Problem # 9:

Write a program that uses a two dimensional array to initialize the scores of students. The students are arranged in five rows with five students in each row. The program inputs the row number and student number in that row and then displays the scores of the student.

Solution:

#include<iostream>
#include<conio.h>
using namespace std;
int main ()
{
    int scores[5][5], i, j, k, l;
    for(i=0;i<5;i++)
    {
            cout<<"Enter scores for the student "<<i+1<<endl;
        for(j=0;j<5;j++)
        {
            cin>>scores[i][j];
        }
    }
    cout<<"Enter row number:";
    cin>>k;
    cout<<"Enter student number in that row:";
    cin>>l;
    if(k<=5&&l<=5)
    cout<<"Score is "<<scores[k][l];
    else
    cout<<"Invalid input.";
}

Output:
