Find second largest

Question

Hi anyone know how to find second largest

#include <iostream>
using namespace std;

int index_Of_Second_Largest_Element(int x[]){

int first;
int second;
int temp;
int len = sizeof(x)/sizeof(x[0]);

for(int i = 0; i < len ; i++){
if(i < 1) {
if(x[i] > x[i+1]) {
first = x[i];
second = x[i+1];

}
else{
first = x[i+1];
second = x[i];
}
}
else if(i > 1){
if(x[i] > first){
second = first;
first = x[i];
}
}

}
return second;
}

int main () {

int num [] = {5,9,8,2,3,11,10};

int second_larger = index_Of_Second_Largest_Element (num);

cout << "Index of Second Largest Element " << second_larger << endl;

return 0;
}

Hi nur nazhan
Try to search the forum by 'second largest' term (without quotes), this topic had been posted several times, in different languages and slight modifications 👍

P.S. And please tag C++ rather than 'helpppp' up there ☝
