Answer:

c. StringBuilder

Explanation:

An alternative to the String class would be the StringBuilder Class. This class uses Strings as objects and allows you to mix and match different strings as well as adding, removing, implementing, and modifying strings themselves as though they were similar to an array. Unlike the string class StringBuilder allows you to modify and work with a combination of strings in the same piece of data as opposed to having various objects and copying pieces which would take up more memory.

Andrej [43]

Answer:

It is good to know about the differences between margin and padding .Margin is the outer space of an element, while padding is the inner space of an element. In other words, margin is the space outside of an element's border, while padding is the space inside of its border. You can set auto value to margin.

What is the decimal equivalent of 11BA?

allsm [11]

Answer:

To convert hexadecimal number 11BA to decimal, follow these two steps:

Start from one's place in 11BA : multiply ones place with 16^0, tens place with 16^1, hundreds place with 16^2 and so on from right to left

Add all the product we got from step 1 to get the decimal equivalent of 11BA.

Using the above steps, here is the work involved in the solution for converting 11BA to decimal number (Don't forget that we start from ones place to so on...)

Decimal equivalent of "A" = (A) 10 × 16^0 = 10

Decimal equivalent of "B" = (B) 11 × 16^1 = 176

Decimal equivalent of "1" = 1 × 16^2 = 256

Decimal equivalent of "1" = 1 × 16^3 = 4096

Decimal equivalent of "11BA" = 409625617610

11BA = 4538

Here is the final answer, The hexadecimal number 11BA converted to decimal is therefore equal to:

4538

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.
