Char substring copy function

[techjohnny]

I have a working CHAR function, but would like some feedback on possibly making it better.

I haven't created the prototype yet, but expect it to take on 5 parameters.

        const int resultBuff = 20;
        const int Buff = 20;
	char ch[Buff] = "Joe Johnson";
	char k[resultBuff] = ""; ;
	int start = 5;
	int length = 6;
	int count = 0;

	for (int i = start; i < start+length; i++)
	{
		k[i - start] = ch[i];
		count++;
	
	}
	k[count] = 0;
	cout << k << endl;

This is a code snippet to extract a substring from a larger string. To make the code look better you can write like this :

    const int RESULT_STRING_SIZE = 20;
    const int ORIGINAL_STRING_SIZE = 20;

	char str_original[ORIGINAL_STRING_SIZE] = "Joe Johnson";
	char str_result[RESULT_STRING_SIZE];

	int str_start = 5;
	int str_length = 6;

	int string_len = strlen(str_original);

	int i, count = 0;
	for (i = str_start; i < str_start + str_length && i < string_len; i++, count++)
	{
		str_result[count] = str_original[i]; 
	}

	str_result[count] = 0;

	cout << str_result << endl;
