Question

The statement:

int grades[ ] = { 100, 90, 99, 80};

shows an example of:

A) default arguments
B) an illegal array declaration
C) an illegal array initialization
D) implicit array sizing
E) None of these

Answer 1

The statement provided is an example of implicit array sizing, where the compiler determines the size of the array based on the number of elements in the initialization list.

Step-by-step explanation:

The statement int grades[] = { 100, 90, 99, 80}; is an example of D) implicit array sizing. In this context, the array grades is being initialized with four values, but the size of the array is not explicitly stated. Instead, the size of the array is implied by the number of elements provided in the curly braces. This is a legal and common practice in C/C++ programming when initializing arrays. Hence, the correct option out of the ones provided is implicit array sizing.
