C++ Coding Question on parsing a string

If i have a string like "ADD X1, X2, X3"

and i wanted to split the string as follows:
ADD
X1
X2
X3

what is a style of code i can use to parse the string into obtaining each of the following without taking things such as commas and spaces.

Answer 1

#include<iostream>
using namespace std;
int main()
{
// enter a string from the user
cout<<"Enter a string:\n";
string str;
getline(cin,str);
// initialize a temporary word as empty string
string temp_word ="";
// iterate through the string
for(auto i : str)
{
// if space or comma occur then print the temporary word and initialize it back to empty string
if(i == ' ' || i == ',') // here you can write more special characters to consider
{
cout << temp_word << "\n";
temp_word = "";
}
// if space or comma doesn't occur then simply add another character to the temporary word
else
{
temp_word = temp_word + i;
}

}
// print the last word
cout<<temp_word<<"\n";
return 0;
}
