Default size of a pointer in SoloLearn Challenges

If is not specified in a challenge, I could assume its 4 bytes?

4 bytes in 32 bits. 8 bytes in 64 bits.

it also depends if it is a function pointer. function pointers can be more than 8 or 4 bytes which is why they may not be converted to or from void pointers. i think in C we cannot safely assume the sizes of anything but a char, but what CarrieForle said is usually true most of the time.

Martin Taylor The size of a char is guaranteed to be 1 byte by any ISO standard compiler (not necessarily 8 bits). multibyte/wide char and char are different and treated differently.
