Question

Which of the following function declarations correctly expect an array as the first argument?

Question 1 options:

void f1(int array, int size);

void f1(int& array, int size);

void f1(int array[100], int size);

void f1(float array[], int size);

All of the above

C and D

A and B

Answer 1

Only

Option: void f1(float array[], int size);

is valid.

Step-by-step explanation:

To pass an array as argument in a function, the syntax should be as follows:

functionName (type arrayName[ ] )

We can't place the size of the array inside the array bracket (arrayName[100]) as this will give a syntax error. The empty bracket [] is required to tell the program that the value that passed as the argument is an array and differentiate it from other type of value.
