saul85 [17]

Answer:

a.

int x = 25;

int y = 18;

b.

int temp = 10;

char ch ='a';

c.

x += 5;

d.

double payRate = 12.5;

e.

int tempNum = firstNum;

f.

int tempp = x;

x = y;

y = tempp;

g.

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

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

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

h.

char grade = 'A';

i.

int a,b,c,d;

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

j.

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;

Or

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.

Difference and similarity between cluster computing and Hadoop ecosystem?<br>​
Marysya12 [62]
  • Some things can be similar and still have some differences. The Hadoop ecosystem is known to be the add-ons that make the Hadoop framework more better for some particular big data needs and tastes.

The Hadoop ecosystem is made up of the open source projects and commercial tools that are often optimized to act on different kinds of work especially to big data. It is very flexible

The differences is that cluster is simply a combination of a lot of computers that is set up to work together as one system but a Hadoop cluster is a cluster of computers that is used only at Hadoop. Hadoop clusters are set up to analyze and storing large amounts of unstructured data only in a distributed file systems.
