i input my selection in testSelection for it to point to the function test. How do i go about doing this? Shouldn’t it just go there?

 #include <iostream>
 using namespace std;

 int test (int testSelection);

 int main()
 {
int testSelection;

cout << "Welcome to the pizza place!" << endl;
cout << "Choose 1 for pizza or 2 for drinks: ";

cin >> testSelection;


return 0;

}

int test (int testSelection)
{
if (testSelection== 1)
{
    cout << "select your Pizza" << endl;

}
if (testSelection== 2)
{
    cout << "Please select your drink" << endl;

}
else
    cout << "test";

 return 0;
 }

You need to call the function…

cin >> testSelection;
test(testSelection);

Basically, you’ve written a function definition int test(int testSelection) {…code…} but, it’s just dormant code until you invoke it by calling it.
