(P1) Fundamentals of Programming

Data types are defined by the values it can take or the operations that can be performed on it.

A whole number, positive or negative. Including zero.

A positive or negative number which can have a fractional part.

Value which is either true or false.

A single number, letter or symbol.

A collection of characters.

Way of storing a point in time, many different formats are used.

Way of storing memory addresses.

Collection of fields, each of which could have a different data type. Rows from a table.

An indexed set of related elements each of which has the same data type.

Creating a variable for the first time, giving it a name and sometimes a data type. This allocates a portion of the computer’s memory to the variable.

Creating a constant for the first time, giving it a name and a data type. The value of the constant does not change while the program is running.

Giving a constant or variable a value.

Repeating an instruction, this could be definite or indefinite.

Comparing values and choosing an action based on those values.

A named block of code containing a set of instructions designed to perform a frequently used operation.

For loop While loop

Iteration in which the number of repetitions required is known before the loop starts.

Iteration in which the number of repetitions required is not known before the loops starts.

For loop.

While loop.

Nested: One structure is placed within another. Identified by indentations.

Use indentations. Choose sensible indentifier names.

When one value is divided by another, both a quotient and the remainder are returned.
