Arrays in C++

Arrays

• An array is a constant variable, and its name should begin with 'k' according to Google Style.
• Arrays can hold different types of values.
• Arrays are initialized with a list of values enclosed in curly braces {}.
• Individual elements in an array can be accessed using the [] operator.
• If you try to access an element outside the array's bounds, it will result in overstepping bounds.
• The name of an array gives the memory address of the first element.
• Example of array declaration: int x = { 3, 7, 2 };

Arrays

• Size of an array is a constant variable, following Google Style, and should begin with k.
• Arrays can hold different types of values.
• Arrays can be initialized using a list enclosed in curly braces {}.
• Individual elements of an array can be accessed using the [] operator.
• Accessing an array element outside its bounds is called overstepping bounds.
• The name of an array is a pointer to the first element of the array.

Pointers

• To declare a pointer, the asterisk symbol * is used.
• Pointers can point to variables, arrays, or functions.
• There is a close relationship between pointers and arrays, with the name of an array being a pointer to its first element.
• The & symbol is the reference operator, used to get the memory address of a variable.
• The * symbol, when used as the dereference operator, retrieves the value stored at a memory address.

This quiz covers the basics of arrays in C++ including definition, size, initialization, and accessing individual elements.
