C-Style Strings: Working with Character Arrays
C-style strings are arrays of characters ending with a null character '\0'. They are different from C++ std::string but still widely used. You can use functions from <cstring> like strlen(), strcpy(), and strcmp() to manipulate them.

Breakdown
1
#include <iostream>
Header for input/output operations
2
#include <cstring>
Header for C-string manipulation functions
3
char greeting[] = "Hello";
Character array initialized with a string literal
4
char name[20];
Declares space for up to 19 characters plus null terminator
5
std::cin.getline(name, 20);
Reads a full line including spaces into the name array
6
strlen(name)
Returns the length of the string without the null terminator
