Question

Guys I almost finished my yesterday's assignment, just need to tweak the code a little. Can anyone help?

Answer 1

Okay unfortunately, nobody's code yesterday worked.

Answer 2

#include<iostream>

using namespace std;

int main()
{
cout << "Enter a month (1-12): ";
double month;
cin >> month;
while (month!=1 || month!=2 || month!=3 || month!=4 ||
month!=5 || month!=6 || month!=7 || month!=8 ||
month!=9 || month!=10 || month!=11 || month!=12)
{
if (month==1 || month==2 || month==3 || month==4 ||
month==5 || month==6 || month==7 || month==8 ||
month==9 || month==10 || month==11 || month==12)
break;
else
{
cout << "An invalid month has been entered, please try again: ";
cin >> month;
}

}

cout<<"A valid month has been entered."<<endl;

system("pause");
return 0;
}

Answer 3

That's what I have and it works perfectly fine. All I need is...

Answer 4

lol is this the programming section?

why store month as a double instead of an int?

What error is the compiler returning?

Answer 5

this code accepts 1.0 or 1.00000 which is true, but i only want it to accept 1

Answer 6

that's it, store month as an int, not a double

Answer 7

well here's the thing, if I store it as an integer, it is accepting 1.1 etc..

Answer 8

Because that's how an integer works, it drops whatever is after the integer part

Answer 9

I was thinking of using characters..

Answer 10

but I can't figure out how to set the conditions, i keep getting errors and stuff

Answer 11

use the ascii value would they work ? i'm not sure i've never attempted it

Answer 12

hmm I don't know lol let me try... but the code above is the closest i ever got to completing this crap, even yesterday's complicated codes that were posted here didn't work..

Answer 13

this is why C++ isn't for beginners.

if this was in python you won't get weird problems like this.

Answer 14

lol I am actually liking C++, like I've only had a class for 2 weeks and we've done a lot..

Answer 15

construct an array of integers from 1 to 12, and compare 'month' to the elements in that array.

Answer 16

i can't.. i can only use if/else/while and we didn't learn arrays yet..

Answer 17

oh okay... let me reflect on the code.. >.< what is it supposed to do?

Answer 18

okay here's the thing it is only supposed to accept these things:
1
2
3
4
5
6
7
8
9
10
11
12
That's all, no 1.0 or 1.1 or 15 or 0

Answer 19

If it gets one of those values it is supposed to ask you to try again

Answer 20

And it works fine.. but it keeps accepting 1.0, which is always going to be accepted if I use any type of number data type..

Answer 21

actually all i need is to find, the following codes so to speak:
how can I write:
Character is not
and
Character is
char month;
while (month!='1') didn't work

Answer 22

ah well gtg I will crack this eventually... and im really close haha

Answer 23

#include <iostream>
#include <stdlib.h>
#include <string>

using namespace std;

int main()
{
cout << "Enter a month (1-12)";
string month;
cin >> month;
while (! (month == "1" || month == "2" || month == "3" ||
month == "4" || month == "5" || month == "6" ||
month == "7" || month == "8" || month == "9" ||
month == "10" || month == "11" || month == "12")){
cout << "\n" << month <<" is not a valid month, please try again" << endl;
cin >> month;}
cout << month << " is a valid month!" << endl;
system("PAUSE");
return 0;
}

There; by storing month as a string literal, we can effectively test month for a valid input value.
