Hur f*n anropar man funktionen korrekt? I filen vector_strings.cpp har jag skrivit "Adder();" och där behövs tydligen någon parameter som ska in i "Adder(std::vector<std::string>& names)". Finns här någon kunnig själ som kan hjälpa till lite?
Kod:
******************
main.cpp
******************
#include <iostream>
#include "vector_strings.hpp"
int main(void) {
CMDReader();
return 0;
}
******************
vector_strings.hpp
******************
#ifndef VECTOR_STRINGS
#define VECTOR_STRINGS
#include <vector>
#include <string>
void CMDReader();
void Adder(std::vector<std::string>& names);
void Remover(std::vector<std::string>& names);
void Printer(std::vector<std::string>& names);
#endif

/*
Implement a program that stores and removes given strings from a
vector, as commanded by the user. You should implement a simple
command line interface that implements the following.
In the beginning, program should print `Commands: ADD, PRINT, REMOVE, QUIT`,
followed by a newline. Then print `Enter a command:` followed by a newline.
Then the program should read the command from the user and do the following:
* **ADD**: Add a given string to the vector. The program should first
prompt: `Enter a name:` (without trailing space) followed by a newline. Then
it reads the name from the user and adds it to a the
vector. Finally, it prints: `Number of names in the vector:`, a
newline, the size of the vector, and finally newline. The ADD
functionality is implemented in the function `Adder`.
* **REMOVE**: Removes the last string from the vector. This
operation is implemented in the function `Remover`. The function
should print the removed string in the following way: `Removing
the last element:`, followed by a newline, then the string and a
newline.
* **PRINT**: Outputs all stored strings, each on a separate line
(e.g., followed by newline character). This operation is
implemented in function `Printer`.
* **QUIT**: Exit the program.
In addition to the above three functions, you need to implement
the function `CMDReader` that parses the commands and calls the
appropriate functions. The detailed function interfaces can be found
in the file *vector_strings.hpp*.
Here is an example of an session:
Commands: ADD, PRINT, REMOVE, QUIT
Enter a command:
ADD
Enter a name:
Kalle
Number of names in the vector:
1
Enter a command:
ADD
Enter a name:
Nisse
Number of names in the vector:
2
Enter a command:
PRINT
Kalle
Nisse
Enter a command:
REMOVE
Removing the last element:
Nisse
Enter a command:
QUIT
