Solution: 1) In the above expression, the highest precedence operator is (). are scheduled with the Round-Robin time sharing method. asked Feb 19 in General by Akshatsen (29.9k points) c; data-types; operators-and-expressions-in-c; Certain operators have higher precedence than others; for example, the multiplication operator has higher precedence than the addition operator: For example x = 7 + 3 * 2; here, x is assigned 13, not 20 because operator * has higher precedence than +, so it first gets multiplied with 3*2 and then adds . Associativity also affects grouping of operators and operands when you have multiple operators of the same precedence - the expression is parsed as because the operator (along with the other arithmetic operators) is left-associative . Short-circuiting allows conditional operators to take precedence over the grouping operator. As another example, the unique exponentiation operator has right-associativity, whereas other arithmetic operators have left-associativity. There are many arithmetic operators in the C language, and the order of precedence is applicable for them too. In programming language theory, the associativity of an operator is a property that determines how operators of the same precedence are grouped in the absence of parentheses. This affects how an expression is evaluated. [5] The table given here has been inferred from the . Operators that are in the same cell (there may be several rows of operators listed in a cell) are grouped with the same precedence, in the given direction. As we discussed above first precedence given to parenthesis ( ()). Precedence is determined by operators only. Q: 19.CALL [BX] is : a. 2) Now, /, * and % operators have the same precedence and highest from the + and - Here, we use the associativity concept to solve them.
