MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -A constant is a value that cannot be altered by the program during normal execution, i.e., the value is constant. When associated with an identifier, a constant is said to be “named, ” although the terms “constant” and “named constant” are often used interchangeably.

Detailed explanation-2: -Constant is an entity that refers to a fixed value of data and which cannot be modified. During execution/computation of programming, the value of a constant cannot be altered, it remains constant.

Detailed explanation-3: -Detailed Solution Constant is an object whose value cannot be changed once defined for the design so option( 2) is not true.

Detailed explanation-4: -A constant is an identifier (name) for a simple value. The value cannot be changed during the script. A valid constant name starts with a letter or underscore (no $ sign before the constant name).

Detailed explanation-5: -A constant is a named piece of memory where the value cannot be changed while a program runs. Constants are useful because they are declared and assigned once, but can be referred to over and over again throughout the program.
