UGH IKR, LIKE JUST ANSWER THE FRICKIN QUESTION
A CPU is the electronic circuitry within a computer that carries out the instructions of a computer program by performing basic arithmetic logical, control and input/output operations specified by the instructions.
Knowing this, the answer is both C - That it coordinates the flow of instructions and data within computers, And A - That a control unit performs arithmetical and logical computations.
If you can only select one answer, I'd personally go with A.
Answer:
Read-only memory, or ROM, is a form of data storage in computers and other electronic devices that can not be easily altered or reprogrammed. RAM is referred to as volatile memory and is lost when the power is turned off whereas ROM in non-volatile and the contents are retained even after the power is switched off.
Answer:
MYSTRUCT myStruct[8]; // statemnt to create an array of struct variables
myStruct[3].buf[4] // statement to access the fourth element of the array of the struct variables.
struct * MYSPTR = &myStruct; // This statement creates a pointer.
To dereference and access the S variable of the struct data structure in the array;
(*MYSPTR).S and its shorthand notation MYSPTR -> S
Explanation:
A structure is a data structure in C language that is used to hold descriptive data of an object. The keyword struct is used to create the structure. An array of struct holds instances of a struct variable, where each struct can be accessed using the regular array indexing and the variables of the structs in the array can be accessed using dot notation.
