Right shifting of a data (number) by 1 is equivalent to data/2. In data, every bit is a power of 2, with each right shift we are reducing the value of each bit by a factor of 2. #include . int main() {. unsigned int data = 16; data = data >> 1;
WebBit Fields in C In C language, we have union and struct data types where we can declare user-defined data types. The size of the struct depends on data members. But sometimes, we do not need such a huge size of the data type, because it occupies memory, and it creates a waste of memory. Example 1: #include struct dob { int date;
