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; }
