Given an array a, write an expression that refers to the first element of the array .

one business rule is that each project has one manager. Identify two (and no more than two) problems with the data structure or

Vinil7 [7]

Answer:

1. The data will not be tallying up - there will great variations and deviance.

2. There will be not enough data points

Explanation:

The management style, though it uses one manager, is not devoid of problems in the system. For example, there will be great difficulty in the collection of accurate data to properly define the system. This presents a great misinformation on the outcome of the data process. This is likely to be caused by the first factor that is the data having a lot of discrepancies. The discrepancy causes the data to be meaningless in terms of the trends displayed. In addition, the lack of enough points posses a challenge to the data collection and processing procedure. The data base management system can be used to concentrate data on a central point of reference.

Requests to access specific cylinders on a disk drive arrive in this order: 24, 20, 4, 40, 6, 38, and 12, and the seek arm is in

GarryVolchara [31]

Answer:

The time required to seek using First come,first served algorithm is 876 milliseconds.

The time required to seek using Shortest Seek Time First algorithm is 360 milliseconds.

The time required to seek using LOOK (initialing moving upwards) algorithm is 348 milliseconds.

Explanation:

Part a,b : First-come, first-served:

The order of the cylinders is as 10, 22, 20, 2, 40, 6, 38

10 + 12 + 2 + 18 + 38 + 34 + 32 = 146 cylinders = 876 milliseconds.

ii) Shortest Seek Time First:

The order of the cylinders is as 20, 22, 10, 6, 2, 39, 40

0 + 2 + 12 + 4 + 4 + 36 + 2 = 60 cylinders = 360 milliseconds.

iii) LOOK (initialing moving upwards):

The order of the cylinders is as 20, 22, 38, 40, 10, 6, 2

0 + 2 + 16 + 2 + 30 + 4 + 4 = 58 cylinders = 348 milliseconds.

This function receives first_name and last_name, then prints a formatted string of "Name: last_name, first_name" if both names a

pishuonlain [190]

Answer:

Following are the program in the C++ Programming Language.

//set header file

#include <iostream>

//set namespace

using namespace std;

//define class

class format

{

//set access modifier

public:

//set string type variable

string res;

//define function

void names(string first_name, string last_name)

{

//set if-else if condition to check following conditions

if(first_name.length()>0 && last_name.length()>0)

{

res="Name: "+last_name+", "+first_name;

}

else if(first_name.length()>0 and last_name.length()==0)

{

res="Name: "+first_name;

}

else if(first_name.length()==0 and last_name.length()==0)

{

res="";

}

//define function to print result

void out(){

cout<<res<<endl;

}

};

//define main method

int main() {

//set objects of the class

format ob,ob1,ob2;

//call functions through 1st object

ob.names("John","Morris");

ob.out();

//call functions through 2nd object

ob1.names("Jhon","");

ob1.out();

//call functions through 3rd object

ob2.names("", "");

ob2.out();

}

Output:

Name: Morris, John

Name: Jhon

Explanation:

Following are the description of the program:

Define class "format" and inside the class we define two void data type function.

Define void data type function "names()" and pass two string data type arguments in its parameter "first_name" and "last_name" then, set the if-else conditional statement to check that if the variable 'first_name' is greater than 0 and 'last_name' is also greater than 0 then, the string "Name" and the following variables added to the variable "res". Then, set else if to check that if the variable 'first_name' is greater than 0 and 'last_name' is equal to 0 then, the string "Name" and the following variable "first_name" added to the variable "res".
Define void data type function "out()" to print the results of the variable "res".

Finally, we define main method to pass values and call that functions.
