13_DashInsertII.cpp

// For this challenge you will be manipulating a string using dashes (-).
// have the function DashInsertII(str) insert dashes ('-') between each two odd numbers and insert asterisks ('*') between each two even numbers in str. For example: if str is 4546793 the output should be 454*67-9-3. Don't count zero as an odd or even number.

#include <string>

	// Converting the integer number into a string type
	stringstream convert;
	convert << num;
	string temp = convert.str();
	string temp2;

	for (int x = 0; x < temp.length()-1; x++)
	{
		// Ignoring the zero
		if (temp[x] == '0' || temp[x+1] == '0')
