Standard array questions

  PROBLEM STATEMENT 1:
  Given an array of elements,find the sum.

CODE:

#include<bits/stdc++.h>  // header file which includes all the standard libraries
using namespace std;

int main()
{
  int a[5] = {1,2,4,6,0};
  int sum = 0;

  for(int i = 0;i < 5;i++)
  {
      cout << sum + a[i];
  }

  cout << " Sum of the elements of Array : " << sum << endl;
  return 0;
}


  PROBLEM STATEMENT 2:
  Given an array of elements,find the maximum element.

CODE:

#include<bits/stdc++.h>  // header file which includes all the standard libraries
using namespace std;

int main()
{
  int a[5] = {1,2,4,6,0};
  int max = a[0]; // Initiallization

  for(int i=0;i<5;i++)
  {
      if(a[i] > max)
      {
          max = a[i];
      }
  }

cout << "The maximum element in the array << max << endl;
return 0;
}



  PROBLEM STATEMENT 3:
  Given an array of elements,find the count of even elements.

CODE:

#include<bits/stdc++.h>  // header file which includes all the standard libraries
using namespace std;

int main()
{
    int a[7] = { 1,2,4,5,7,8,10};
    int count = 0;

    for(int i = 0;i<7;i++)
  {
      // Checking if the element is even or not
      if(a[i] % 2 == 0) 
    
      {
          count = count + 1;
      }

  }

cout << "The count of even numbers is " << count << endl;
return 0;
}


  PROBLEM STATEMENT 1:
  Given an array of elements,find the pair of elements with sum as 5.

CODE:

#include<bits/stdc++.h>  // header file which includes all the standard libraries
using namespace std;

int main()
{
    int a[5] = { 1,4,2,3,6};
    int value = 5;

    int count = 0;

  for(int i = 0;i<5;i++)
  {
      for(int j = i + 1;j<5;j++)
      {
          if(a[i] + a[j] == 5)
          {
              count = count + 1;
          }
      }
  }

cout << "The sum of the elements with sum as : " << value << " is " << count ;
return 0;
}
