Hello everyone, today I'm going to present on operators in C, the building block of expression. Operators are very important in C because they allow us to perform calculations, make decisions and control how data behaves in a program. Let's understand them step by step. What are operators? Operators are special symbol that perform operations on variables and values. For example, symbolic, plus, minus and equal to our operators. Their purpose is to perform calculation. Compare values and transform data. When we use operator properly, our code become more concise and efficient. Does are divided based on the number of operands they use. First, unary operators, they work on single operand. Second binary operators they work on 2 operands. Third, new operator it works on three operands. It using the format condition expression one expression 2. So now understanding how many operands and operator use help us predict how expression will behave. Arithmetic operators. This include addition, subtraction, multiplication, division. Modulus. We also have unary plus and minus for sign changes. One important thing is to understand integer division and floating point division. Also prefix and postfix increment operators behave slightly different in expressions. Talking about relational operators, they help us in comparing values. They always return true or false. And talking about logical operators, they combine conditions logical and logical OR and logical not these uses. Something called short circuiting. For example in and if the first condition is false, the second one is not checked. Talking about assignment operator, assignment operator stores a value in variable for example equals to five and these operator make our code shorter and clearer. For example A equals to three is same as A to a three. Bitwise operator worked directly on binary bits, bitwise AND, bitwise OR, bitwise left shift and right shift. These are commonly used in embedded system, low level programming and performance sense sensitive applications. Talking about special operator, the scoop resolution operator is used to assess clickable variables or namespace member formatting manipulators. Are they helping control output formatting? It is better to use and instead of NFL in performance sensitive loops because endl flushes the output stream. Talking about turn your operator, ternary operator is a short form of if else it is concise and returns a value directly. However for complex condition. Angular if else is clear. Let's summarize. To summarize, understand the operator category by unary, binary and ternary. Choose appropriate operator depending on the task which you are doing. Practice and review operators. Precedence and behavior Operators are fundamental tools in C Mastering them help us to write our code. Clearer, safer and more efficient programs can be created. Thank you.
