I feel that my C language has been well learned. Others also say that my c is okay, but I went to the interview today. Although all the questions are existing on the internet, I made a mistake when I showed it to their technicians. When I looked at

1. The "side effect" of the constant equals symbol of the Three-object Operator" # Include int main (INT argc, char * argv []) { int A = 1; int B = 2; int c = 3; A = B> C? B: C; // The maximum value of BC. A = 0? B: C; // obtain the value

I went to the test yesterday and made two hours of questions, including three parts. The first part isC LanguageBasic, the second part isCodeReview is to give you someProgramSegment to indicate which line will go wrong, The third part is the basic
