Hey there! I'll be really thankful if you help me with this task...I'm translating it from my language so there might be mistakes but I hope you're going to understand what I'm talking about:

Create a program with function main() and menu with functions for:
A) Inserting several numbers from the keyboard into one-dimensional array (the numbers should be less than 20);
/> Overwriting of the 1st array into second array in which the elements are put in reverse order.
C) Overwriting of the second array into third array in which the elements are put in descending order.
D)Displaying information about the array. (I guess this is A,B and C)



I'm really not good in C++ so I don't need anything complicated. This is what I have done so far:

#include <iostream>
using namespace std;
const int MAX_SIZE = 20;
int inserting (int elements []);
int reverseorder (int elements []);
int descendingorder (int elements[]);
int display (int elements[]);

int main(){
	int choice;
	cout << "1. Insert several numbers" << endl;
	cout << "2. The numbers in reverse order" << endl;
	cout << "3.The numbers in descending order"<< endl;
	cout << "4. Display array with information"<<endl;
	cout << "\n Type your choice here:" ;
	
	cin >> choice;
	if (choice < 5 && izbor > 1) continue;	// here I get a message that continue statement is not withing a loop
	switch (choice)
	{
		
	case 1: int inserting (int elements []);
	case 2: int reverseorder (int elements []);
	case 3: int descendingorder (int elements[]);
	case 4:	int display (int elements[]);

	} // I am not really sure if the whole switch statement is correct...I get a message "Error:expected primary-expression before "int"".

After I do this I have to start writing the functions but I find difficulty to do it....Any help will be appreciated...


Thanks in advance,

Hello!

When I tried to compile your code using ideone.com I got the following compiler errors

prog.cpp: In function ‘int main()’:
prog.cpp:19:20: error: ‘izbor’ was not declared in this scope
if (choice < 5 && izbor > 1) continue;
^
prog.cpp:19:31: error: continue statement not within a loop
if (choice < 5 && izbor > 1) continue;
^
prog.cpp:28:2: error: expected ‘}’ at end of input
}
^

Perhaps it is from the translation, but if izbor is a variable, it needs to be declared within the scope before you use it,

adding for example, int izbor = 0; should help.

I believe we can get rid of the continue; as well and just set it up like this

if (choice < 5 && izbor > 1)
{
switch ( stuff )
{

case 1:
case 2:
}
}

Also, don't forget to add breaks to your case statements! Check out this website for some tutorials on switch/case, and other things. They really helped me out when I was getting started

http://www.learncpp....tch-statements/ For switch/case stuff.

Also, don't forget to add another } to the end of your main, it looks like you're missing one

The error you're receiving is because you're re-declaring your functions in the switch-case statement. Remove "int" from the beginning of the functions so you don't redeclare them. Also, you need to pass in an array, not an array declaration.

#include <iostream>
using namespace std;
const int MAX_SIZE = 20;
int inserting (int elements []);
int reverseorder (int elements []);
int descendingorder (int elements[]);
int display (int elements[]);

int main(){
	int choice;
	int array_1[MAX_SIZE];                               // Declare first array
	int array_2[MAX_SIZE];                               // Declare second array
	int array_3[MAX_SIZE];                               // Declare third array
	cout << "1. Insert several numbers" << endl;
	cout << "2. The numbers in reverse order" << endl;
	cout << "3.The numbers in descending order"<< endl;
	cout << "4. Display array with information"<<endl;
	cout << "\n Type your choice here:" ;
	
	cin >> choice;
	if (choice < 5 && izbor > 1) continue;	// here I get a message that continue statement is not withing a loop
	switch (choice)
	{
		
	case 1: 
	    inserting (array_1);
	    break;
	case 2: 
	    reverseorder (array_2);
	    break;
	case 3: 
	    descendingorder (array_3);
	    break;
	case 4:	
	    display (array_1, array_2, array_3);
	    break;
	default:
	    break;

	} // I am not really sure if the whole switch statement is correct...I get a message "Error:expected primary-exp<b></b>ression before "int"".

Hey,I tried the code which IngeniousHax wrote but I get this message when I try to run the program:

[Salem_c]

> int inserting (int elements []);
Well, having written this, you've made a promise to at some point write this.

int inserting (int elements []) {
  // do something which resembles inserting into the array
  // what you insert, how many you insert, and where you
  // get them from is up to you.
}

> 21 if (choice < 5 && izbor > 1) continue; // here I get a message that continue statement is not withing a loop
For now, just delete this line.
Error checking and retry can come later.
