Which of the following is true about return type of functions in C?a)F...
Explanation:
In C, functions can return any type except array and functions. This means that a function can return a value of any data type such as int, float, char, double, struct, etc. However, it cannot return an array or another function.
Why functions cannot return arrays or functions?
The reason why functions cannot return arrays or functions is that C does not allow passing an array as a function argument. Instead, an array is automatically converted into a pointer to its first element. Therefore, if a function returns an array, it would actually be returning a pointer to the first element of the array. Similarly, if a function returns a function, it would actually be returning a pointer to that function.
Why functions cannot return union?
A union is a special data type in C that allows storing different data types in the same memory location. However, since the size of a union is determined by its largest member, it can be difficult to determine the size of the union at compile-time. Therefore, C does not allow returning a union from a function.
Why functions cannot return function pointer?
A function pointer is a variable that stores the address of a function. Since a function pointer can be of any function type, it can be difficult to determine its size at compile-time. Therefore, C does not allow returning a function pointer from a function.
Therefore, the correct answer is option 'B' - Functions can return any type except array and functions.

In C, functions can return any type except arrays and functions. We can get around this limitation by returning pointer to array or pointer to function.
