On the other hand, right-to-left associativity pertains to the evaluation of operators from the right side of the expression to the left. An example of this is the assignment operator =, which has right-to-left associativity. Thus, in the expression a = b = c, the assignment is executed...
The operator precedence determines which operator is to be first evaluated and which next in expression when one or more operators present in an expression. the other term which is related to expression is operator associativity. Operator associativity which determines the direction of operator evaluatio...

int a = 2, b = 3, c = 5; double f = 4.5; double res = a + b / f + c; In the last line of code, we can see that three variables are type int, and one is type double. According to the operator precedence, / will be the first evaluated; in this expression, b/f mean...
C++ Operator Precedence TableThe operators are listed from top to bottom in descending order of precedence:OperatorDescriptionExample () [] -> . Function call, Subscript, Member access arr[0], obj.method(), ptr->member ++ -- Increment/Decrement x++, --y ! ~ - + Logical/Bitwise NOT, ...
Take a look ata = 4;statement. The associativity of the=operator is from right to left. Hence, the value ofbis assigned toa, and not in the other direction. Also, multiple operators can have the same level of precedence (as we can see from the above table). When multiple operators of...

When number of operators occurs in an expression the operator which is to be evaluated first is judged by applying priority of operators. The arithmetic operators available in C are + used for Addition - used for Subtraction * used for Multiplication /
The operands a - b and c + d have a rank 11. Using the precedence of an expression and its subexpression, the MISRA C:2012 standard recommends:Enclose the operands of sizeof operator in parenthesis. Enclose an operand of an expression in parenthesis if all these conditions are true: The...
