Question 1

The standard C library consists of 5 header files.

Accepted Answer

The standard C library consists of more than 5 header files, including stdio.h, stdlib.h, assert.h, math.h, string.h, and many others, covering a wide range of functionalities.

Question 2

Placing the appropriate #include statement at the bottom of the program ensures proper access to the library functions whose prototypes are contained in the header file.

Accepted Answer

The #include statement must be at the beginning of a program or before any usage of the functions or types declared in the header file, to ensure the compiler knows about them during compilation.

Question 3

The rand() function produces a series of random numbers in the range 0 < rand() < RAND_MAX, where the constant RAND_MAX is a compiler-dependent symbolic constant that is defined in the stdlib.h header file.

Accepted Answer

The rand() function generates pseudo-random numbers between 0 and RAND_MAX, inclusive, and RAND_MAX is defined in the stdlib.h header file.

Question 4

Many C compilers have a randomize() routine that is defined using the srand() function.

Accepted Answer

The randomize() routine is often implemented using the srand() function to seed the random number generator in C compilers.

Question 5

The getcharacter() function can be used for single character input.

Accepted Answer

The answer of The getcharacter() function can be used for...

Question 6

There is no C string data type.

Accepted Answer

In C programming, strings are represented as arrays of characters, terminated by a null character ('\0'), rather than a specific "string" data type.

Question 7

A function that is called or summoned into action by its reference in another function is a ____.
A)function prototype
B)called function
C)calling function
D)function declarator

Accepted Answer

A "called function" is the correct term for a function that is invoked or summoned into action by its reference in another function. The function that makes the call is known as the "calling function."

Question 8

A function that calls another function is referred to as the ____.
A)function prototype
B)called function
C)calling function
D)function declarator

Accepted Answer

The function that initiates a call to another function is known as the calling function.

Question 9

A ____ declares the function to the compiler-it tells the compiler the name of the function, the data type of the value that the function will return (the keyword void indicates that the function will not be returning any value), and the data types of each argument that the function expects to receive when it is called.
A)function prototype
B)function header
C)function body
D)function declarator

Accepted Answer

A function prototype serves exactly this purpose: it declares the function to the compiler by specifying the function's name, return type, and the types of its parameters, without detailing the function's actual implementation.

Question 10

When a function simply receives copies of the values of the arguments and must determine where to store these values before it does anything else, this is known as a ____.
A)pass by value
B)pass by reference
C)stub
D)function declarator

Accepted Answer

This is known as "pass by value," where the function receives copies of the argument values, implying that the original data is not modified directly.

Question 11

The purpose of a ____ is to identify the data type of the value returned by the function, if any, provide the function with a name, and specify the number, order, and type of values expected by the function.
A)function declarator
B)prototype
C)function body
D)function header

Accepted Answer

The function header specifies the return type, function name, and parameters, which includes the number, order, and type of values expected by the function.

Question 12

The purpose of a ____ is to operate on the passed data and return, at most, one value directly back to the calling function.
A)function declarator
B)prototype
C)function body
D)function header

Accepted Answer

The purpose of a function body is to contain the actual code that operates on the passed data and returns a value directly back to the calling function. It is where the logic of the function is implemented.

Question 13

The argument names in the header line of a function are known as ____.
A)arguments
B)parameters
C)actual arguments
D)actual parameters

Accepted Answer

Parameters are the argument names listed in the function definition. They are used in the function body to refer to the values passed to the function.

Question 14

The portion of the function header that contains the function name and parameters is known as a ____.
A)function body
B)prototype
C)function declarator
D)stub

Accepted Answer

The function declarator is the part of the function header that includes the function name and parameters, specifying the function's interface.

Question 15

The method for adjusting the random numbers produced by a random-number generator to reside within a specified range is called ____.
A)scaling
B)stubbing
C)prototyping
D)converting

Accepted Answer

Scaling is the correct term for adjusting random numbers to fit within a specific range. This process involves transforming the output of a random number generator so that it falls within a desired interval.

Question 16

___ is an example of a function header line.
A)float roi(int, double);
B)float roi( int yrs, double rate);
C)printf("%f", roi(3, amt));
D)float roi( int yrs, double rate)

Accepted Answer

The answer of ___ is an example of a function...

Question 17

___ is an example of a function prototype.
A)float roi(int, double);
B)roi(3, amt);
C)printf("%f", roi(3, amt));
D)float roi( int yrs, double rate)

Accepted Answer

A function prototype is a declaration of a function that specifies the function's name, return type, and parameters, but not its body. Option A, "float roi(int, double);", matches this definition, declaring a function named 'roi' that returns a float and takes an int and a double as parameters.

Question 18

___ is an example of a calling statement.
A)float roi(int, double);
B)float roi( int yrs, double rate);
C)printf("%f", roi(3, amt));
D)float roi( int yrs, double rate)

Accepted Answer

The answer of ___ is an example of a calling...

Question 19

____ is a prototype of a function that returns no value.
A)void funcA();
B)funcA();
C)int funcA();
D)null funcA();

Accepted Answer

A prototype of a function that returns no value is specified with the void keyword before the function name, hence "void funcA();" is correct.

Question 20

To return a value, a function must use a(n) ____ statement.
A)exit
B)throw
C)break
D)return

Accepted Answer

To return a value from a function, the "return" statement is used. This statement stops the execution of the function and sends the specified value back to the caller.
