Question

In visual studio Populate a one-dimensional array with the following grades in this order: 90, 61, 74, 42, 83, 51, 71, 83, 98, 87, 94, 68, 44, and 66. Use a loop to call a method from main() that adds 15 points to all student grades that are a C or above. A C is defined as a score of 70 or above. Make this happen by passing the subscript value and not the entire array. The addition of the 15 points should happen in the method and be passed back to main. Use a loop to show final values within the array. The final array values should show the new adjusted grades

Answer 1

using System.IO;
using System;

class Program
{
    //function to add 15 to grades above C
    public static int addValue(int value){
        if(value>=70)
            value=value+15;
        return value;
    }
    //main function
    static void Main()
    {
        //initial array
        int[] a=new int[]{90,61,74,42,83,51,71,83,98,87,94,68,44,66};
      
        //printing values in initial array
        Console.Write("Initial Grades: ");
        for(int i=0;i<a.Length;i++){
            Console.Write(a[i]+" ");
        }
        Console.WriteLine();
      
        //adjusting the grades
        for(int i=0;i<a.Length;i++){
            a[i]=addValue(a[i]);
        }
      
        //printing the adjusted values
        Console.Write("Adjusted Grades: ");
        for(int i=0;i<a.Length;i++){
            Console.Write(a[i]+" ");
        }
        Console.WriteLine();
      
    }
}
