Which of the following function declarations correctly accepts a pointer to an integer as an argument?Marks : 1Negative Marks : 0Answer herevoid func(int &x);void func(int *x);void func(int x);void func(int &*x);
Solution
The correct function declaration that accepts a pointer to an integer as an argument is:
void func(int *x);
This is because in C++, the asterisk (*) is used to denote a pointer. So, "int *x" means "x is a pointer to an integer". The other declarations are either for passing by value (void func(int x);) or passing by reference (void func(int &x);), which are different from passing a pointer. The last declaration (void func(int &*x);) is invalid in C++.
