## How do you find the largest number in an array?

Java program to find the largest number in an array

- Compare the first two elements of the array.
- If the first element is greater than the second swap them.
- Then, compare 2nd and 3rd elements if the second element is greater than the 3rd swap them.
- Repeat this till the end of the array.

## How do you find the largest and second largest number in an array in C?

Iterate though all array elements, run a loop from 0 to size – 1 . Loop structure should look like for(i=0; i<size; i++) . Inside loop, check if current array element is greater than max1 , then make largest element as second largest and current array element as largest. Say, max2 = max1 and max1 = arr[i] .

## What is the maximum array size in C?

The maximum size of an array is determined by the amount of memory that a program can access. On a 32-bit system, the maximum amount of memory that can be addressed by a pointer is 2^32 bytes which is 4 gigabytes.

## Which array has largest number?

Getting the maximum element of an array

Array. reduce() can be used to find the maximum element in a numeric array, by comparing each value: var arr = [1,2,3]; var max = arr. reduce(function(a, b) { return Math.

## How do you find the second largest number in an array?

Find 2nd Largest Number in Array using Arrays

- import java.util.Arrays;
- public class SecondLargestInArrayExample1{
- public static int getSecondLargest(int[] a, int total){
- Arrays.sort(a);
- return a[total-2];
- }
- public static void main(String args[]){
- int a[]={1,2,5,6,3,2};

## How do you find the maximum difference in an array?

The task is to find the maximum difference between two elements such that the larger element appears after the smaller number. That is Arr[j]-Arr[i] is maximum such that j>i. Arr[] = { 2,1,3,8,3,19,21}. Explanation − The maximum difference is between 21 and 1 and 21 appears after 1 in the array.

## How do you find the second largest number in an array in C?

The program output is also shown below.

- * C program to read elements into an array and find the.
- * largest two elements in a given array.
- int n = 0, i = 0, largest1 = 0, largest2 = 0, temp = 0;
- printf (“Enter the size of the arrayn”);
- scanf (“%d”, &n);
- int array[n];
- printf (“Enter the elementsn”);

## What is the highest number?

## What is the size of array?

To determine the size of your array in bytes, you can use the sizeof operator: int a[17]; size_t n = sizeof(a); On my computer, ints are 4 bytes long, so n is 68. To determine the number of elements in the array, we can divide the total size of the array by the size of the array element.

## Is array size fixed in C?

Arrays a kind of data structure that can store a fixed-size sequential collection of elements of the same type.

## What is the size of C structure?

A) C structure is always 128 bytes.

## How do you find a number in an array?

In this program, we are reading an array of integers and a number to find it from the given array elements. Example: Input array elements are: 10, 20, 30, 40, 50 Element to find: 30 Output: 30 found at 2 index. Input array elements are: 10, 20, 30, 40, 50 Element to find: 70 Output: 70 does not exists in the array.

## How do you find the smallest and largest number in an array?

Algorithm to find the smallest and largest numbers in an array

- Input the array elements.
- Initialize small = large = arr[0]
- Repeat from i = 2 to n.
- if(arr[i] > large)
- large = arr[i]
- if(arr[i] < small)
- small = arr[i]
- Print small and large.
