a.) Lets assume that a processor has carry, overflow, negative and zero flags and it performs addition of the following two signed number -63 and +63 with 8 bits representation. After the execution of this addition operation, the status of the carry, overflow, negative and zero flags, respectively will be: b.) Lets assume that a processor has carry, overflow, negative and zero flags and it performs addition of the following two unsigned number 156 and 114 with 8 bits representation. After the execution of this addition operation, the status of the carry, overflow, negative and zero flags, respectively will be: c.) Lets assume that a processor has carry, overflow, negative and zero flags and it performs addition of the following two signed number -63 and -117 with 8 bits representation. After the execution of this addition operation, the status of the carry, overflow, negative and zero flags, respectively will be:
