In c++ how to code

In c++

requriements are these

***The parameters of the FindMaxNumber function are Must be a pointer variable

first : there are 10 students' math grades

a. students number : 1,2,3,4,5,6,7,8,9,10

b. math grade : 90,88, 85, 55 , 47, 92, 87, 30 , 89 , 55

seconds : find the studnet who get the higest math grade

third : math grades are only integer

last : using the integer array

write the FindMaxNumber

void main()

{ int grade[10] = { 90, 88, 85, 55, 47, 92, 87, 30, 89, 55 };

int maxGradeIndex = 0;

maxGradeIndex = FindMaxNumber(grade);

cout << "Best grade = " << grade[maxGradeIndex] << ' ';

cout << "StudentID = " << maxGradeIndex + 1 << ' '; }
