Question

What will this print?

int x=10;cout << sizeof(x);

a. 4
b. 8
c. 2
d. 10

Answer 1

The code will print the number of bytes that an integer occupies in memory, which is typically 4 bytes on modern systems.

Step-by-step explanation:

When the code int x=10; cout << sizeof(x); is executed, it prints the size of the variable x in bytes. The size is determined by the data type of x, which in this case is int. On most modern systems, the size of an int is 4 bytes. Therefore, the correct answer is a. 4.
