Explanation / Answer

Question week 7:-

passing an array to a method by reference :-
Here, we are sending the address of the array.So that , the caller and callee both are using the same array i.e any changes made in the array will be reflected in both places i.e callee and caller function.

passing an array to a method by value:-
Here,we are sending the copy of the array.So,that So that , the caller and callee both are using different array i.e any changes made in the array won't be reflected to the other one

Ex:-

array=[3,4,5]

call-by-reference:-

function:-
xyz(int *arr){
*arr=10;
}

xyz(arr);

now, the function array = [10,4,5]
outer array = [10,4,5]

call-by-value:-

function:-
xyz(int arr[]){
arr[0]=10;
}

xyz(arr);

now,the function array = [10,4,5]
outer array=[3,4,5]
