Iterating Over a C-Style String

Write a program that declares a null-terminated C-style string and prints each character on a seperate line using a loop, stopping at the null character ('\0').

Answer

#include <iostream>

int main() {
    // Declare a null-terminated C-style string
    char cString[] = "Hello, World!";

    // Iterate over the string using a for loop
    for (int i = 0; cString[i] != '\0'; ++i) {
        std::cout << cString[i] << "\n";
    }
    std::cout << std::endl;
}

The program starts by declaring a C-style string, which will automatically end with a null character. A for loop is used to iterate through each character of the string. The loop continues until the active character is the null character ('\0').
