What is the difference between call by value and call by name in programming languages?
In call by value, the value of the argument is passed to the function, while in call by name, the expression for the argument is passed and evaluated each time it is used in the function.
Why is a string immutable in programming languages?
A string is immutable in programming languages because once it is created, its value cannot be changed. This helps ensure data integrity and prevents accidental modifications that could lead to errors in the program.
What is the difference between a procedure and a function in programming?
In programming, a procedure is a set of instructions that performs a specific task, while a function is a type of procedure that returns a value. Functions are more versatile and reusable because they can be called multiple times and can return a result. Procedures, on the other hand, are used for tasks that do not require a return value.
What is the difference between the values of "a" and "a"?
The difference between the values of "a" and "a" is that "a" is higher in value and indicates a better performance or achievement compared to just "a."
What is maximum limit of no in computer?
Most modern programming languages provide several fixed length values, as these can be easily and efficiently used by modern processors. They are usually 32 and 64 bit integer values, which have maximum values of 4,294,967,296 and 18,446,744,073,709,551,616, respectively. Many modern languages also implement the IEEE-754 floating point format, which allows for a maximum value of about 1.798*10308. Of course, there are a lot of languages which also allow for arbitrarily-large values, which are limited only by RAM.
