Project 2write A Program That Will Ask The User To Input 3 Student Fir
Develop a C++ program that prompts the user to input three students' first names and five scores for each student. Utilize a multi-dimensional array to store the student's name, the five scores, the total score, the ceiling of the average score, and the letter grade. Implement separate functions to calculate the ceiling of the average score and to determine the letter grade using a switch statement. After all data has been inputted, display the information formatted similarly to the example below.
Paper For Above instruction
This project requires creating a comprehensive C++ program that effectively manages student data through user inputs and provides a detailed output summarizing each student's academic performance. The primary goal is to practice the usage of multi-dimensional arrays, functions for mathematical calculations, and control structures like loops and switch statements.
The program starts by prompting the user to input the first names of three students. Subsequently, for each student, the program will request five individual scores. These scores could represent assignments, tests, or other assessments. Once the scores are entered, the program calculates the total score for the student, computes the average, determines the ceiling of the average, and assigns a letter grade based on the average score.
The multi-dimensional array serves as the central data structure. Its structure might be represented as an array where each row pertains to a student, and columns store the student's name, their five scores, total, ceiling, and letter grade. For example:
```
string students[3][7]; // where:
students[i][0] = student name
students[i][1-5] = scores
students[i][6] = total
students[i][7] = ceiling of average
students[i][8] = letter grade
```
However, since standard C++ arrays are fixed in size, an alternative is to use parallel arrays or a struct, but for this assignment, a multi-dimensional array is specified.
To compute the ceiling of the average, a dedicated function takes the average as input and returns its ceiling value. The ceiling function can be implemented using `
- A: 90-100
- B: 80-89
- C: 70-79
- D: 60-69
- F: below 60
The program flow includes:
- A loop (preferably do-while) to process three students.
- Inside this loop, a for loop to input and process each student's scores.
- Functions to calculate the ceiling and assign a letter grade.
After data collection and processing, the program displays each student's information formatted similarly to the provided sample output, showing the name, total scores, average, ceiling, and letter grade.
An example output might look like:
```
Enter a student’s first name: Mike
Enter 5 scores: 100 95 98 93 90
Total = 476
Average = 95.2
Ceiling = 96
Grade = A
Enter a student’s first name: Sam
Enter 5 scores: 90 92 88 94 92
Total = 456
Average = 91.2
Ceiling = 92
Grade = A
Enter a student’s first name: Frank
Enter 5 scores: 85 80 78 81 90
Total = 414
Average = 82.8
Ceiling = 83
Grade = B
```
This comprehensive approach ensures effective practice in arrays, functions, control loops, and switch statements, providing a solid foundation in C++ programming for managing and displaying student academic data.
