Array [Wayy less complicated than other posts]

[Robert_Sitter]

ok, well, looking at the other posts in this forum I'm the least experienced here, hope you all don't mind me asking these questions.

Now, I've been learning about arrays the past few days and have no problems getting text to display from one, but, how do you take text from a 'char' array by inputting a number?
Here is what I'm trying to do:

#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
	const int months[]={'j','f','m','a','m','j','j','a','s','o','n','d'};
	const int days[]={31, 29, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};
	int kbi=0, int kbin=0, int count=0;
	cout << "Enter date in # format (ie, 1,2,3...12): ";
	cin >> kbi;
	kbin=(kbi-1);

	for(;kbin=kbin	
{	
	cout << "The month " << months[kbin] << " has " 
		 << days[kbin] << " days in it.";

system("pause");
return 0;
}
//kill
system("pause");
return 0;
}

For some reason when I enter 1 for 'j' January I get "The month 106 has 31 days in it", umm, that's a far cry from the 31 it's supposed to have.
I heard of a static_cast a few days back, is that needed here?

Thanks for your help (and previous help)

when you assign a 'char' to an integer.. you are assigning the ascii value of that char into the integer variable..

you can do that if you want.. but if you want to display the character instead of the ascii value.. you will have to cast your integer into a char:

char calandar_months[12]; 


for(int i=0; i<12; i++)

     calandar_months[i] = static_cast<char>(months[i]);

//calandar_months[]  now contains 'letters' instead of numeric ascii values

[ventolin]

You are outputting the integer equivalent of the ascii value of 'j' - type cast the month[kbin] variable to a char via:

cout << "The month " << (char)months[kbin] << " has "

This will print out the correct letter for you.

Hehe Thebrain beat me to it

Thanks again, I was suspecting it was going to be static_cast but wasn't sure how to use it.

Well, lol, maybe I'll be able to help you back someday,


have a good one,

(I'll hopefully have one of those 'complicated' questions next time! lol, that'll mean I've actually beat the super-novice stage!!!)

Thanks ventolin & thebrain!
But, as it turns out I was looking for a multi-dimensional array to get the result I wanted.
Thanks anyhow! Appreciate it!
Now I know what static_cast does anyhow

// 01.cpp : Defines the entry point for the console application.
// Stupid calendar that won't work

#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
	const char months[12][20]=
	{	"January",
		"February",
		"March",
		"April",
		"May",
		"June",
		"July",
		"August",
		"September",
		"October",
		"November",
		"December"
	};
	int kb=0, kbi=0;
	cout << "Enter date in # format (ie, 1,2,3...12): ";
	cin >> kb;
	kbi=(kb-1);

	while(kbi > 0)	
{	
	cout << "(" << months[kbi] << ") has " << " days in it.\n";
	system("pause");
	return 0;
}
//kill
system("pause");
return 0;
}

Hi,

If you are casting something, then you should rethink your code. A beginner should avoid doing any casting.

[Robert_Sitter]

There, I've figured it out, no casting or anything. Had put a double array where it didn't belong (days) and wasn't calling them properly.
Damn this can be COMPLICATED lol, wonder if anyone else thought that a week in...

Until next time people,

#include <iostream>
#include <iomanip>
using namespace std;

	{	"January","February","March","April","May","June","July",
		"August","September","October","November","December"
	};
    const double days[12]=
	{	31,29,31,30,31,30,31,31,30,31,30,31
	};


	int kb=0, kbi=0;
	cout << "Enter date in # format (ie, 1,2,3...12): ";
	cin >> kb;
	kbi=kb-1;

	while(kbi > 0)	
{	
	cout << months[kbi] << " has " << days[kbi] << " days in it.\n";
	system("pause");
	return 0;
}
//kill
system("pause");
return 0;
