Is it allowed to use arrays?

[SamuelAdams]

This should help

#include <conio.h>
#include <stdio.h>
#include <iostream>
using namespace std;

int main()
{
	int num, hund, tens, ones, temp;
// 	system("cls");
	printf("Enter a number from -999-999: ");
	scanf("%d", &num);

	// ex. : 123
	hund = num / 100;	// hund = 1
	temp = num % 100;	// temp = 23
	tens = temp / 10;	// tens = 2
	ones = temp % 10;	// ones = 3
	if(num >= -999 && num < 999) // Check to see if num is valid
	{
		
	//hundreds

This is what I came up with. I wasn't sure if arrays are allowed, so I used them anyway. It's much much shorter and quite impossible to make a mistake if you're careful.
Didn't do too much error checking...

#include<stdio.h>
#include<conio.h>

int main()
{
	int num;
	system("cls");
	printf("Enter a number from -999 to 999: ");
	scanf("%d", &num);

	int ones = num / 1 % 10;
	int tens = num / 10 % 10;
	int hund = num / 100 % 10;

	const char *one[] = {" ", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten"};
	const char *ten[] = {" ", "ten", "twenty", "thirty", "forty", "fifty", "sixty", "seventy", "eighty", "ninety", "hundred"};
	const char *ten2[] = {"ten", "eleven", "twelve", "thirteen", "fourteen", "fifteen", "sixteen", "seventeen", "eighteen", "nineteen"};


	if (num < 0)
	{
		printf("Negative ");
		//makes all the digits positive since the number entered is negative
		hund = hund - hund * 2;
		tens = tens - tens * 2;
		ones = ones - ones * 2;
	}

	if (num >= -999 && num <= 999)
	{	
		if (tens == 1)
		{
			printf("%s hundred %s", one[hund], ten2[ones]);
		}
		else
		{
			printf("%s hundred %s %s", one[hund], ten[tens], one[ones]);
		}
	}
	else
	{
		printf("Your number is out of range!");
	}

	getch();
	return 0;
}

Thanks samueladams,

the code was definitely a big help

though the only values that works are from positive 100 to 999 :(

[testerthe1]

thanks too sasauke,

but we're not allowed to use arrays :\

[xbv]

had something similar to sasauke before I noticed there were replies below xD

If you can't use arrays use a big string, all words seperated by a space, and find the correct item depending on the number

char *ones_str="one two three four etc";

and use the same sort of code to print out the goods
