C Operator Precedence
Precedence and associativity are independent from order of evaluation. The standard itself doesn't specify precedence levels. They are derived from the grammar. In C++, the conditional operator has the same precedence as assignment operators, and prefix ++ and --and assignment operators don't have the restrictions about their operands.

The above two assignments are actually not sequenced and can happen in any order, meaning that . t = (U) X; u = X; ... (Note that this sequencing freedom is specific to C language, in which the result of an assignment in an rvalue. In C++ assignment evaluates to an lvalue, which requires "chained" assignments to be sequenced.) ...
Precedence and order of evaluation
Sequential evaluation. Left to right. 1 Operators are listed in descending order of precedence. If several operators appear on the same line or in a group, they have equal precedence. 2 All simple and compound-assignment operators have equal precedence. An expression can contain several operators with equal precedence.
C Precedence And Associativity Of Operators
Precedence of operators. The precedence of operators determines which operator is executed first if there is more than one operator in an expression. Let us consider an example: int x = 5 - 17* 6; In C, the precedence of * is higher than - and =. Hence, 17 * 6 is evaluated first. Then the expression involving - is evaluated as the precedence of ...
Operator Precedence and Associativity in C
The concept of operator precedence and associativity in C helps in determining which operators will be given priority when there are multiple operators in the expression. It is very common to have multiple operators in C language and the compiler first evaluates the operater with higher precedence. It helps to maintain the ambiguity of the ...
Order of evaluation
Order of evaluation. Order of evaluation of the operands of any C operator, including the order of evaluation of function arguments in a function-call expression, and the order of evaluation of the subexpressions within any expression is unspecified (except where noted below). The compiler will evaluate them in any order, and may choose another ...
Assignment Operators in C
1. "=": This is the simplest assignment operator. This operator is used to assign the value on the right to the variable on the left. Example: a = 10; b = 20; ch = 'y'; 2. "+=": This operator is combination of '+' and '=' operators. This operator first adds the current value of the variable on left to the value on the right and ...

C Assignment Operators
The assignment operators in C can both transform and assign values in a single operation. C provides the following assignment operators: | =. In assignment, the type of the right-hand value is converted to the type of the left-hand value, and the value is stored in the left operand after the assignment has taken place.
C Programming Assignment Operators
Assignment Operators in C are used to assign values to the variables. They come under the category of binary operators as they require two operands to operate upon. The left side operand is called a variable and the right side operand is the value. The value on the right side of the "=" is assigned to the variable on the left side of "=".
Assignment Operators in C
Simple assignment operator. Assigns values from right side operands to left side operand. C = A + B will assign the value of A + B to C. +=. Add AND assignment operator. It adds the right operand to the left operand and assign the result to the left operand. C += A is equivalent to C = C + A. -=.
Assignment operators
Assignment performs implicit conversion from the value of rhs to the type of lhs and then replaces the value in the object designated by lhs with the converted value of rhs . Assignment also returns the same value as what was stored in lhs (so that expressions such as a = b = c are possible). The value category of the assignment operator is non ...
Assignment and shorthand assignment operator in C
Shorthand assignment operator combines one of the arithmetic or bitwise operators with assignment operator. For example, consider following C statements. int a = 5; a = a + 2; The above expression a = a + 2 is equivalent to a += 2. Similarly, there are many shorthand assignment operators. Below is a list of shorthand assignment operators in C.
6.1
The assignment operators have the second lowest precedence (only the comma operator is lower, and it's rarely used). Therefore, so long as there is only one assignment (and no commas), we know the right operand will fully evaluate before the assignment. ... The compiler is free to evaluate operands a, b, c, or d in any order. The compiler is ...

Yankees designate pitcher Tonkin for assignment, four months after
NEW YORK (AP) — The New York Yankees shuffled their bullpen Sunday, designating Michael Tonkin for assignment and selecting the contract of Phil Bickford from Triple-A Scranton/Wilkes-Barre. Tonkin was 3-2 with a 3.38 ERA in 39 appearances since being claimed off waivers from the New York Mets on April 26. Tonkin posted a 1.84 ERA in his ...
Order of evaluation of assignment statement in C++
Expression evaluation order is a recurring discussion topic in the C++ community. In a nutshell, given an expression such as f(a, b, c), the order in which the sub-expressions f, a, b, c are evaluated is left unspecified by the standard. If any two of these sub-expressions happen to modify the same object without intervening sequence points ...

C++ Operator Precedence
In C, the ternary conditional operator has higher precedence than assignment operators. Therefore, the expression e = a < d ? a ++: a = d, which is parsed in C++ as e = ((a < d)? (a ++): (a = d)), will fail to compile in C due to grammatical or semantic constraints in C. See the corresponding C page for details. See also

How to make a C assignment depending on order of operands
CPUs are different. On some it might make sense to do things in one order. On another that same order will be extremely slow, but doing things in another order is very fast. Maybe the next generation of a CPU will change how instructions are executed and now that third order of operations makes the most sense.
