Objective #12

 12. Solving simple programs through selecting structures, operators, repetitive structures and functions in pseudocode.

Selecting structures:

If:

• The if statement evaluates a condition and executes a block of code if the condition is true.

If / else:

• The if / else statement allows the program to execute different blocks of code based on whether a condition is true or false.

While:

• The while loop repeats a block of code as long as a specified condition is true.

Repetitive Structures:

• For:

• The for loop iterates a specific number of times, typically over a range of values.
• Do / while:
• The do / while loop executes a block of code at least once, and then repeatedly executes the block as long as a specified condition is true.

Functions:

• Definition:

• A function is a named block of code that performs a specific task or returns a value.
• Functions help in modularizing code, making it easier to understand, maintain, and reuse.

• Calling:

• To use a function, you call it by its name and provide any required arguments.

• Per Value:

• Function parameters passed by value create a copy of the original value, ensuring that changes made within the function do not affect the original variable.

• Per Reference:

  • Function parameters passed by reference allow the function to directly access and modify the original variable passed to it.
