Question

PLEASE DESCING A FLOWCHART IN FLOWGORITHM

Test Average and Grade

Write a program that asks the user to enter five test scores. The program should display a letter grade for each the five test score and the average test score. Design the following functions in the program :

-calAverge This function should accept five test scores as arguments and return the average of the scores.

-determineGrade This function should accept a test score as an argument and return a letter grade for the score (as a string), based on the following grading scale

Score Letter Grade

90-100 A

80-89 B

70-79 C

60-69 D

Below 60 F

THANK YOU

Answer 1

Following is the design of the flowchart for the given problem using Flowgorithm.

Main function:

calAverage function:

determineGrade function:

Output:

95
63
86
72
45
72.2
A
D
B
C
F

C++ code:

#include <iostream>
#include <sstream>
#include <string>
#include <cstdlib>
#include <cmath>

using namespace std;

// Headers
string toString (double);
int toInt (string);
double toDouble (string);
double calAverage(int[] m);
string determineGrade(int m);

int main() {
int marks[5];
int i;
string grade[5];
  
for (i = 0; i <= 4; i++) {
cin >> marks[i];
grade[i] = determineGrade(marks[i]);
}
double average;
  
average = calAverage(marks);
cout << average << endl;
for (i = 0; i <= 4; i++) {
cout << grade[i] << endl;
}
return 0;
}

double calAverage(int[] m) {
double average;
  
average = 0;
int sum;
  
sum = 0;
int i;
  
for (i = 0; i <= 4; i++) {
sum = sum + m[i];
}
average = (double) sum / 5;
  
return average;
}

string determineGrade(int m) {
string grade;
  
if (m >= 90 && m <= 100) {
grade = "A";
} else {
if (m >= 80 && m <= 89) {
grade = "B";
} else {
if (m >= 70 && m <= 79) {
grade = "C";
} else {
if (m >= 60 && m <= 69) {
grade = "D";
} else {
grade = "F";
}
}
}
}
  
return grade;
}

// The following implements type conversion functions.
string toString (double value) { //int also
stringstream temp;
temp << value;
return temp.str();
}

int toInt (string text) {
return atoi(text.c_str());
}

double toDouble (string text) {
return atof(text.c_str());
}
