The provided code generates a random integer between 1 and 3 (inclusive). Here's a breakdown of what each part does:
int numeroRandom = 1 + (rand() % 3);
-
rand()
: This function generates a pseudo-random integer, typically between0
andRAND_MAX
(a predefined constant that depends on the system, defined in<stdlib.h>
). -
rand() % 3
: The modulus operator (%
) restricts the output ofrand()
to a range of values from0
to2
. This is because takingrand() % 3
will give you the remainder when dividingrand()
by 3, which is always in the range0, 1, 2
. -
1 + ...
: Adding1
shifts the range from0-2
to1-3
. This ensures the output is in the inclusive range[1, 3]
.
Final Behavior
The code assigns a random integer between 1 and 3 (inclusive) to the variable numeroRandom
. Note that the randomness of rand()
depends on whether srand()
has been used to seed the random generator beforehand. If srand()
is not called, you might get the same sequence of values each time the program runs.
