a + b * c Would multiply b * c first, then add a to the result. Using Parentheses Use parentheses to change the order in which an expression is evaluated. a + b * c Would multiply b * c first, then add a to the result. If you really want the sum of a and b to be multipl...
Enumerations. Andy Wang Object Oriented Programming in C++ COP 3330 Chapter 14 Bitwise Operators Objectives Bitwise Operations C includes operators that permit working with the bit-level representation of a value. You can: - shift the bits of a value to the left. Homework Finishing Chapter 2 of...
It is hard to remember the complex priority relation of the operators in C programming language. This paper presents the skilful rules to remember the priority of C language operators according to the programming and teaching practice. The application of the rules is demonstrated by two examples.年...
Bits as binary flags. Finally, I’d like to print out a list of all of the students that took exam 1. int which = 1; for (int i=0; i<32; i++) { if (quiz1 & which) //OK in C/C++ only printf( “student %d took the quiz. \n”, i ); which <<= 1; } ...
