1. Enroll a student identified by her snum into the class named 'Introduction to Database Systems'.

<u>Explanation:</u>

Since enroll is unique in the university enrollment database schema and field name is SNUM and it is data type is an integer. To identify student class name and department name and name of student SNUM field is used for searching in university enrollment database schema. Enrollment changing is not possible of the student’s not possible or not good practices in university enrollment database schema.

12. Write C statement(s) that accomplish the following. a. Declare int variables x and y. Initialize x to 25 and y to 18. b. Dec

saul85 [17]

Answer:

int x = 25;

int y = 18;

int temp = 10;

char ch ='a';

x += 5;

double payRate = 12.5;

int tempNum = firstNum;

int tempp = x;

x = y;

y = tempp;

printf("Value of x = %f\n",x);

printf("Value of y = %f\n",y);

printf("Arithmetic = %f\n",(x + 12/y -18));

char grade = 'A';

int a,b,c,d;

a = 5; b = 2; c = 3; d = 6;

int x = round(z);

Explanation:

The answers are straight forward.

However, I'll give a general hint in answering questions like this.

In C, variable declaration is done by:

data-type variable-name;

To declare and initialise the variable, you do;

data-type variable-name = value;

So, for questions that requires that we declare and initialise a variable, we make use of the above syntax..

Take (a) for instance:

int x = 25;

int y = 18;

Same syntax can be applied to (b), (d), (e), (h) & (I)

For question (c);

This can be done in two ways;

x = x + 5;

x+=5;

Both will give the same result.

For question (f):

We start by initialise a temporary variable that stores x.

Then we store the value of x in y.

Then we store the content of the temporary variable to y.

This swaps the values of x and y

For question (g):

When printing a double variable in C, we make use of '\f' as a string format

For question (j):

The round function is used to round up a double variable to integer.

Write statements that output variable numComputers as follows. End with a newline

gavmur [86]

Complete Question:

Write statements that output variable numComputers as follows. End with a newline. There are 10 computers.

#include <iostream>

using namespace std;

int main()

{

int numComputers;

cin >> numComputers; // Program will be tested with values: 10.

...

return 0;

}

Answer:

cout << "There are ";

cout << numComputers;

cout << " computers." << "\n";

Explanation:

Using three cout statements the string "There are 10 computers." is printed out, notice that the variable numComputers is entered by the user when the program is run. Another way of concatenating an integer variable and string for printout is by the use of the + (plus) operator.
