Exam 10: Characters, C-Strings, and More About the String Class

You may use the <, >, <=, >=, ==, and != relational operators to compare string objects.

What is the output of the following statement?

"Whitespace" encompasses which of the following?

A test using the isupper function will return false if the argument is an uppercase character.

To test whether a character is a numeric digit character, use this function.

The ftoa function converts a floating-point value to an ASCII value.

To determine whether a character is whitespace, use this function.

The isdigit function will return a true if its argument is a digit between 0 and 9.

If a C-string that cannot be converted to a numeric value is passed to the atoi function, the function's behavior is undefined by C++.

To use the strlen function in a program, you must also write #include ________.

This function accepts pointers to two C-strings and an integer argument, which indicates how many characters to copy from the second C-string to the first.

A library function that can find one C- string inside another is:

Look at the following statement. The expression being tested by this statement will evaluate to true if var1 is:

If an uppercase character is passed as an argument to toupper, the result will be an uppercase character.

Although C++ provides ample library functions to handle numeric values, we must write all of our own functions to manipulate character values.

The statement: char var1 = tolower $\left(^{\prime} A^{\prime}\right)$ Will result in:

The strlen function returns a C-string's length and adds one for \0.

This function will return true if its argument is a printable character other than a digit, letter, or space.

The C++ library provides functions for converting a string representation of a number to a numeric data type, and vice-versa.

The C++ compiler performs strict array bounds checking when it encounters an array of characters.
