Code Array

Find closest number in array

Here given code implementation process.

// C Program 
// Find closest number in array
#include <stdio.h>

//Display elements of given array
void printArray(int arr[], int size)
{
	for (int i = 0; i < size; ++i)
	{
		printf("  %d", arr[i]);
	}
	printf("\n");
}
// Returns the absolute difference of given two numbers
int absoluteValue(int a, int b)
{
	if (a > b)
	{
		return a - b;
	}
	else
	{
		return b - a;
	}
}
//Find the closest value of given element in array
void closestNumber(int arr[], int size, int element)
{
	// Find the difference between a given element and 
	// The first element of the array
	int difference = absoluteValue(arr[0], element);
	int result = arr[0];
	for (int i = 1; i < size; ++i)
	{
		if (difference > absoluteValue(arr[i], element))
		{
			// When get new minimum difference
			difference = absoluteValue(arr[i], element);
			// Get result
			result = arr[i];
		}
	}
	// Display calculated result
	printf(" Closest of element %d is : %d\n", element, result);
}
int main(int argc, char
	const *argv[])
{
	int arr[] = {
		12 , 1 , 4 , -3 , 5 , 8 , 9 , 11 , 16
	};
	// Get the size
	int size = sizeof(arr) / sizeof(arr[0]);
	// Display array element
	printf(" Array element \n");
	printArray(arr, size);
	// Test cases
	// element = -2
	closestNumber(arr, size, -2);
	// element = 7
	closestNumber(arr, size, 7);
	// element = 4
	closestNumber(arr, size, 4);
	// element = 10
	closestNumber(arr, size, 10);
	return 0;
}

Output
