Question

int temp = 0x5E; // in binary 0b1011110. 

Is there such a way to check if bit 3 in temp is 1 or 0 without bit shifting and masking.

Just want to know if there is some built in function for this, or am I forced to write one myself.

Answer 1

In C, if you want to hide bit manipulation, you can write a macro:

#define CHECK_BIT(var,pos) ((var) & (1<<(pos))) 

and use it this way to check the n^th bit from the right end:

CHECK_BIT(temp, n - 1) 

In C++, you can use std::bitset.
