C Program to check whether ith bit in a number N is set or not

WebC-style bit-manipulation. The value of the bit can be obtained by shifting the number to the right x times and then performing bitwise AND ( &amp;) on it: (number &gt;&gt; x) &amp; 1LL; // 1 if the 'x'th bit of 'number' is set, 0 otherwise. The right-shift operation may be implemented as either an arithmetic (signed) shift or a logical (unsigned) shift. WebReturn bit value Returns whether the bit at position pos is set (i.e., whether it is one ). Unlike the access operator ( operator [] ), this function performs a range check on pos before retrieveing the bit value, throwing out_of_range if pos is equal or greater than the bitset size. Parameters pos
