Which statement is used to create a variable or constant in programming?

The declaration statement is fundamental in programming as it serves the specific purpose of defining a variable or constant. When you declare a variable, you essentially inform the compiler or interpreter about its name, type, and initial characteristics. This allows the program to allocate the necessary memory space and prepare to handle the variable as intended.

For instance, in many programming languages, a declaration can look something like this:

int count;  // Declaration of a variable named count of type integer

This line tells the system to create a variable count that can hold integer values. Similarly, constants can also be declared, often using a keyword that specifies that the value cannot change throughout the program’s execution.

Other types of statements in programming serve different purposes. The assignment statement is used to assign a value to a previously declared variable. Conditional statements control the flow of execution based on specific conditions, while loop statements are used for repeating a block of code multiple times. Each of these has a unique role, but none are used for the initial creation of a variable or constant.
