Question

How can i get my program to just print out numbers 1 to 5? For example if I put in a 12 it will take the 1 as an output. Code in comments

Answer 1

int main()
{
char number;

cout << "Enter a number from 1 to 5: ";
cin >> number;
switch (number)
{
case '1': cout << "The Roman numeral equivalent is: I" << endl;
break;
case '2': cout << "The Roman numeral equivalent is: II" << endl;
break;
case '3': cout << "The Roman numeral equivalent is: III" << endl;
break;
case '4': cout << "The Roman numeral equivalent is: IV" << endl;
break;
case '5': cout << "The Roman numeral equivalent is: V" << endl;
break;
default: cout << "The number must be in the range of 1 through 5 inclusive." << endl;
}

Answer 2

The problem is you are taking in just one character.

Answer 3

So would I do int 1-5?

Answer 4

int number?

Answer 5

Int number, then change the cases too.

Answer 6

Also, if you want to pase code there are better ways. Pi a 1``` above and below so it formats it for being copied:
```
#include <iostream>
using namespace std;

int main() {
int number;
cout << "Enter a number from 1 to 5: ";
cin >> number;
switch (number) {
case 1:
cout << "The Roman numeral equivalent is: I" << endl;
break;
case 2:
cout << "The Roman numeral equivalent is: II" << endl;
break;
case 3:
cout << "The Roman numeral equivalent is: III" << endl;
break;
case 4:
cout << "The Roman numeral equivalent is: IV" << endl;
break;
case 5:
cout << "The Roman numeral equivalent is: V" << endl;
break;
default:
cout << "The number must be in the range of 1 through 5 inclusive." << endl;

}
}
```

Answer 7

For larger blocks of code there are also services like http://pastebin.com/ and http://dpaste.com/ that can help keep messages from getting too long. They can also do code highlighting, which makes it more readable.

Answer 8

Okay I see. How is case '1' different from case 1?

Answer 9

'1' s a character.
1 is a number.

Answer 10

Or more specifically, 1 is an integer, 1.0 is a float, etc.

Answer 11

Alright. Thanks a lot!!

Answer 12

And in programming speak: Because C/C++ is strongly types you need to have a type agreement in the switch. If you try it with different ones, you will get some sort of type mismatch error.

Have fun!

Answer 13

strongly typed.... not s. hehe.

Answer 14

u can still use a char and it would be the best choice because it takes less memory though this isnt necessary anymore. todays pcs have enough ram. just use "case 1:" instead of "case '1':".
When u use '1' it equals 49 because the character '1' is at the 49th position in the ascii table.
