The Program in C++ Program to find Second largest element in a given array is given below:
#include <iostream>
#include <algorithm>
int main() {
int n;
std::cout << "Hello Codeauri Family,Enter the number of elements here to find out the second largest element: ";
std::cin >> n; // Read the size of the array
int a[n];
std::cout << "Well,Enter the elements here: ";
for (int i = 0; i < n; i++) {
std::cin >> a[i]; // Read the elements of the array
}
std::sort(a, a + n); // Sort the array
int secondLargest = a[n - 2]; // The second largest element is the second to last element after sorting
std::cout << "Okay, the second largest element is: " << secondLargest << std::endl;
return 0;
}
Output:
Hello Codeauri Family,Enter the number of elements here to find out the second largest element: 3
Well,Enter the elements here: 10765
24098
1067
Okay, the second largest element is: 10765
Pro-Tips💡
In this program, after reading the elements of the array, it sorts the array in ascending order using the std::sort function from the algorithm library.
The second largest element is then the second to last element in the sorted array.
