this is a program use to calculate the marks and grades of 25 students using array.

this is wat my code looks like

#include <iostream>;

#include <string>;

using namespace std;



int main()

{

int a,b;

char grade;

double mark, sum;

string name;

string studname[25];

double marks[5];

char grades[25];



for (a = 0; a < 25; a++)

{

    sum = 0;

    cout << "Please enter the name of the student : n";

    cin >> name;

    studname[a] = name;



    for (b = 0; b < 5; b++)

    {

        cout << "PLease enter the assignment" << b + 1 << "marks : n";

        cin >> mark;

        marks[b] = mark;

        sum = sum + mark;

    }



    if (sum >= 80)

        grade = 'A';

    else if (sum >= 60)

        grade = 'B';

    else if (sum >= 50)

        grade = 'C';

    else if (sum >= 40)

        grade = 'D';

    else

        grade = 'F';

    grades[a] = grade;



    cout << "Sum of assignment marks : " << sum << endl;

    cout << "Grade : " << grade << endl;

}



system("pause");

return 0;

}

the output shows :

1>c:usersktychsourcereposlab 5lab 5source.cpp(1): warning C4067: unexpected tokens following preprocessor directive - expected a newline

I believe it's because of the ; after the include.

E.g. it's the grammar and you must refer to spec and compiler because as an implementation detail the compiler can choose to ignore that.
