Counting Memory

We tend to count memory using hexadecimal rather than binary.

• Uses the 0x prefix.
• e.g., 0x10 is just 10, the hexadecimal representation of 16

Example: Storing an Int

#include <stdio.h>
int main(void)
{
    int n = 50;
    printf("%i\n", n);
}

1. An int typically takes 4 bytes
2. The number 50 has an address for where it is in memory, like 0x123
