Important pitfalls
Value of the variable stored in register of cpu not for memory

Answer / arka bandyopadhyay

1-As the value of the register variable is to be stored under the processor register which is limited and if processor is of 16 bit we cannot store float values and higher data type values as 2pow(4bytes)=16bits which a 16 bit processor's registor cannot store hence the variable will now act as an automatic variable


2-Register might be busy in some other operation then also register might not be accessible and hence will act as an automatic variable

Answer / kiran

As the no. of registers in a CPU are limited,we cannot declare many variables as register
