The difference is:
Pre incrementing increment the variable and then use it
Post incrementing uses the variable and then increment it
Example:
c = 2;
cout << ++c;
cout << c;
Output:
3

c = 2;
cout << c++;
cout << c;
Output:
2
3
In case of cout << ++c+c++; I would advise you to read this: https://www.sololearn.com/Discuss/3095184/?ref=app
