Question
OddEven
Write a C++ program to sum the values in the file with respect to the input of the user. The file contains a set of numerical inputs. Read all the inputs from the file and calculate the sum of odd and even numbers based on the choice of the user.
Sample Format of the file.txt file,
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
Constraints:
Find the sum of odd numbers if the choice is 1.
Find the sum of even numbers if the choice is 2.
Get the choice from the console and display the output in the console.
Input Format:
Read an integer(choice) as an input from the console.
To sum value from the file, read the content as input from the file (file.txt)
Output Format:
Display the sum which is an integer value.
[All text in bold corresponds to input and the rest corresponds to output]
Sample File Input: (Input.txt)
Sample Input and Output 1 :
Enter the choice
1.Odd
2.Even
1
The total of all numbers is 64
Sample Input and Output 2 :
Enter the choice
1.Odd
2.Even
2
The total of all numbers is 56

- C programming (Strings and file I/O) Write a program that asks the user for 5 names and 5 scores (0 to 100) for the test, and write the names and scores to a file (test_score.txt). Read the file to find and display the average, lowest, and highest scores. If the name the user enters is "Jacob," assign 100 points to Jacob's score, regardless of what the user enters. Input Example James 80 Peter 76 Amy 67 Jacob 94 Jenny 92 Output Example Jacob has the highest score of 100. Amy has the lowest score of 67.

- PYTHON: I need to get the avg statement out of the loop so that the output prints correctly. Any suggestions. 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 B: 80 =< x < 90 C: 70 =< x < 80 D: 60 =< x < 70 F: x < 60 Compute the average of each exam.

The program executes continuously until the theater manager enters a negative number to quit. Instructions Make sure the file MovieGuide.py is selected and open. Write thewhile loop using a sentinel value to control the loop, and also write the statements that make up the body of the loop. Execute the program by clicking the Run button at the bottom of the screen.
