Chapter # 05: FUNCTIONS

Q.1: What do you know about functions?

Ans:
INTRODUCTION TO FUNCTIONS
A function is a block of code that performs a particular task. It is also called a method or a sub-routine or a procedure, etc. There are some situations when we need to write a particular block of code more than once in our program. This may lead to bugs and irritation for the programmer. C++ language provides an approach in which you need to declare and define a group of statements once and that can be called and used whenever required. This saves both time and space. Every C++ program has at least one function, which is main(), and all the programs can define additional functions.

Control structures control the flow of execution in a program or function. Control structures are used to repeat any block of code, transfer control to a specific block of code, and make a choice by selection. There are three basic control structures in C++ programming:

1. Selection / Decision Making Control Structure
2. Loops / Iteration Control Structure
3. Jumps

PROBLEM SOLVING AND ALGORITHM DESIGNING

Q.1: What is problem solving?
Ans.
PROBLEM SOLVING:
Problem solving is a procedure to figure out the solution of complex problems. Problem solving is the main process in computer programming, where programmers first understand the problem, plan the solution, and then understand how to translate the algorithm into something a computer can do, and finally how to write the specific syntax or code required by a computer to get the job done.
