[Face problem] The first order of C symbols

• int x = 0;if (x = 0 | | x = = 0) printf ("%dn", x);p rintf ("%dn", X);

• The priority table for reference C is actually if (x = (0 | | x = = 0))
  Will printf out two 1.
  

  Operators of the same precedence, the order of operations is determined by the binding direction.

  Simple note is:! > Arithmetic operators > Relational operators > && > | | > Assignment Operators

  C Operator Precedence Table

  This

  page lists C operators the order of precedence (highest to lowest). Their associativity indicates in what order operators of equal precedence in an expression is applied.

  Operator	Description	Associativity
  ( ) [ ] . - ++ --	Parentheses (function call) (see Note 1) Brackets (array subscript) Member selection via object name Member selection via pointer Postfix increment/decrement (see Note 2)	Left-to-right
  ++ -- + - ! ~ (type) * & sizeof	Prefix increment/decrement Unary Plus/minus Logical Negation/bitwise Complement Cast (convert value to temporary value of type) Dereference Address (of operand) Determine size in bytes on this implementation	Right-to-left
  *  /  %	Multiplication/division/modulus	Left-to-right
  +  -	Addition/subtraction	Left-to-right
  << >>	Bitwise shift left, Bitwise shift right	Left-to-right
  < <= > >=	Relational less than/less than or equal to Relational greater than/greater than or equal to	Left-to-right
  ==  !=	Relational is equal to/is not equal to	Left-to-right
  &	Bitwise and	Left-to-right
  ^	Bitwise Exclusive OR	Left-to-right
  |	Bitwise inclusive OR	Left-to-right
  &&	Logical and	Left-to-right
  | |	Logical OR	Left-to-right
  ? :	Ternary conditional	Right-to-left
  = +=  -= *=  /= %= &= ^=  |= <<= >>=	Assignment Addition/subtraction Assignment Multiplication/division Assignment Modulus/bitwise and Assignment Bitwise exclusive/inclusive OR Assignment Bitwise Shift Left/right Assignment	Right-to-left
  	Comma (separate expressions)	Left-to-right
  Note 1: parentheses A Re also used to group sub-expressions to force a different precedence; Such parenthetical expressions can be nested and is evaluated from inner to outer. Note 2: Postfix increment/decrement has high precedence, but The actual increment or decrement of the operand is delayed (to be accomplished sometime before the statement completes E xecution). So in the statement  y = x * z++;  the Current value of  z  is used to evaluate the expression ( i.e., &nbs P z++  evaluates to  z ) and  z  only incremen Ted after all else was done. see  postinc.c  for Another example.
