Operator in the swift programmign languaga

#Basic Operator in Swift Programming.

Operator is special symbol that is use to change , combine and perform the task on the given value. For example ( + ) is arithmetic operator use to add two numbers.

Swift gives almost all the operator that is present in the c programming language. Swift provide the range operator that is not present in the c programming. 1…2 , a..<b , it is used to show the range of value.

In this blog we are going to see common  operator and learn to use them and try to  build programming_idea.

Terminology

There are tree type of the operator in all the programming language , unary , binary and ternary.

·       unary operator is performed operation on the single operand.( - a ) , unary prefix operator need just before(!a) the operand and unary postfix operator need to keep just  after the operand(a+)

·       Binary operator need two operand to perform the operation. It is keep between the two operand ex ( a + b) , ( a – b)

·       Ternary operator need two operand to perform the operation . ternary operator is used to remove the use of if , else statement . (a ? b : c)

Assignment Operator:

Assignment Operator is use to assign and update  the value in the variable ,

a = 5

b = 6

a = b

// now a is equal to the 6 because we assign the value of b in the a so the value of  a is replace with the value of b.

With the help of assignment operator we also assign the value of the tuple

Ex –

let (a , b) = (20 , 30)

this is the tuple here 20 assign to the a and 30 to b

in the swift programming we can not use the assignment operator in the if , else condition statement . it is strictly prohibited .

if a = b {

}

This is not valid in the swift programming we you assign value like this it is going to give the error.

Arithmetic operator 

Swift provide four standard arithmetic operator for all the numbers in the swift.

• Addition (+)
• Subtraction (-)
• Multiplication (*)
• Division (/)

 1 + 2  = 3

10 – 2 = 8

2 * 22 = 44

40 / 5 = 8

Along with this four standard operator there is also a operator the is reminder ( % )operator that is also present in the c programming language present in the swift programming language.

Reminder operator is use to get the reminder of the value .

 72 % 3 = 0

 9 % 2 = 1

Unlike the arithmetic operators in C and Objective-C, the Swift arithmetic operators don’t allow values to overflow by default. You can opt in to value overflow behavior by using Swift’s overflow operators (such as a &+ b)

Addition operator is also used for the concatenation of two strings.

Unary ( + ) operator 

Unary ( + ) operator is not change the value it is same as with the ( + ) mark there is no difference with a number having or not having the unary ( + ) operator.

 a = 6

a = +6

although the unary (+) don’t do to anything but we use this when we in the operation there is negative number present.

Some basic program to understand the Arithmetic operator:-

Print the sum of given Two numbers:

var a = 10

var b = 20

print( a + b)

// 20

Subtract the a from b

Print ( “the value after subtracting a form b = “b – a)

//the value after subtracting a from b = 10

Write a program to find the average of the 5 numbers:

var a = 10

var b = 5

var c = 8

var d = 12

var e = 6

var sum = a + b + c + d + e

var average =  sum / 5

print (average)

# program to build the programmingIDEA

Print the value of a

A = 5 + 6 – 4 *2

Print(A)

// 3

Print the value of z

Z = 70 / 5  * 2

Print(Z )

//28

Print the value of I;

I = 14 % 3 + 5 – 2

Print(I)

// 5

This is all about the operator in swift programming language and this is not the all operator of the swift in this blog only the assignment and arithmetic operator are cover by me for the further operator in swift follow my blog.

I write these blog to increase the ProgrammingIdea of the freshers.
