List and explain three ways study groups benefit your learning.
Answer:
Studying in groups can have many effective outcomes and be beneficial. Here are some ways studying in a group is benefical,
1. More support, limits chances of procrastination
With many people, everyone is assigned a role or there is more determination by all peoples to get the work done than an individual being the only one responsible than many trying to accomplish the completion of the project.
2. More people means more parts can get done effectively and taking notes is easier.
More people allow the work (depending on the project of assignment) for the work to get more focused and worked on faster with the designated roles given.
3. More interactive and allows (sometimes an enjoyable times) and to even learn faster than independently.
People, not all however, might like the company, there's support and even people skills is enhanced by being in the group.
Write a program that reads the student information from a tab separated values (tsv) file. The program then creates a text file that records the course grades of the students. Each row of the tsv file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student. A sample of the student information is provided in StudentInfo.tsv. Assume the number of students is at least 1 and at most 20.
The program performs the following tasks:
Read the file name of the tsv file from the user.
Open the tsv file and read the student information.
Compute the average exam score of each student.
Assign a letter grade to each student based on the average exam score in the following scale:
A: 90 = < X o
B: 80 = < x < 90
C: 70 = < X < 80
D: 60 = < x < 70
E: X < 60
• Compute the average of each exam.
• Output the last names, first names, exam scores, and letter grades of the students into a text file named report.txt. Output one student per row and separate the values with a tab character.
• Output the average of each exam, with two digits after the decimal point, at the end of report.txt. Hint: Use the setprecision manipulator to format the output.
Ex: If the input of the program is:
StudentInfo.tsv
and the contents of StudentInfo.tsv are: 70 45 59
Barrett Edan 96 97 88
Bradshaw Reagan 73 94 80
Charlton Caius 88 61 36
Mayo Tyrese 90 86 45
the file report txt should contain
Barrett Edan 70 45 59 F
Baadha Boagan 9e 157 89 A
Charlton Caius 73 94 80 B
Mayo and Tyrese 58 61 36 D
Stern and Brenda 90 36 45 C
Average midterm 83.40, midterm2 76.60, final 61.60
In this exercise we have to use the knowledge of the JAVA language to write the code, so we have to:
The code is in the attached photo.
So to make it easier the code can be found at:

}
double average = sum/3;
if(average>=90 && average<100)
this->grade = 'A';
else if(average>=80)
this->grade = 'B';
else if(average>=70)
this->grade = 'C';
else if(average>=60)
this->grade= 'D';
else this->grade = 'F';
}
};
// This function reads the file , and creates a vector of Students data

st.marks[1] = stoi(row[3]);
st.marks[2] = stoi(row[4]);
st.calculate_grade();
list.push_back(st);
}
fin.close();
return list;
}
// This function takes filname to be output as input, and list of student
void writeFile(string filename, vector list){

Each openning parenthesis (, or [, or { must be macthed by a corresponding closing parenthsis ), or ] or }. For example, 12 { 34 / [ 6 * ( 55 - 10 ) / ( 100 20 ) ] } has matched pairs of parentheses, while 12 { 34 / ( 6 * ) ] } does not. Write a function to check whether an input math expression has matched parentheses. The header of the function is given as follows:
