Lists (Arrays)

Lists are a collection of things. The term list is most commonly used for a collection that is indexed continuously which can store values of many data-types. The term array is most commonly used for a collection that is indexed continuously but only stores values of a single data-type.

Examples here feature a list (array) of strings in various languages.

Python

strings = ["Hello", "World"]
print(strings[0]) #--> Hello
print(strings[1]) #--> World
print(len(strings)) #--> 2

Lua

-- Global var
strings = {"Hello", "World"}
print(strings[1]) --> Hello
print(strings[2]) --> World
print(#strings) --> 2

#include <stdio.h>
int main() {
    // Auto appends null terminator
    char str[] = "Hello World";
    // sizeof is builtin
    printf("%zu\n", sizeof(str)); // Gives 6
    return 0;
}

C++

#include <iostream>
#include <string>
int main() {
    std::string str = "Hello";
    // Gives 6 including null terminator.
    std::cout << str.size() << std::endl;
    return 0;
}
