Hey guys, im writing a program that takes a user's input and prints out a hexagon based on it.
i've nearly finished it but im a little stuck on two things the first is getting it to print horizontal lines as its supposed to do one row of horizontal line then one row of spaces.
the second is error checking i know in c# there is try parse to check if an input matches the data type but i don't know what the equivalent is in c++.
#include <iostream>
#include <string>
usingnamespace std;
//This class is to store all the functions needed to create the hexagons
class Hexagon
{
private:
//size stores the sizeInput value from the main class
//type stores the typeInput value from the main class
//fill stores the content to fill the hexagon
int size;
int type;
string fill;
public:
//int getSize() {return size;}
//int getType() {return type;}
// basic constructor and deconstructor to allow instances to be created
Hexagon(int sizeInput = 0, int typeInput = 0) : size(sizeInput), type(typeInput)
{
}
~Hexagon()
{
}
//function to create empty and filled hexagons
void BlankAndFill(int size, int type)
{
//checks which type of hexagon user wants and sets fill accordingly
if(type == 1)
{
fill = " ";
}
elseif(type == 2)
{
fill = "+";
}
//prints out what type of hexagon is being made
cout << "Type " << type << endl;
//stores row number for use as a counter
int rows = 0;
//prints out first half of the hexagon
for(; rows < size+1;rows++)
{
//for first row prints out top of hexagon
if(rows==0)
{
//this for loop prints out required spaces
for(int spaces = 1+size; spaces > rows;spaces--)
{
cout << " ";
}
//this for loop prints out top of hexagon

needed to ask different questions about same program and thought it'd be better to use my old topic instead of making a new one.
thought i'd also explain my attempt was to add a second counter in the rows loop then an if statement that prints out blank spaces if the row is even and lines if not.
but it instead just prints /----\ over and over again.
