Given a 32-bit register, bits 11:8 are PART_NUM and bits 7:0 are PART_REV. Output a 32bit value in the following format: [0000][0000][0000][0000][0000][0000][PART_FAM][PART_NUM] What is the minimum number of lines to write this function?
most question were based on C and OS related question. volatile, static, Linked list, stack, queues, context switching, Strings,
c++ questions
