input value get index

[sebz92]

hello all,
im trying to get the index of a value by inputting the value:
for example if i have

int arr[5]={22, 85, 58, 78, 69};

indexOfItem(arr, 78);

and have the output be:

the index of the item is: 3

thanks in advance!!

so

void indexOf(int arr[], int lenght){  
	int temp=0;
	int e;
	for (int i = 0; i < lenght; i++)
	{
		if (arr[i]>temp){
			temp = arr[i];
			e = i;
		}

	}
	cout << "the index is : " << e << " and the value is : " << temp << endl;
   }

// arr[] is your array and length is the length of the array  

ok i figured it out! this is the answer!
