Thread: Pointer arithmetic

I am writing a program for an array with 10 elements. I am trying to get the sum of all the elements in the array. I have thoroughly confused myself. Please look at my code and make suggestions as to what I am doing wrong. I know it is in the second 'for' loop, but I know that I am making it harder than what it should be.

Code:

#include <iostream>
using namespace std;
void explanation();
int sums;


int main()
{
	explanation();
	int nums[10] = {1,2,3,4,5,6,7,8,9,10};
	int i;
	int *ptr;
	ptr=&nums[0];
    printf("The numbers in the array are:    \n");

	for (i=0; i < 10; i++)
	{
		
		printf("%d  ", nums[i]);

	}

	
	for (i=0; i < 10; i++)
	{ 
		
	sums = *ptr + nums[i];
		
	}

	printf( "%d","The sum of the elements are:   ", sums );

	return 0;
}

void explanation()
{
	printf("Written by Kelle McCan\n");
	printf("This program calculates the sum of a ten\n");
	printf("element array and then displays the sum\n");
	printf("\n");
}
