Changing Array using Pointer

Question

I'm trying to change the values of an array using a pointer in a function but when I call the function an error occurs. Can anyone find the solution?
This is the code I wrote in C++ language:
#include<iostream>
using namespace std;
int lut[240] ={240 values} ;
void chng(int *arr[], int c) {
int j;
for(j=0;j<=239;j++) {arr=&lut[j]; }
for(j=0;j<=239;j++) {*arr[j] =*arr[j] +c;}}
int main() {
int i;
chng(&lut, 25) ; --->error
for(i=0;i<=239;i++) {cout<<lut[i] <<" ";}
return 0;}

Answer 1

don't call array lut by reference while calling the function . Call it like :- chng(lut,25)
I hope it will work correctly then.
