Information technology is more global than other fields. Jesse's diverse college background could help him remain culturally sensitive during communications with collaborators from other parts of the world.
Answer:
The program to this question can be given as:
Program:
#include <iostream> //header file
using namespace std; //using namespace
double MphAndMinutesToMiles(double milesPerHour, double minutesTraveled) //defining method
{
return (minutesTraveled/ 60.0)*milesPerHour; //return value.
}
int main() //defining main method
{
double milesPerHour,minutesTraveled; //define variable
cout<<"Enter miles per hour :";
cin >> milesPerHour;
cout<<"Enter travelling minutes :";
cin >> minutesTraveled;
cout << "Miles: "<< MphAndMinutesToMiles(milesPerHour, minutesTraveled)<< endl;
return 0;
}
Output:
Enter miles per hour :12
Enter travelling minutes :20
Miles: 4
Explanation:
The explanation of the above C++ program can be given as:
- In the first header file is include the function is define that is "MphAndMinutesToMiles". This function accepts two parameters that are "milesPerHour and minutesTraveled".
- Both parameter datatype is double and the function return type is also double. Inside a function calculate miles and return its value.
- In the main method, two variable defines that takes value from the user side and pass into the function. To print function return value we use "cout" function that prints function return value.
Answer:
operating systems
Explanation:
The operating systems is shortly known as OS. It is a system software which manages the software resources of the computer, computer hardware and also provides some common services for the various computer programs.
Most of the operating systems available in the market provides some common utility programs such as the search program, a backup program and a storage management program also.
Some common operating systems are : Linux, Microsoft Windows, Ubuntu, macOS, Unix, and many more.
Answer:
b) Bounded Waiting
Explanation:
int currentThread = 1;
bool thread1Access = true;
bool thread2Access = true;
thread1 { thread2 {
While (true) {
While (true)
{
while(thread2Access == true)
{
while(thread1Access == true)
{
If (currentThread == 2) {
If (currentThread == 1)
{
thread1Access = false; thread2Access = false;
While (currentThread == 2);
While (currentThread == 1);
thread1Access = true; thread2Access = true;
} }
/* start of critical section */ /* start of critical section */
currentThread = 2 currentThread = 1
… ...
/* end of critical section */ /* end of critical section */
thread1Access = false; thread2Access = false;
… ...
} }
} }
} }
It can be seen that in all the instances, both threads are programmed to share same resource at the same time, and hence this is the bounded waiting. For Mutual exclusion, two threads cannot share one resource at one time. They must share simultaneously. Also there should be no deadlock. For Progress each thread should have exclusive access to all the resources. Thus its definitely the not the Progress. And hence its Bounded waiting.
