If Statement in C

Hello Friends,

Today we will discuss about C language Statements.

There are two types of Statements in C language.

1.Selection Statements or Decision Statements
2.Iteration Statements or Control Statements


Selection Statements : Selection Statements  executes different sections of code depending on a specific condition or the value of a variable.There are two types of selection statements :

• If - else
• Switch-case  

lets see an example :

Here, We are finding greatest number from 2 numbers using if statement..

Here we are finding greatest number among 3 numbers using If Statement with the help of logical operator(AND).

 If Statements is used to compare two operands .It can take multiple condition using logical operators.
 If Statement can be categorized in different ways - If-else, ElseIf,NestedIf,MultipleIfs etc...

Lets take another example

A program to display greatest number among three numbers.

Lets take some more examples of If Statements

Here we are using else if statement .

A program to display total marks ,average and grade of a student.

Note:
scanf () function is used to accept input from users. For integer values we use '%d' format specifier.
When user input some value it stored into the variable i.e given as '&variable_name' . '&' symbol would be always used with variable name because it stores the address of memory . We call '&' symbol as 'AddressOf' operator in C language that stores the variable memory location.

 we will continue  with if Statements Program.

Lets take an another example of If Statement with  Operators(Logical,Relational).

A program to find average of six subjects and display the results.

Average	Result
>=35 and <50	Third Division
>49 and <60	Second Division
>=60 and <75	First Division
>=75 and <=100	Distinction
<35 or if marks in any subject less than 35	Fail

A program to calculate the gross salary for the conditions given below.

Basic Salary (Rs.)	DA (Rs.)	HRA (Rs.)	Conveyance (Rs.)
>=5000	110% of Basic	20% of Basic	500
bs>=3000 && bs<5000	100% of Basic	15% of Basic	400
bs<3000	90% of Basic	10% of Basic	300

Output:
