Basic Array Programs in C++

Finding the Largest Element in an Array

#include <iostream>
using namespace std; 

 int main()
 {
 int num[] = {23,2,32,44,123};
 int size = sizeof(num) / sizeof(num[0]); //calculate array length

 int largest = num[0];

 for(int i=1; i<size; i++)
 {
 if(num[i]<largest)
 {
 largest = num[i];
 }
 }
 cout <<"The Largest Element: " << largest;
 return 0;
 }

Sum of All Elements in an Array

#include <iostream>
using namespace std;
int main()
{
 int num[] = {100,200,100,500,200};
 int size = sizeof(num) / sizeof(num[0]);

 int sum = 0; //consider 0 

 for(int i=0; i<size; i++)
 {
 sum += num[i];
 }
 cout <<"Sum of the element: " << sum << endl;
 return 0;
}

Sort Array Element

// arr[10] = {5,24,556,54,14,52,0,63,2,98}

#include <iostream>
using namespace std;

int main()
{
 int arr[10] = {5,24,556,54,14,52,0,63,2,98};

 for(int i=1; i<=10; i++)
 {
 for(int j=i+1; j<10; j++)
 {
 if(arr[i]> arr[j])
 {
 int temp = arr[i];
 arr[i] = arr[j];
 arr[j] = temp;
 }
 }
 }
 for(int i=1; i<=10; i++)
 {
 cout << arr[i] << " ";
 }
 return 0;
}
