Answer: A) systems analysis phase of the SDLC.
Explanation:
In accordance with system development life cycle(SDLC) , analysis phase is the stage where all the requirement and materials for the system are collected and ordered.The requirements are in the form of input and output which are extracted and documented to provide clear vision of outcome.
- Other options are incorrect because design phase is for designing the format ans structure of system through input components. Planning and selection stage is making scheme through opting correct requirement for system.
- Implementation and operation phase is the stage of implementing the components on system structure to make them perform their respective tasks. Logic modelling level is defining inputs , components, outputs in logical manner so that they provide desired result operating.
- Thus, the correct operation is option(A).
Answer:
The main difference between creating a table in word and excel is that there are more number of table tool and the layout section in the excel as compared to the MS word.
Creating a table in word or excel are only depend on the requirements of the particular table. If there is less number of calculations in the table then, it is easy to create the table in word as compared to excel.
And if we want to create a table with maximum numbers of rows and column and also contain high math calculation then, it is good to create in excel.

Subject: To apply for an internship in your esteemed XYZ Software development company
Respected Sir,
I am in the final year of my engineering, and my specialization is Information technology.
Being an IT student, I am quite good at organizing as well as filing the office materials. I have expertise by now in project management as well, and I can prepare any form of software project documents, project schedules, or any form of software project management reports. I am proficient in communication as well and write as well as send any type of email. I can perform any kind of communications task. I can participate as well as take note of any kind of team meetings as well as observe and capture details of the interaction with any sort of client with the same intent. I am at first an IT Expert and hence can enter any length of data into any software on computer systems. Also, I can work quite effectively on any operating system, and on both Mac OS and Windows PC. I also have the required know-how of computer hardware just in case it is required. I have a very deep interest in technology, and can quite effectively use the word processing programs, and do an extensive research on any topic or any sort of search and findings on internet.
Kindly please grant me an opportunity to work as an intern in your esteemed company.
Yours amicably,

Explanation:
The Answer is self explanatory.
Here are the basics of C++...
Number 1. Printing text onto the screen:
std::cout << "Your text here\n";
The \n creates a new line.
Number 2. Initializing variables and setting variables
There are a few different types of variables in C++...
Integers, floats, chars, and strings.
To let C++ know what type of variable you are about to create, you put the type before the variable name.
Here are some examples:
int number = 10;
float r = 2.45;
char[4] = "Code";
string name = "Bob";
Number 3. Comments
In programming comments are very useful. They help other programmers understand your code.
To make a single line comment in C++ you do this:
// your comment
To make a multi-line comment in C++ you do this:
/*
My multi-line comment here
*/
Number 4. Math
In C++ you have math operators. These operators are + - * / %
I'm pretty sure you are familiar with the first four operators. But you may not know the last one. Don't worry... I'll explain that one to you.
Addition:
std::cout << 35 + 23 // this will print out 58
Subtraction:
std::cout << 102 - 56; // this will come out as 46
Multiplication:
std::cout << 34 * 9; // product will be 306
Division:
std::cout << 164 / 4; // quotient will be 41
Modulus:
Now we get to the operator you may or may not know. The modulus.
The modulus operator gets the remainder of division of a by b.
std::cout << 10 % 4; // it will print out 2
You can even store math operations in variables...
int answer = 40 + 38;
std::cout << answer; // this will print out 78
You can even add variables...
int x = 28;
int y = 58;
int answer = 86;
std::cout << answer;
std::cout << x + y;
Number 5. Comparison Operators.
Comparison operators compare two values to see if its true or false...
These are mainly used in if statements...
Here are the comparison operators:
== Equal
!= Not equal
> Greater than
< Less than
<= Less or equal
>= Greater or equal
Number 6. If Statements
This is the structure of an if statement:
if(...){
// execute code if true
} else if(...){
// execute this block of code if first if statement was false
}else {
// execute this block of code if false
}
if(2 > 1) {
std::cout << "2 is greater than 1";
}
The code above will indeed execute. Because two is greater than 1.
Number 7. Functions
If you have a block of code that will be repeated multiple times through out your program, functions will be handy.
To make a function you must specify the type of the function. This called the return type.
Which are int (integers), floats (decimals), and string (strings).
There are more, but I decided to focus on those three.
Then you give your function a name.
int my_function(){
// your code
}
To call a function, you simply type the name of the function with parentheses.
my_function();
To make a function with parameters, do same thing above, except in the parentheses you give your parameters.
int my_function(int x, int y){
// your code
}
As you can see, you separate the parameters with a comma.
in my_function(int x, int y){
int z = x + y;
std::cout << z; // this will print out the sum of x and y
}
To call your function with parameters, type your function name with parentheses and in the parentheses type your values.
my_function(3, 4); // this will print out 7
Also, another type of function is the void type. In int type functions, at the end of your code in the function, you should type return 0.
This allows C++ know that code wen't without any errors...
In void type function this isn't really necessary...
If you have anymore questions or you found something to be confusing or you want to learn more C++, please write me a message.
Answer:
The specification is defined downwards according to the conclusions reached.
Explanation:
Real-world instances or examples of issues that do not scale well are listed following table:
- For different uses, such as solving the equation, respectively., multiplication matrices.
- It still does not scales or works well to organize a wide sequence of names or numbers as the requisite measures raise as squares by around the enlargement or increment.
