"Procedural" Programming

• creation of proceedures (functions)
  
  

  combine returning sequences of statements into one single place. A procedure call is used to invoke the procedure.

  After the sequence is processed, flow of control proceeds right after the position where the call was made
  
  
  

• advantages:
  • some code reusibility (within a program)
  • concept of parameter passing to proceedures/functions.
  • flow of data can be illustrated as a hierarchical graph, a tree
    
    
    
    
• disadvantages:
  • how can other programs share the same proceedures?
  • high dependence of code on proceedures.
