Question

Which of the following function prototypes are not valid?

A) void do Something(int x, int y);
B) void do Something(int* x, int* y);
c) void do Something(int* x, int y);
D) All are not valid.
E) All are valid

Answer 1

All three function prototypes A) void doSomething(int x, int y); B) void doSomething(int* x, int* y); and C) void doSomething(int* x, int y); are valid in programming languages like C and C++. Therefore, the correct option in the final answer is E) All are valid.

Step-by-step explanation:

The question is asking which of the given function prototypes are not valid in the context of programming. In most programming languages like C and C++, a valid function prototype specifies the return type of the function, the name of the function, and the types of its parameters within parentheses. All three function prototypes listed in the question are valid and commonly used patterns in C or C++:

• A) void doSomething(int x, int y); - This is a function that takes two integers as arguments and does not return a value.
• B) void doSomething(int* x, int* y); - This is a function that takes two pointers to integers as arguments and does not return a value.
• C) void doSomething(int* x, int y); - This is a function that takes a pointer to an integer and an integer as arguments and does not return a value.

Based on the information provided, we can conclude that option E) All are valid is the correct option in the final answer.
