String Concatenation and Methods
The string class provides powerful text manipulation. Use + to concatenate strings, length() to get character count, and indexing with [] to access individual characters. The range-based for loop iterates through each character.

Breakdown
1
std::string fullName = firstName + " " + lastName;
Concatenates two strings with a space in between
2
fullName.length()
Returns the number of characters in the string
3
fullName[0]
Accesses the first character using zero-based indexing
4
for (char& c : fullName)
Range-based for loop that gives direct reference to each character
