Lab 6.1: Working with Single Dimension Arrays

Using the code below, complete the code and run the program.

The following is the code to be used:

// This program will read in a group of test scores( positive integers from 1 to 100)

// from the keyboard and then calculates and outputs the average score

// as well as the highest and lowest score. There will be a maximum of 100 scores.

// PLACE YOUR NAME HERE

#include

using namespace std;

// Function prototypes

float findAverage (const GradeType, int); // finds average of all grades

int findHighest (const GradeType, int); // finds highest of all grades

int findLowest (const GradeType, int); // finds lowest of all grades

int main( void )

{

int GradeAray[100]; + // an integer array of 100 elements

int numberOfGrades; // the number of grades read.

int pos; // index to the array.

float avgOfGrades; // contains the average of the grades.

int highestGrade; // contains the highest grade.

int lowestGrade; // contains the lowest grade.

// Read in the values into the array

pos = 0;

cout << "Please input a grade from 1 to 100, (or -99 to stop)" << endl;

cin >> GradeAray [pos];

while (GradeAray [pos] != -99)

{

// Fill in the code to read the grades

}

numberOfGrades = _________; // Fill blank with appropriate identifier hint: pos is last grade in

// call the function to find average

avgOfGrades = findAverage(GradeAray, numberOfGrades);

cout << endl << "The average of all the grades is " << avgOfGrades << endl;

// Fill in the call to the function that calculates highest grade

cout << endl << "The highest grade is " << highestGrade << endl;

// Fill in the call to the function that calculates lowest grade

// Fill in code to write the lowest to the screen

return 0;
