C# Operators and Expressions | C# Logical Operators | C# Tutorial For Beginners | Simplilearn

hey everyone i am pepper khandelwal and i welcome you all to our simply learned youtube channel today we will talk about one of the interesting topics that are operators and expressions in c sharp but before we begin let me tell you guys we have daily updates on multiple technologies so if you are a tech geek in a continuous hunt for a latest technological advancement then consider getting subscribed to our youtube channel and don't forget to hit the bell icon below so you never miss an update on simply launch youtube channel now without any further ado let's get started with the agenda for today's session we will begin a session with what are operators then we will learn about what an expression is now we will dive into the types of operators then we will discuss the precedence and operators finally we will wind up this session within implementation in a code editor let's get started with what a operator is operators are symbols that can be used to perform operations on operands and a brand can be a variable or a constant operators are used to manipulate variables and values in c sharp c sharp has several operators that are classified based on the operations they perform now let's discuss expressions an expression in c sharp is made up of operands that are variables literals methods calls and operators an expression must have at least one operand but can have zero or more operators an expression statement is an expression followed by a semicolon now let's have a look at the types of operators there are five types of operators in c sharp first assignment operator then arithmetic operator relational operators logical operators and urinary operators now let's discuss them in detail first up assignment operator when assigning values to variables the assignment operator that is equal is used and use the syntax for that next arithmetic operator arithmetic operators are used to carry out the arithmetic operations like addition subtraction multiplication and division and here's the syntax for that next relational operators when comparing two operands the relational operators are used if the relationship is true then the result will be true otherwise it will be false and here is the syntax for that then logical operators to perform logical operations logical operators such as and and or are used based on boolean expression the logical operator returns boolean values true and false logical operators are used in decision making and loops and here's the syntax for that at last urinary operator the urinary operator unlike other operators have only one operand and here's the syntax for that now let's discuss the operator precedence in an expression with multiple operators the operators with the highest precedence are evaluated first when an operand is between operators of the same precedence then the order of operation is determined by associativity with the operator now let's try these operations in a code editor let's start by creating some variables in x comma y let's try the assignment operators first so we can assign an operator by using equal sign so we will assign the 10 value to x let's try to print it x equals to then we will do plus x simultaneously we can also assign the value of x to y by the same method let's try to print y as well so console dot write line y is equals to plus y let's run this first save then execute as you can see it's getting x is equal to 10 and when we define y is equals to x then it is showing y is equals to 10. now let's try to do arithmetic operations for that we will need another variable called res we will delete these operations or rather we will comment them out and we will give y equals to 5 let's try the addition operator so res will be equals to x plus y we will now try to print it console dot right line so x x plus y here plus undress let's do the same thing let's delete this command to make the make it easy let's copy the last two statement and paste it now we will change plus to minus and multiplication and division now let's try to print it first save it and then we will print it here as you can see the x is equal to 10 and y is equal to 5 so x plus 5 it is printing 15 and x minus y is representing 5 then x multiplied by 5 that is 5 multiplied by 10 is 50 and then x divided by y that is 10 divided by 5 is 2. now let's try relational operators so first we will define a boolean variable that will be value 1. now we will store the value 1 is equals to embraces x double equals to y now this text if the x is equals to y since x and y are two different numbers that is 10 and 5 so it will show us false so to print that console dot write line x greater than x equals to y will return plus value 1 let's try this same operation for the cases of greater than and less than let's save this and run it as you can see the x is equal to equals to 5 is returning false because 10 is not equal to 5 for the x greater than y that is 10 is greater than 5 so it returns true and vice versa it will return false for the lesser terms now let's comment these out as well now let's try logical operators so we'll again define the x equals to 30 and y is equals to 10. first we will try the or operator let's clip this out paste it here so that we can use this value and operation again so for the or operator we will use value 1 is equals to f x is equal to equals to y and the or or is a vertical dash or x is greater than 5 so in case of x either one of the condition must be true then it will return true so since x is equal to equals to y is false which we have already done that here so now the x if x is greater than 5 then it will also return true so to check that we will print console dot write line value one let's do it for the end operator as well so the value let's copy paste it this time we will remove these vertical dashes to and and operator let's save it and run it as you can see in the first case we are using an or operator in which either one of them is required to be true to get a true answer since x is greater than 5 is a true answer so it is giving us a true answer but in case of the end operator both of them needs to be true for it to give true since x equals to equals to y was false which we have checked in our relational operation experiment so now this will give us the false answer now let's try and do urinary operators let's take a different variable so end z equals to 10 comma a value 2 and a boolean that is flag which is equals to true now first try so value 2 is equals to plus 3 now we will print these start right line plus z is equals to comma plus value two let's copy paste them and change these values now we will use minus z here also minus send another operation where we will use double plus now we will use minus and for the last one we will use console dot writeline and we will print the negation of flag since flag is defined as true so this one should show flag as false let's run this as you can see it is showing the plus that equals to ten and minus that is equals to negative ten the plus two z increment the value by one then minus minus z decrement the value by 1 so since plus plus z was already 11 so minus minus z just decreased it to 10. now the flag is showing true because i haven't used the negation symbol here so now let's add the negation symbol and save it and then run it back here now it's showing the false now let's get back to our slide and this was all for today's session hope you guys found it informative and helpful if you liked this session then like share and subscribe if
