Question

Any problems with this code?

int a[10];
cout << () << '\\';
A) No, it will print the content of array `a`
B) Yes, it will result in a compilation error
C) Yes, it will print garbage values
D) No, it will print the size of array `a`

Answer 1

The given code will result in a compilation error since the cout statement has empty parentheses and no content to print. To print the array's content or size, specific syntax must be used.

Step-by-step explanation:

The code provided has an issue which will result in a compilation error. The cout statement is attempting to print something, but the parentheses are empty. To fix this code and to print something meaningful, you would need to put an expression or a variable inside the parentheses.

If the intention was to print the content of the array a, you would need a loop to print each element individually, as cout does not support printing the entire array directly. If the intention was to print the size of the array a, you would use sizeof(a)/sizeof(a[0]), providing that a is a statically allocated array and not a pointer to an array.

So, the correct answer to the question is: B) Yes, it will result in a compilation error.
