Number 2 is the correct answer
The keywords used in programming languages that use decisions to redirect the flow of a program are called control structures.
Answer:
The answers to 1st question and part 2A is given. However, the 2B is not given complete and thus cannot be answered.
Explanation:
UNION is a keyword used in C Language to have a commonly shared memory that can be used by multiple elements. It is a data-type that allows different data types to use the same shared memory location.
Importance: If you want to minimize the use of memory by sharing it between different datatype variables, then use UNION. For Ex. Let's suppose I want to use 2 variables a and b of type char and int respectively. Now, suppose int takes memory space of 2 bytes and char takes 1 byte then the total amount of memory needed = 2 + 1 = 3 Bytes. But, we want to first make use of a, and once done, we want to declare variable b. We can limit the memory use by declaring a memory space of 2 bytes (max of a and b). First, we can use this space to store the int variable and when done with it, we can use it to store the char variable.
PART 2A
typedef struct{
int partNum;
char partName[25];
} partin;
#define Partin partin
Because most people really don't want or need to see what's in there.
If you want to, open the door during the cycle. It won't harm anything.
If you're curious to see a dishwasher in action, some appliance showrooms have a display model, where the spray parts and the racks are in an entirely transparent box. They're to show how powerfully and completely the stuff inside will get cleaned, but you can also see how the dishwasher is intended to work, by filling with just a couple of inches of water, and then recirculating it for the duration of the cycle, to loosen the stuff on the dishes.
