Here is a code segment that reads input from infile.dat and sends output to outfile.dat. What changes are necessary to make the output go to the screen? (The input is still to come from infile.dat.)
//Problem for Self Test. Copies three int numbers
//between files. #include <fstream> int main( )
{
using namespace std;
ifstream inStream;
ofstream outStream;
inStream.open(“infile.dat”);
outStream.open(“outfile.dat”);
int first, second, third;
inStream >> first >> second >> third;
outStream << “The sum of the first 3” << endl
<< “numbers in infile.dat is ”<< endl
<< (first + second + third) << endl;
inStream.close();
outStream.close();
return 0;
}

- Please answer JAVA OOP question below: An Employee has a name, employee ID, and department. An Employee object must be created with all its attributes. The UML diagram is provided below: - name: String - employeeId: String - department: String + Employee(name: String, employeeId: String, department: String) + setName(name: String): void + setEmployeeId(employeeId: String): void + setDepartment(department: String): void + getName(): String + getEmployeeId(): String + getDepartment(): String + toString(): String A faculty is an Employee with an additional field String field: rank Assuming the Employee class is fully implemented, define a Professor class in Java with the following: Instance variable(s) A Constructorarrow_forwardDevelop a C++ program that execute the operation as stated by TM for addition of two binary numbers (see attached image). Your code should receive two binary numbers and output the resulting sum (also in binary). Make sure your code mimics the TM operations (dealing with the binary numbers as a string of characters 1 and 0, and following the logic to increase the first number and decreasing the second one. Try your TM for the following examples: 1101 and 101, resulting 10010; and 1101 and 11, resulting 10000.arrow_forwardI need to define and discuss the uses of one monitoring or troubleshooting tool in Windows Server 2019. thank youarrow_forward
