What is meant by the term case-sensitive in Java?
Java is a case-sensitive language, which means that the upper or lower case of letters in your Java programs matter.
What does a variable declaration tell the Java compiler about a variable?
What does a variable declaration tell the Java compiler about a variable? A variable tells the Java compiler the variable’s name and the type of data it will hold. That the particular value will hold certain amount of memory to store values.
Is Java programming language case-sensitive explain and give an example?
Java, like most programming languages, is case sensitive. Even the slightest difference in naming indicates different objects (count does not equal Count). In order to be consistent, programmers follow naming conventions. For example, variables are lowercase (car) and classes are uppercase (Car).
Why is it good advice to indent all the statements inside a set of braces?
Why is it good advice to indent all the statements inside a set of braces? By indenting the conditionally executed statements, you are causing them to stand out visually. This is so you can tell at a glance what part of the program the if statement executes.
Why is it important to declare a variable?
Declaring Variables
Before they are used, all variables have to be declared. Declaring a variable means defining its type, and optionally, setting an initial value (initializing the variable). … Variables will roll over when the value stored exceeds the space assigned to store it.
Why do we need to declare variables?
A declaration is used to announce the existence of the entity to the compiler; this is important in those strongly typed languages that require functions, variables, and constants, and their types to be specified with a declaration before use, and is used in forward declaration.
Is a boolean variable that signals when some condition exists in the program?
A Flag is a boolean variable that signals when some condition exists in a program. When a flag is set to true, it means some condition exists When a flag is set to false, it means some condition does not exist.
What risk does a programmer take when not placing a trailing else?
What risk does a programmer take when not placing a trailing else at the end of an if-else-if statement? There is a chance that the program will not compile because Java is looking for other factors that may be possible. No code executed.
Which variable controls number of iterations performed by a loop?
Indentation is used to show which steps are to be iterated. In this example, the variable ‘count‘ is used to keep track of how many times the algorithm has iterated. This variable controls the loop. The algorithm will continue to iterate until the value of count has reached 5.
Why are Boolean variables commonly used as flags?
Boolean values are regularly used to help maintain the state of a given piece of code. It is common to describe boolean variables as “boolean flags” – these often are used to turn on and off different behaviors that might be useful.
What is meant by conditionally executed?
Explane what is meant by the term conditionally executed. A conditionally executed statement is performed only when a certain condition is true. 2. You need to test a condition and then execute one set of statements if the condition is true. If the condition is false, you need to execute a different set of statements.
What is not part of a variable declaration in the C# programming language?
What is NOT part of a variable declaration in the C# programming language? The variable’s associated parent class.
Why do we use flags in C programming?
Flag variable is used as a signal in programming to let the program know that a certain condition has met. It usually acts as a boolean variable indicating a condition to be either true or false.
What are Boolean variables commonly used as?
Concept: A Boolean variable can reference one of two values: True or False. Boolean variables are commonly used as flags, which indicate whether a specific condition exists.
What is difference between Boolean and flag?
Returning a bool locks you in now, whereas using flags allows you greater flexibility in the future. So what if you never need more than two values in the future.
What is flag in C programming?
A “flag” variable is simply a boolean variable whose contents is “true” or “false”. You can use either the bool type with true or false , or an integer variable with zero for “false” and non-zero for “true”.
What is a flag and what are its uses?
What Does Flag Mean? A flag is one or more data bits used to store binary values as specific program structure indicators. … A computer interprets a flag value in relative terms or based on the data structure presented during processing, and uses the flag to mark a specific data structure.
Which flag is not used in programming?
