Correct Method Declaration in Programming

Which of the following method declarations is correct?

A. 'int show()' 'int show{ return 1; }'

B. 'show() { }' 'int show() { return 1;'

C. 'int show（）｛ return 1;｝'

The correct answer is C. 'int show（）｛ return 1;｝'.

This option correctly demonstrates the typical syntax for a method declaration, including:

• Data type: 'int' specifies the return type of the method.
• Method name: 'show' is the identifier for the method.
• Parentheses: '（）' enclose the method's parameters, which are empty in this case.
• Braces: '｛｝' enclose the method's body, containing the code to be executed.

Let's break down why the other options are incorrect:

• A. The syntax is invalid. The method definition should use parentheses '()' for parameters, not curly braces '{}'.
• B. The method declaration lacks a return type declaration. While it defines a method body, the lack of a return type makes it incomplete.
• C. This is the correct and complete method declaration.
