Decision making and branching

We have seen that a C program is a set of statements which are normally executed sequentially in the order in which they appear. This happens when no options are available. During programming, we have a number of situations where we may have to change the execution of statements on certain conditions, or repeat a group of statements until certain  specified conditions are met. This involves a kind of decision making to see whether a particular condition has occured or not and then  direct the computer to execute certain statements accordingly.
 C language supports the following statements to possesses such decision making capabilities.

 i)   if statement
 ii)  switch statement
 iii) Conditional operator statement
 iv)  goto statement

These statements helps in decision making, so these are called as decision making statements. Also these statements controls the flow of execution ,so they are also known as control statements.

There are five main component of C language :- 1. The character set: Any alphabet ,digit or special symbol ,used to represent information is denoted by character. The character in C are grouped into four categories:- i) Letters A...Z and a...z ii) Digits 0,1,2,.....9 iii) Special Symbol ~ ` ! @ # $ % ^ & * () . < > ? / " : ; { }[ ]. iv) White Space,blank space, Carriage return, form feed, newline, horizontal tab. C uses the uppercase letter A to Z, the lowercase letters a to z, the digits 0 to 9, and certain special characters as building blocks to form basic program elements ( e.g., constants, variables, operators, expressions, etc. Some of the special characters are listed below: + - * ~ % / & ( ) { } [ ] ? " < > ! ; : Most versions of the language also allow certain other characters, such as @ and $, to be included within strings and comments. C uses certain combinations of these characters, such as \b,\n and \t, to represent spe

Decision making using if statement

Image
The if statement is a powerful decision making statement and is used to control the flow of execution of statements. It's a basically two way decision statement and is used in conjuction with an expression. It's syntax is:- "if(test expression)" It allows the computer to evaluate the expression first and then, depending on condition, it transfers the control to a particular statement. This point of program has two paths to follow,one for the true and other for false condition.As shown in figure:-     Practical examples of if statement:- 1. if(bank balance is < 500)     deposit money 2. if(room is dark)     put on lights The if statement may be implemented in different forms depending on the complexity of conditions to be tested. The different forms of if statements are:- 1.Simple if statement 2.if....else statement 3.Nested if....else statement 4. else if ladder 1.Simple if statement.  The general form of simple if statement is
