function not printing result in menu program

[ForrestDumps]

Program is meant to allow the user to make several menu choices and print a total once they're done. Discount price is applied for items in multiple of two thus the if/else statement. Currently the menu selections [appear to] work, but selecting 5 simply terminates the program with no output. Any hints on where I'm going wrong here? Thanks in advance.

#include <iostream>

using namespace std;

// constants for pricing
const double SINGLE = 3.59,
               PAIR = 5.99;
    
// prototypes
void showMenu();
void orderTotal(float& total);


int main() {
// constants for pricing
const double SINGLE = 3.59,
             PAIR = 5.99;

    qty=0,

    showMenu();
    cout << "Please make a selection: \n";

in line 65 you are calling the fucntion wrong

orderTotal(float qty1, float qty2, float qty3, float qty4);

remove the void, that is not how you call functions

[ForrestDumps]

Good catch, unfortunately now I'm getting the error "expected primary-expression before 'float'" for line 65. Any ideas there? Tried fiddling around with it but so far no luck.

See http://www.cplusplus.com/doc/tutorial/functions/ for examples of how to call functions.

Something just isn't clicking with me. I've read through that link a couple times, watched a couple videos and still nothing.

Another basic tutorial on function parameters and arguments:
https://www.learncpp.com/cpp-tutorial/introduction-to-function-parameters-and-arguments/

[seeplus]

The function prototype on L13 doesn't match the function definition on L89.

Also as mentioned above, L65 should be:

orderTotal(qty1, qty2, qty3, qty4);
