Sequencing in programming

Back

Sequencing is the order in which instructions occur. Incorrect order can cause unexpected results or program failure.

Front

Example of sequencing error

Back

Using a variable before it is declared can cause a program to crash because the interpreter cannot find a variable that doesn’t exist.

Front

Selection in programming

Back

Selection is when a program chooses which path to take based on a condition, using constructs like 'if...else' and 'if...elif...else'.

Front

Example of selection

Back

A program performs different functions depending on user input.

Front

Repetition and iteration in programming

Back

Repetition and iteration occur when a program repeats a section of code.

Front

Count-controlled loops

Back

Count-controlled loops run a specified number of times, using 'for in range()' or 'while' loops.

Front

Condition-controlled loops

Back

Condition-controlled loops run as long as a condition is true, using 'while' loops.

Front

Iteration in programming

Back

Iteration shows that a program looks at every item in a data structure, using 'for each' loops.

Benefits of using subprograms

Back

- Code reuse: no need to retype code. - Easier debugging: isolate code areas with errors. - Improved readability and maintenance: view high-level logic without details.

Front

Separation of concerns in subprograms

Back

Subprograms allow for separation of concerns, enabling different jobs to be handled separately by different people at different times, enhancing teamwork.
