I need to store a value between 0-15 in C , 4 bits are enough for this. How can I just have a variable of 4 bits? Space is a constraint here

Consider using a
char. Yeah, it’s 8-bits, but you can use the bit shift operators (<<and>>) to store values in the other 4 bits.Edit: Per the comments below, an
unsigned charis, in fact, preferable overcharto avoid issues with the sign bit.
