Comment

Instead of sizeof() for finding the length of strings or character 
arrays, just use strlen(string_name) with the header file
#include <cstring>   
it's easier.

	// find the ligth of the array of character 
	char arr[10] = "Romany";
	cout << "the size of the character array = " << sizeof(arr) / sizeof(char) << endl;


	// find the actual length (number of characters in the array)
	while (arr[i] != '\0') i++;
	cout << "number of characters in the array = " << i << endl;
