cmath

Which statement will read an entire line of input into the following string object? string address; 1. cin << address; 2. getline(cin, address); 3. cin.get(address); 4. None of these 5. cin address;

getline(cin, address);

In any program that uses the cin object, you must include the ________. 1. linker 2. >> and << operators 3. None of these 4. iostream header file 5. compiler

iostream header file

This manipulator is used to establish a field width for the value immediately following it.

setw

When this operator is used with string operands it concatenates them, or joins them together. 1) & 2) % 3) + 4) * 5) None of these

+

True/False: Arithmetic operators that share the same precedence have right to left associativity.

False

False

True/False: The fixed manipulator causes a number to be displayed in scientific notation.

False

True/False: When a program uses the setw manipulator, the iosetwidth header file must be included in a preprocessor directive.

False

When the final value of an expression is assigned to a variable, it will be converted to:

The data type of the variable

True/False: The only difference between the get function and the >> operator is that get reads the first character typed, even if it is a space, tab, or the [Enter] key.

True

This statement will pause the screen, until the [Enter] key is pressed.

cin.get();
