Correct Answer: struct a_struct {int a;};
Explanation:
The a_struct is declared as structure name and its data element is a.
Correct Answer: Both A & B
Explanation:
Hypertext Markup Language (HTML) is the standard markup language for creating web pages and web applications.
HTML tags are the hidden keywords within a web page that define how your web browser must format and display the content. Most tags must have two parts, an opening and a closing part. For example, <html> is the opening tag and </html> is the closing tag.
Correct Answer: 1
Explanation:
Use HTML tag <ol> element to define an ordered list.
Use the HTML type attribute to define the numbering type. Use the HTML <li> element to define a list item. Use the HTML <dl> element to define a description list.
Hence, as numbered list come under ordered list tag <ol> tag is used for numbered list.
Correct Answer: - In order to create a DHTML drop down menu we need JavaScript API The API (Application Programming Interface) consists of core set of cross-browser JavaScript functions to make DHTML programming easy and quick This API enables moving and hiding page elements as well as acts as getter and setter of page elements attributes - Second we define on image object and off image object and string containing the URL of the "off" version - Then we create the menu items, label items and sub-menu items If we wish we can use images also - Then we need to define our own global variables that will be used by the menu Using global goes against oops design but makes sharing data easier - Create the menubar object, adding the menu labels and writing menubars - Create menu object, adding menu items and writing menus - Hiding and displaying the menus and attaching stylesheet
Correct Answer: Call Screen: Calling a single screen is a special case of embedding a screen sequence If you want to prevent the called screen from covering the current screen completely, you can use the CALL SCREEN statement with the STARTING AT and ENDING AT CALL SCREEN 1000 CALL SCREEN 1000 STARTING AT 10 10 ENDING AT 20 20 LEAVE SCREEN statement ends the current screen and calls the subsequent screen LEAVE SCREEN LEAVE TO SCREEN 2000
Correct Answer: Adapter and observer pattern
Correct Answer: (double) amount
Correct Answer: Most of the times compilers will do optimization to the code to speed up the program For example in the below code, int k = 15; while( k == 15) { // Do something } compiler may think that value of 'k' is not getting changed in the program and replace it with 'while(true)', which will result in an infinite loop In actual scenario, the value of 'k' may be getting updated from outside of the program Volatile keyword is used to tell compiler that the variable declared using 'volatile' may be used from outside the current scope, so that compiler won't apply any optimization This matters only in case of multi-threaded applications In the above example if variable 'k' was declared using volatile, compiler will not optimize it In shot, value of the volatile variables will be read from the memory location directly
Correct Answer: real
Explanation:
A variable provides us with named storage that our programs can manipulate. Each variable in C++ has a specific type, which determines the size and layout of the variable's memory the range of values that can be stored within that memory and the set of operations that can be applied to the variable.
The name of a variable can be composed of letters, digits, and the underscore character. It must begin with either a letter or an underscore. Upper and lowercase letters are distinct because C++ is case-sensitive ?
Basic types of variables:
1. bool
Stores either value true or false.
2. char
Typically a single octet (one byte). This is an integer type.
3. int
The most natural size of an integer for the machine.
4. float
A single-precision floating point value.
5. double
A double-precision floating point value.
6. void
Represents the absence of type.
7. wchar_t
A wide character type.
Correct Answer: Generally a business analyst covers several stages in Software Development Life Cycle Like: Client Consulting, Client Requirement Study, Planning for business needs, Business Requirement Documenting, Work on functional requirement, Prepare test data with inputs from end users, Document use case scenarios, Help Testing team with test plan and testing, Help end users with user acceptance testing UAT, Go live and post production support tasks
