Do not use the assignment operator in the following cases contexts because it typically indicates programmer error and can result in unexpected behavior:
- Controlling expression of
if,switch(selection statement (controlling expression) while(controlling expression)- Controlling expression of
while,do ... while(iteration statementcontrolling expression) - S
econd operand of for(iteration statementsecond operand) - First operand of
?:(selection statementfirst operand) &&(either operand)- Either operand of
||or&&(logical operators) - comma operator (second operand) Second operand of comma operator when the comma expression is used in any of these contexts
