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.
