  FUNCTIONS IN C PROGRAMMING MAWEJJEALLAN
• 2.
  DEFINE FUNCTION A functionis a block of code designed to perform a specific task. • Purpose 1. Code Reusability 2. Improved Readability 3. Simplified Debugging
• 3.
  FUNCTION STRUCTURE COMPONENTS •Function Declaration •FunctionDefinition •Function Call
• 4.
  1. Function Declaration Astatement that tells the compiler about the function name, return type, and parameters. int add(int a, int b);
• 5.
  2. Function Definition •Theactual implementation of the function. int add(int a, int b) { return a + b; }
• 6.
  3.Function Call Invoking thefunction to execute its code. int result = add(5, 10);
• 7.
  TYPES OF FUNCTIONS •STANDARDLIBRARY FUNCTION: Provided by libraries (printf, scanf.) •USER-DEFINED FUNCTION: Created by the programmer. •FUNCTIONS WITH RETURN VALUES: Functions that do not return a value.
• 8.
  IMPORTANCE OF FUNCTIONS •ImprovedReadability •Simplified Debugging •Enhanced Maintainability •Code Reusability
• 9.
  IN CONCLUSION Functions areessential for organizing code, enhancing reusability, and making debugging easier.
