SOLUTION
010.0540 If I declare something as the data type
char (character) how is it that I am able to misuse a print specifier
(i.e., print it out as a short, an integer, a long, or a float)?
SEE SOLUTION
010.0560 Suppose
that a section of RAM appeared as:
|
4058 |
4059 |
4060 |
4061 |
|
10010010 |
11001011 |
01011001 |
00010010 |
I issued the commands: long longvar;
printf(“%lu”, &longvar);
And I received the output: 4058
What would I get as output if I entered the command:
printf(“%ld
%lu %d %c”, longvar, longvar, longvar, longvar);
(Note: Let’s assume that integers are still 16-bits
long, so %d interprets accordingly)

the values of 21 through 210??

an infinite loop and what is an example of one in a for
statement?
014.0000 What is
a while
statement used for and how do they work?

might I use a while statement to print out only the even values of the integers beween
1 and 100?
014.0100 What is
the difference between a while statement and a do .. while
statement? Which is generally preferred?
014.0130 How
might I use a do .. while
statement to print out the octal and hexadecimal values of the integers beween 1 and 500?
014.0150 Can
infinite loops take place using either a while statement or a do .. while
statement? What are some examples?

they, and how are they called and used?

necessary?

does the return statement do? Is it necessary?
020.0300 What
are the benefits of using functions?
020.0350 What
are the differences between local and global variables? Is one preferred over
the other? Why?
020.0370 Why is
it that I can use the same variable name in two different functions?
020.1000 How
might I write a program to print the squares of all of the even integers
between 1 and 100 and all of cubes of the odd integers between 1 and 100 using
functions?
020.1005 Are
there different functions that could be written to produce the same output as
above? What are some of them?
020.1010 If I
used global variables instead of local variables, how different would the

100.0100 Given the following
C/C++ program:
#include
<iostream.h>
// The standard I/O header file
void
main()
{
char clocation1 = 'D', clocation2 = 10;
int ilocation1 = '3', ilocation2 = 5;
float flocation1 =
7.5, flocation2 = 5.0;
cout << clocation1 +
clocation1/clocation2 * clocation2;
cout << endl;
cout <<
ilocation1++/ilocation2 + ilocation1 - ilocation2 * 3 + 8;
cout << endl;
cout << ilocation1 +
ilocation1 * 2 + ++ilocation2 % 2 - 4;
cout << endl;
cout << flocation1 +
flocation1 / flocation2 * 2;
cout << endl;
}
A. What would be displayed
by the line:
cout
<< clocation1 + clocation1/clocation2 * clocation2;
B. What would be displayed
by the line:
cout
<< ilocation1++/ilocation2 + ilocation1 - ilocation2 * 3 + 8;
C. What would be displayed
by the line:
cout
<< ilocation1 + ilocation1 * 2 + ++ilocation2 % 2 - 4;
D. What would be displayed by the line:
cout
<< flocation1 + flocation1 / flocation2 * 2;
100.0110 A quick note before we begin this question.
The following program will run in C/C++. However, the output might seem a
little strange, at first. If a logical statement evaluates to
‘TRUE”, a “1” will be printed. If it evaluates to “FALSE” a “0” will be
printed out. Keep this in mind when answering the following questions.
Given
the following C++ program:
#include <iostream.h>
void main()
{
short a = 1, b = 2, c = 3, d =
4, e = 5;
cout
<< ((a > b) || (e > d));
cout
<< endl;
cout
<< ((a > b) && (e > d));
cout
<< endl;
cout
<< ((b == 2) && (d > 4) || (e == 4) || (c > b));
cout
<< endl;
cout
<< ((b + 1 >= c) || (d / 2 == 0) && (e % 3 == 0));
cout
<< endl;
cout << ((a + b > d) && (c++ * b >
b + e) || (e - d == a));
cout << endl;
cout
<< ((++a >= b) && (c - a == b) || (c % b == 0));
cout
<< endl;
}
A. What would be printed out
by the statement:
cout << ((a > b) || (e > d));
B. What would be printed out by the statement:
cout << ((a > b) && (e > d));
C. What would be printed out
by the statement:
cout << ((b == 2) && (d > 4) || (e == 4)
|| (c > b));
D. What would be printed out
by the statement:
cout << ((b + 1 >= c) || (d / 2 == 0) &&
(e % 3 == 0));
E. What would be printed out
by the statement:
cout
<< ((a + b > d) && (c++ * b > b + e) || (e - d == a));
F. What would be printed out
by the statement:
cout << ((++a >= b) && (c - a == b) ||
(c % b == 0));

Given the following C program, show the output that would be produced
#include <stdio.h>

r6 = z -
(float) b * z/y;
printf("Output

Output F = SEE SOLUTION
r7 = (int) (x + y) - f;
printf("Output

if ((b < d) && (h % 2 == 1))
printf("Output

printf("Output H = FALSE\n");
