The correct answer to the given question is:

B) int funct(int x) { return x=x+1; }

Explanation:

Functions "Encapsulate" a task (they combine multiple commands into a single line of code). Most programming languages ​​provide many built-in functions that would otherwise take many steps to complete, such as calculating the square root of a number. In general, we don't care how a function does what it does, only how it "does" it!

When a function is "called", the program "leaves" the current code and starts executing the first line inside the function.

Steps to write a function

• Understand the purpose of the function.
• Determine the data that goes into the function from the caller (as a parameter)!
• Define the data variables needed inside the function to achieve its purpose.
• Decide on the set of steps the program will use to achieve this goal. (Algorithm)
