What does kapow() return in this C program?
#include <stdint.h>
uint32_t howjadoo(uint32_t prevsum, uint16_t command, uint16_t response)
{
return prevsum + (command - response);
}
uint32_t kapow()
{
return howjadoo(100000, 10001, 10002);
}

Interesting quiz! One quick correction to the explanation section, which says "On machines where an int is 8 or 16 bits,...". The int type in C cannot be only 8-bit wide even on 8-bit CPU. This is because the C Standard says that "Basic signed integer type. Capable of containing at least the [−32,767, +32,767] range."
Good point I didn't know about
Well, I could understand the result if the quiz was written using "int", "unsigned int", "long" and "unsigned long" which are processor dipendent but every I looked it says that uint16_t is 2 bytes and uint32_t is 4 bytes regardless the processor. I am confused.
