largest element in array code example

Example 1: find maximum number in array

#include <stdio.h>
int main() {
    int i, n;
    float arr[100];
    printf("Enter the number of elements (1 to 100): ");
    scanf("%d", &n);

    for (i = 0; i < n; ++i) {
        printf("Enter number%d: ", i + 1);
        scanf("%f", &arr[i]);
    }

    // storing the largest number to arr[0]
    for (i = 1; i < n; ++i) {
        if (arr[0] < arr[i])
            arr[0] = arr[i];
    }

    printf("Largest element = %.2f", arr[0]);

    return 0;
}

Example 2: find the maximum number from an int Array

---without sort method---
public static int maxValue( int[]  n ) {

int max = Integer.MIN_VALUE;

for(int each: n)

if(each > max)

max = each;

 
return max;
  
---with sort method---
public static int maxValue( int[]  n ) {

Arrays.sort( n );

return  n [ n.lenth-1 ];

}

Example 3: max element in array

int max;
max=INT_MIN;

for(int i=0;i<ar.length();i++){
	if(ar[i]>max){
    	max=ar[i];
    }

Example 4: kth largest element in an array javascript

function nthlargest(arra,highest){
			var x = 0,
				y = 0,
				z = 0,
				temp = 0,
				tnum = arra.length, 
				flag = false, 
				result = false; 
   
			while(x < tnum){
				y = x + 1; 
				
				if(y < tnum){
					for(z = y; z < tnum; z++){
						
						if(arra[x] < arra[z]){
							temp = arra[z];
							arra[z] = arra[x];
							arra[x] = temp;
							flag = true; 
						}else{
							continue;
						}	
					}					
				}
				
				if(flag){
					flag = false;
				}else{
					x++; 
					if(x === highest){ 
                      
						result = true;
					}	
				}
				if(result){
					break;
				}
			}

			return (arra[(highest - 1)]);	
		}
		
console.log(nthlargest([ 43, 56, 23, 89, 88, 90, 99, 652], 4));
