Conversione da intero a stringa

[keratox]

Tratto da un libro

Converting an integer value to a string of characters takes even more effort. The algorithm for the conversion is the following:

1- Initialize a string to the empty string.

2- If the integer value is zero, then output a 0, and the algorithm is complete.

3- Divide the current integer value by ten, computing the remainder and quotient.

4-Convert the remainder (always in the range 0..9) to a character, and concatenate the character to the end of the string.

5- If the quotient is not zero, make it the new value and repeat steps 3-5.

6- Output the characters in the reverse order they were placed into the string.

Ho provato a fare

	int i=0,a,d=0;
	char str2[3];

	for(a=2;a>=0 && i%10!=0;a--){
		d=i%10;
		i/=10;
		str2[a]=(char)d;
	}
	printf("Stringa -> %s\n\n",str2);

Ma mi ritornano caratteri strani, dove ho sbagliato?
