Exam 12: More on C-Strings and the String Class

The expression ^{str1 < str 2} is true when

The ^>> operator can be used to convert a value of type double to an equivalent string object stored in memory.

Assume that ^str1 and ^str2 are objects of the string class. The proper expression to use when comparing them for equality is

The code ^{int x = 0; while (s[x] != 0){ x++;}}

An array of characters ending with the null terminator is called

The following statement declares a ^string object and initializes it to ^{"Once upon a time"}. string theString("Once upon a time");

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

There exist C++ stream classes that write and read in- memory strings.

To use the ^strlen function in a program, you must ^#include

The ^itoa function is similar to ^atoi, but it works in reverse.

The function converts a C- string to an integer and returns the integer value.

A good way to convert a value of type double to a string is

The null terminator stands for the ASCII code

After ^{num = atoi("1000");} executes, what value is stored in the variable ^num?

The string class member function will return the number of characters in the string object.

To account for the null terminator stored at the end of each C- string, the ^strlen function returns the number of characters in its argument, plus one.

The C++ compiler performs strict array bounds checking whenever an array of characters is being accessed.

The expression ^{strcmp("ab", "cde")} returns
