Question

For C++, This is part of a larger program but I only need help with writing and calling this function. I am having trouble finding information on calling a 2d vector.

Given :

const int NUM_STUDENTS =3; 

string Students[NUM_STUDENTS] = {"Tom","Jane","Jo"};
vector <int> grades[NUM_STUDENTS] {{78,98,88,99,77},{62,99,94,85,93}, {73,82,88,85,78}};

4. Write a function called displayGrades that takes the student array and grade vector as parameters and displays the grades in the format in the sample run below. (15 points).

Output: Name Assign. 1 Assign. 2 Assign. 3 Assign. 4 Assign. 5
Tom 78 98 88 99 77
Jane 62 99 94    85 93
Jo 73 82 88 85 78

Answer 1

#include <iostream>
#include <vector>
using namespace std;
const int NUM_STUDENTS =3;
void displayGrades(string students[], vector<int> grades[]) {
cout<<"Name Assign. 1 Assign. 2 Assign. 3 Assign. 4 Assign. 5"<<endl;
for(int i=0;i<NUM_STUDENTS;i++) {
cout<<students[i]<<" ";
for(int j=0;j<grades[i].size();j++) {
cout<<grades[i][j]<<" ";
}
cout<<endl;
}
}
int main()
{
  
string Students[NUM_STUDENTS] = {"Tom","Jane","Jo"};
vector <int> grades[NUM_STUDENTS] {{78,98,88,99,77},{62,99,94,85,93}, {73,82,88,85,78}};
displayGrades(Students, grades);

return 0;
}

Output:

$g++ -o main *.cpp
$main
Name Assign. 1 Assign. 2 Assign. 3 Assign. 4 Assign. 5
Tom 78 98 88 99 77 
Jane 62 99 94 85 93 
Jo 73 82 88 85 78
