Correct Answer: Adapter and observer pattern
Correct Answer: none of these
Explanation:
There are two types of modular programming.They are interface and implementation.
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: 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
Correct Answer: Fact is key performance indicator to analyze the businessFrom the additive values, which are used to analyse the business by using report generation Dimension is used to analyze the fact, are the non-additive ( text format) values, Which are used to drill down reportsWithout dimension there is no meaning for fact Measure is the quantity of data we create to process
Correct Answer: - When u build connection with database through coding, then its ADODBWhen u build connection with database through ADO component, then its ADODC - ADODB is a ActiveXdll and ADODC is a ActiveXcontrol - No Need to bind with controls in ADODB whereas in ADODC we should bind with controls
