Problem Solving and Programming

A program which provides a set of tools to make it easier for programmers to write, develop and debug code.

This allows you to monitor the effect of each individual line of code by executing a single line at a time.

Sometimes used to pinpoint errors, this is a useful feature to observe how the contents of a variable change in real-time through the execution of a program.

IDEs allow users to set a point in the program at which the program will stop. This can either be based on a condition or set to occur at a specific line. This can help to pinpoint where an error is occurring.

The editor aims to make the coding process easier by providing features such as autocompletion of words, indentation, syntax highlighting and automatic bracket completion.

Some IDEs also provide run-time detection of errors with a guide as to where in the code they are likely to have occurred through line numbers and highlighting.

The values passed into a function

Procedures and functions are both named blocks of code that perform a specific task.

Procedures do not have to return a value; functions must always return a value. Procedures can return multiple values whereas a function must return one, single value

When a parameter is passed by value, the value created for the subroutine being called is a copy of the original. Once it is passed, the parameter is held in a separate memory location, so is only available to that subroutine meaning the copy is now a local variable of that subroutine

When a parameter is passed by reference, a pointer that contains the memory address of the original variable is created This means that any changes to that value from within the called subroutine will also affect the original variable

Identifier of a memory location used to store data

The range of statements/ procedures/ functions/ methods that a variable is valid for

A type of variable, usually defined at the start of a program, where the variable can be used everywhere in the program

A variable that is only valid within the procedure/ function/ sub routine in which they are declared

The local variable will take precedence over the values in the global variable

Converts the users high level code into executable machine code

It is software that supports the execution and running of programs, so developers can run their code during development
