C++ Programming: For Loop and One Dimensional Arrays

Study Notes

Purpose of the 'for' Loop in C++

A 'for' loop is used to execute a block of code a specific number of times.
It consists of three parts: initialization, condition, and update.
Commonly used for iterating over arrays or performing repetitive tasks efficiently.

Nested Loop in C++

A nested loop refers to a loop inside another loop.
The inner loop executes completely for each iteration of the outer loop.
Useful for tasks requiring multidimensional data handling, such as matrix operations.

Purpose of an Array in C++

An array is a collection of elements, all of the same data type, stored in contiguous memory locations.
It allows for efficient data organization and easy access to elements via indexing.
Commonly used to handle lists, tables, or any related data in a single structure.

'dataType arrayName[arraySize];' Representation in C++

This declaration defines an array with a specific data type, name, and size.
'dataType' indicates the type of elements (e.g., int, float).
'arrayName' is the identifier used to reference the array.
'arraySize' specifies how many elements the array can hold, which must be a constant value.

Update Part of a 'for' Loop in C++

The update part is executed after each iteration of the loop's block.
It modifies the loop control variable, affecting the loop's condition for the next iteration.
Essential for progressing towards the termination of the loop and preventing infinite loops.
