(Index of second largest element) Write a function that returns the index of the second largest element in an array of integers

Question

Use the following header:
int index_Of_Second_Largest_Element(int[] array)
A sample run:
4 3 6 7 9 8 10
The index of the second largest element is 4

There is something wrong with my code here 😓
#include <iostream>
using namespace std;
int index_Of_Second_Largest_Element(int array[] );
int n, num[10], largest, second, array;

int main(){
cout<<"Enter number of elements: ";
cin>>n;
for(int array=0; array<n; array++){
cout<<"Enter Array Element"<<(array+1)<<": ";
cin>>num[array];
}
cout<<"The index of the second Largest Element is: "<<index_Of_Second_Largest_Element(array[]);
}
int index_Of_Second_Largest_Element(int[] array){
if(num[0]<num[1]){
largest = num[1];
second = num[0];}
else{ largest = num[0];
second = num[1];}
for (int Array = 2; array< n ; array ++) {
if (num[array] > largest) {
second = largest;
largest = num[array]; }
else if (num[array] > second && num[array] != largest){second = num[array];} return second;}}

Answer 1

Is it your own code?

Answer 2

It's not work for finding second largest element index. It's find 2nd largest element.

And also it has some mistakes, I just corrected in other question just now..
You are passing array[] but declared num[] as array in main.
And in function array argument not matching with prototype.. Same declaring array[] as array but using num as array...,
In loop, declaring Array=2 but using array as variable.. All will cause name conflicts...

Answer 3

//corrected in other thread, look once to understand it

#include <iostream>
using namespace std;

int index_Of_Second_Largest_Element(int num[]);
int n, num[10], largest, second, array;

int main(){
cout<<"Enter number of elements: ";
cin>>n;
for(int array=0; array<n; array++){
cout<<"Enter Array Element"<<(array+1)<<": ";
cin>>num[array];
}
cout<<"The second Largest Element is: "<<index_Of_Second_Largest_Element(num); //1 edited
}

int index_Of_Second_Largest_Element(int num[]){ //2 edit

if(num[0]<num[1]){
largest = num[1];
second = num[0];
}
else{
largest = num[0];
second = num[1];
}
for (int array = 2; array< n ; array ++) { //Edit 3

if (num[array] > largest) {
second = largest;
largest = num[array];
}

else if (num[array] > second && num[array] != largest){
second = num[array];
}
} //Edit 4
return second;
}

//hope you find out mistakes.. Or reply..
