Write a C++ program that calculates and prints the total grade for n assignments
as a percentage. Prompt the user to enter the value of n, followed by the number
of points received and number of points possible for each assignment . Calculate
and print the total number of points received, total number of points possible,
and the overall percentage: (total points received / total points possible) * 100.
Solution
#include <iostream>
using namespace std;
int main ()
{
int n=0,n_initial; // n will be the number of assignments entered in the system.
// since n will be counting down, I want to save n_initial as well.
int grades [2][n]; // 2 rows for possible and actual, n columns because you will have a column for each item.
// # OF EXERCISES
cout << \"How many exercises to input? > \";
cin >> n;
n_initial = n;
cout << \"n_initial = \" << n_initial;
//SCORE RECIEVED COUNTDOWN
while (n>0)
{
int x,y;
cout << endl << endl << \"Score recieved for exercise \" << n << \": \";
cin >> x;
grades [1][n] = x;
cout << endl << \"Points possible for exercise \" << n << \": \";
cin >> y;
grades [2][n] = y;
n = n-1;
}
//CALCULATION OF TOTAL AND PERCENT
int score_total=0,pointspossible_total=0,rows_1,rows_2;
//SCORE TOTAL
int xy=0;
n = n_initial;
for (int xy=0; xy < n_initial; xy++)
{
score_total += grades [1][n];
n--;
}
cout << endl << \"Score Total = \"<< score_total << endl;
//POINTS POSSIBLE TOTAL
xy=0;
n = n_initial;
for (int xy=0; xy < n_initial; xy++)
{
pointspossible_total += grades [2][n];
n--;
}
cout << \"Possible points Total = \" << pointspossible_total << endl;
cout << \"Your total is \" << score_total << \" out of \" << pointspossible_total << \", and your percentage is \" << score_total/pointspossible_total << \".\" <<endl;
system (\"pause\");
return (0)
