Monolithic Programming

A programming style where the entire program is written as a single, large function.

Modular Programming

A programming style where a program is divided into smaller, independent modules, each with a specific task.

Function

A block of code that performs a specific task.

Function Declaration (Prototype)

A statement that informs the compiler about a function's name, return type, and parameters.

Study Notes

Monolithic vs Modular Programming

  • Monolithic programming: A single function handles the entire program.
  • Modular programming: Divides the program into modules, each independently developed and tested. Modules are linked together.
  • Monolithic disadvantage: Difficult to debug and maintain large programs. Difficult to reuse code.
  • Modular advantage: Easier to code and debug modules. Code is reusable, and problems are isolated to specific modules.

Functions

  • A function is a group of statements that together perform a task.
  • Every C program has at least one function (e.g., main()).
  • Additional functions can be added.

Function Declaration/Prototype

  • Also known as a function prototype.
  • Tells the computer about:
    • Function name
    • Number and type of arguments
    • Return type
  • Syntax: return_type function_name(type1 arg1, type2 arg2); or return_type function_name(type1 type2);
  • If the called function is defined before the calling function, a declaration is not needed.

Function Definition

  • Consists of the code description and code of the function.
  • Two parts:
    • Function header: Describes the function's inputs/outputs.
return_type function_name(type1 arg1, type2 arg2)

- Function body: Contains the code to perform the task.

{
  local_variables;
  statements;
  return(expression);
}

User-Defined Functions

  • A function declared, called, and defined by the user.
  • Three parts:
    • Prototype/Declaration
    • Calling
    • Definition

Function Categories

  • Functions with no arguments and no return values.
  • Functions with no arguments and a return value.
  • Functions with arguments and no return values.
  • Functions with arguments and a return value.

Parameter Passing Techniques (Call by Value and Call by Reference)

  • Call by value: Original value is not changed. A copy of the argument is used by the function.
  • Call by reference: Original value is changed. The function receives the memory address of the argument. Any change in the function affects the original argument.

Recursion

  • A function that calls itself.
  • Useful for solving mathematical problems (e.g., factorial, Fibonacci sequence).
  • Advantages: Maintains function calling information, evaluations can be made via recursion.
  • Disadvantages: Slow due to stack overlapping, possibility of stack overflow.

Arrays

  • A data structure that holds multiple values (elements) of the same data type.

  • Allows for efficient access to data.

  • One-dimensional array: Single row of elements. Syntax: data_type array_name[size]

  • Two-dimensional array : Multiple rows and columns (matrix). Syntax: data_type array_name[rowsize][columnsize]

  • Initialization: Arrays can be explicitly initialized at declaration (int marks[5]={10,2,0,23,4}).
