Answer:

You should do this:

if (0==strcmp(modelName,"Extravagant") && modelYear >= 1999 && modelYear <= 2002)

printf("%s\n","RECALL");

Explanation:

Lets consider this program and analyze the output.

int main()

{

int modelYear;

char modelName[30];

printf("enter the year");

scanf("%d",&modelYear);

printf("enter the modelname");

scanf("%s",modelName);

if (0==strcmp(modelName,"Extravagant") && modelYear >= 1999 && modelYear <= 2002)

printf("%s\n","RECALL"); }

if (0==strcmp(modelName,"Extravagant") && modelYear >= 1999 && modelYear <= 2002)

This statement has a function strcmp which is used to compare two strings.

If the user enters Extravagant as model name then this input will be compared by the string stored in modelName i.e. Extravagant, character by character. If the string entered by the user matches the string stored in modelName this means this part of the if condition evaluates to true. 0==strcmp means that both the strings should be equal.

The next part of the if statement checks if the model year entered is greater than or equal to 1999 AND less than or equal to 2002. This means that the model year should be between 1999 and 2002 (inclusive).

&& is the logical operator between both the parts of if statement which means that both should evaluate to true in order to display RECALL.

This is correct way to use because the if (modelName == "Extravagant" && modelYear >= 1999 && modelYear <= 2002) printf("%s\n","RECALL"); statement will not display RECALL. After entering the model name and model year it will move to the next line and exit.

So in if (0==strcmp(modelName,"Extravagant") && modelYear >= 1999 && modelYear <= 2002)

printf("%s\n","RECALL"); statement when the if condition evaluates to true, then RECALL is displayed in the output.

ReFS format and Storage Spaces.

Explanation:

ReFS(Resilient File System)format was introduced in 2012 and it was the replacement for NTFS(NT File System).It was introduced as a part of the Windows Server.ReFS supports maximum value of 1 yottabyte (1 one million Terabytes). It also supports auto-correct form disk errors and data corruption.You need a storage space to store the data hence we need storage space also.

Suppose that instead of swapping element A[i] with a random element from the subarray A[i..n], we swapped it with a random eleme

Answer:

The answer to this question can be defined as follows:

Explanation:

Its Permute-with-all method, which doesn't result in a consistent randomized permutation. It takes into account this same permutation, which occurs while n=3. There's many 3 of each other, when the random calls, with each one of three different values returned and so, the value is= 27. Allow-with-all trying to call possible outcomes as of 3! = 6

Permutations, when a random initial permutation has been made, there will now be any possible combination 1/6 times, that is an integer number m times, where each permutation will have to occur m/27= 1/6. this condition is not fulfilled by the Integer m.

Yes, if you've got the permutation of < 1,2,3 > as well as how to find out design, in which often get the following with permute-with-all chances, which can be defined as follows:

$\bold{PERMUTATION \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ PROBABILITY}$

$\bold{ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 4/27= 0.14 }\\\bold{ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 5/27=0.18}\\$

$\bold{ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 5/27=0.18}\\\bold{\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 5/27=0.18}$

$\bold{ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 4/27=0.14}$

Although these ADD to 1 none are equal to 1/6.
