Question

How much memory is set aside by the following commands? Show your work.
int nums[4];
double vals[5];

Answer 1

As an int variable takes 2 bytes, then an array of 4 ints will take 8 bytes. So,

int nums[4];

sets 16 bytes of memory. Analogically, double variable usually takes 4 bytes, therefore

double vals[5];

sets 20 bytes.
