Question

C++

Write a program to calculate final grade in this class, for the scores given below .

Remember to exclude one lowest quiz score out of the 4 while initializing the array.

Display final numeric score and letter grade.

Use standard include <iostream>

Implementation:

Use arrays for quizzes, labs, projects and exams.

Follow Sample Output for formatting.

May use initialization lists for arrays.

Weight distribution is as follows:

Labs: 15%

Projects: 20%

Quizzes: 20%

Exams: 25%

Final Project: 20%

Display final grade ( numeric and letter).

OUTPUT SAMPLE:

Lab grades: 80,90,100,50,50,80,100

Project grades : 95,88,90,100,100

Quiz grades: 100,90,70 //Excluded One Quiz Score so we have 3 Quizzes

Exam grades: 90, 100

Final Project Grade : 100
Bonus Points: 4

Average for Labs: 78.5714                                                                                                               

Average for Projects: 94.6                                                                                                              

Average for Quiz: 86.6667                                                                                                               

Average for Exams: 95                                                                                                                   

Final Project Score: 100                                                                                                                

Bonus Score: 4                                                                                                                          

Percentage for the class: 95.789   

Letter Grade = : A

Answer 1

Program to calculate the final grade:

#include <iostream>

using namespace std;

int main() {

int lb[] = {80,90,100,50,50,80,100};

int pg[] = {95,88,90,100,100};

int q[] = {100,90,70};

int e[] = {90, 100};

int fpg = 100;

int bonusp = 4;

float lbsum,pgsum,qsum,esum,lbs,pgs,qs,es;

lbsum = pgsum = qsum = 0;

lbs = sizeof(lb)/sizeof(lb[0]);

pgs = sizeof(pg)/sizeof(pg[0]);

qs = sizeof(q)/sizeof(q[0]);

es = sizeof(e)/sizeof(e[0]);

for(int i=0;i<lbs;i++) {

lbsum += lb[i];

}

for(int i=0;i<pgs;i++) {

pgsum += pg[i];

}

for(int i=0;i<qs;i++) {

qsum += q[i];

}

for(int i=0;i<es;i++) {

esum += e[i];

}

cout << "Average for Labs:" << lbsum/lbs << endl;

cout << "Average for Projects:" << pgsum/pgs << endl;

cout << "Average for Quiz:" << qsum/qs << endl;

cout << "Average for Exams:" << esum/es << endl;

double per;

per = ((0.15)*(lbsum/lbs)) + ((0.2)*(pgsum/pgs)) + ((0.2)*(qsum/qs)) + ((0.25)*(esum/es)) + ((0.2)*(fpg));

cout << "Bonus Score:" << bonusp << endl;

cout << "Percentage for class:" << per + bonusp << endl;

if((per+bonusp)>90) {

cout << "Letter Grade=:A" << endl;

}

return 0;
