An Integrated Development Environment typically consists of: - correct answer Text editor, compiler, debugger Programmer-defined names of memory locations that may hold data are: - correct answer Variables According to orientation clip how many hours is required for successful completion of this course? - correct answer 180 hours A CPU really only understands instructions that are written in machine language. - correct answer True A(n) ____________ is a set of instructions that the computer follows to solve a problem. - correct answer Program This is a complete instruction that causes the computer to perform some action. - correct answer Statement According to orientation clip how many EXAMs (excluding FINAL) are there in this course? - correct answer 3 According to orientation clip what grade do you get for lab assignments missed their due dates? - correct answer 0 The purpose of a memory address is: - correct answer to identify the location of a byte in memory Three primary activities of a program are: - correct answer Input, Processing, and Output The ________ decodes an instruction and generates electrical signals. - correct answer control unit During which stage does the central processing unit analyze the instruction and encode it in the form of a number, and then generate an electronic signal? - correct answer decode A set of well-defined steps for performing a task or solving a problem is known as a(n): - correct answer Algorithm In a broad sense, the two primary categories of programming languages are: - correct answer low-level and high-level This step will uncover any syntax errors in your program. - correct answer Compiling During which stage does the central processing unit retrieve from main memory the next instruction in the sequence of program instructions? - correct answer Fetch In C++, key words are written in all lowercase letters. - correct answer True According to orientation clip what happens if you missed an EXAM due to conditions that you could not control? - correct answer The final exam can replace the zero This is a set of rules that must be followed when constructing a program. - correct answer Syntax _______________ are used to translate each source code instruction into the appropriate machine language instruction. - correct answer Compilers True/False: Escape sequences are always stored internally as a single character. - correct answer True Every complete C++ program must have a ________. - correct answer function named main Which of the following defines a double-precision floating point variable named payCheck? - correct answer double payCheck Character constants in C++ are always enclosed in ________. - correct answer single quotation marks In programming terms, a group of characters inside a set of quotation marks is called a(n): - correct answer string literal True/False: The C++ language requires that you give variables names that indicate what the variables are used for. - correct answer false Besides decimal, two other number systems you might encounter in C++ programs are: - correct answer hexadecimal and octal True/False: A variable called "average" should be declared as an integer data type because it will probably hold data that contains decimal places. - correct answer False True/False: When writing long integer literals or long long integer literals in C++ 11, you can use either an uppercase or lowercase L. - correct answer True Which one of the following would be an illegal variable name? - correct answer 3dGraph In a C++ program, two slash marks ( // ) indicate: - correct answer A comment In C++ 11, the ________ tells the compiler to determine the variable's data type from the initialization value. - correct answer auto keyword Which character signifies the beginning of an escape sequence? - correct answer A variable's ________ is the part of the program that has access to the variable. - correct answer scope True/False: Floating point constants are normally stored in memory as doubles. - correct answer True In memory, C++ automatically places a ________ at the end of string literals. - correct answer Null terminator Of the following, which is a valid C++ identifier? a. Junē997 b. _employee_number c. ___department d. myExtraLongVariableName e. All of the above are valid identifiers. - correct answer all Which escape sequence causes the cursor to move to the beginning of the current line? - correct answer r A statement that starts with a # symbol is called a: - correct answer . Preprocessor directive The ________ causes the contents of another file to be inserted into a program. - correct answer #include directive A variable whose value can be either true or false is of this data type. - correct answer bool Assuming you are using a system with 1-byte characters, how many bytes of memory will the following string literal occupy? "William" - correct answer 8 These are used to declare variables that can hold real numbers. - correct answer - Floating point data types
