A. Size of a data type in bits B. Size of a data type in bytes C. Size of a variable in bytes D. Size of a variable in bits

A. Char B. Float C. String D. Double

A. To declare a variable with dynamic storage duration B. To declare a constant C. To declare a variable with external linkage D. To declare a variable with static storage duration

A. None of the above B. They both have the same effect C. '++i' increments the value of 'i' before returning it, while 'i++' increments the value of 'i' after returning it D. '++i' increments the value of 'i' after returning it, while 'i++' increments the value of 'i' before returning it
