  • Important 2nd year computer chapter 13 short questions for Intermediate part-II students.
  • What is modular programming?: Ans: A programming technique in which a program consists of many independent parts is called modular programming. These parts are called modules. These parts are also called function. Each module can perform different tasks. The development speed of a program increases as different programmers can write different modules of a program. Different modules are combined to make a complete program.
  • Important 2nd year computer chapter 13 important long questions for Intermediate part-II students.
  • What is a function?
  • Why functions are used?
  • What are built-in functions? 
  • What are user-defined functions?
  • What are function prototypes?
  • What is function definition?
  • What is a function header?
  • What is the function calling?
  • What is a return statement?
  • Important 2nd year computer chapter 13 long questions for Intermediate part-II students.
  • What are the parameters?: Ans: Parameters are also called arguments. These are the values that are provided toa function when it is called. when function is called parameters are written after function name in parenthesis. These parameters can be variables or constants. More than one parameter is separated by comma.
  • What is a local variable?
  • What is a global variable?
  • What is meant by the lifetime of a variable? 
  • What is meant by the scope of a variable?

  • What is the scope of the global variable?: Ans: Global variables can be accessed in all modules of program. They are accessible in main() function as well as all other user defined functions.
  • What is the lifetime of a global variable?
