1)Find three largest numbers in a array :-
Given a array we have to find the largest number in the array.
#include <iostream>
#include <climits>
using namespace std;
int main(){
int n;
cin>>n;
int arr[n];
for(int i=0;i<n;i++){
cin>>arr[i];
}
int l1=-1;
int l2=-2;
int l3=-3;
for(int i=0;i<n;i++){
if(arr[i]>l1&&arr[i]>l2&&arr[i]>l3){
l1=arr[i];
}
else if(arr[i]<l1&&arr[i]>l2){
l2=arr[i];
}
else if(arr[i]<l2&&arr[i]>l3){
l3=arr[i];
}
}
cout<<l1<<" "<<l2<<" "<<l3;
return 0;
}
