To master the C programming language, you need to get a grip on operators and expressions. C uses symbols called operators to perform operations on variables and constants. These operators come in handy when you want to manipulate data and create expressions. An expression is a mix of operators, constants, and variables that boils down to a single value. Key Operators in C Language: Arithmetic Operators: The C language uses arithmetic operators to do basic math. These include adding (+) taking away (-), times (*), divide (/), and finding remainders (%). Relational Operators: When you want to compare two things in C, you use relational operators. They give you a yes or no answer. Are these two identical?" (==), "Is this different from that?" (!=), "Is this bigger than that?" (>), and "Is this smaller than that?" (<). Logical Operators: Logical operators in C help you link different conditions. They figure out how these conditions fit together. You can use "and" (&&) to check if two things are true, "or" (||) to see if at least one thing is true, and "not" (!) to flip a condition. Bitwise Operators: Bitwise operators work on the bits of whole number operands. The operations that fall under this category are bitwise AND (&), bitwise OR (|), bitwise XOR (^), bitwise NOT (~), left shift (<<), and right shift (>>). Assignment Operators: Assignment operators give values to variables. The basic assignment operator is (=). Compound assignment operators like (+=, -=, *= /=) do the operation and give the result in one step. Other Operators
