c++ array pointer

void func( int* pointer){
  int i = 0 ;
  std::cout << *(pointer+i) ; // list[i]
};

int list[]={1,2,3,9};
int* pointer = list ;
func(pointer);

pointers and arrays in c++

#include <iostream>

using namespace std;

int main()
{
    int x[3] = { 5,9,20 };
    int* p = x;
    cout << p << endl;               //prints the address of x[0]
    cout << *p << endl;             //prints the value of x[0] (5)
    //printing the array
    for (int i = 0; i < 3; i++){
        cout << p[i] << endl;
        //or
        cout << *(p + i) << endl;
    }

}

C++ Pointers and Arrays

int *ptr;
int arr[5];

// store the address of the first
// element of arr in ptr
ptr = arr;

arrays and pointers

#include<stdio.h>

int main()

    int arr[5] = {10, 20, 30, 40, 50}, i;

    for(i = 0; i < 5; i++)
        printf("value stored in arr[%d] = %d
",i,*(arr+i));

    return 0;
}
