else if statements in C++

i want to make a program which greets people differently according to their name, please dont get offended by the print statements it is just a prank for my friends. I am a beginner plz help. here's my code

#include<iostream>
#include<conio.h>

using namespace std;

int main()
{
    string a;
    cout<<"Please enter your name."<<endl;
    getline(cin, a);

    cin>>a>>endl;

   
    if(a=="daksh" || a=="Daksh"){
        cout<<"Chlaja bsdk 凸 ( ͡❛ 皿 ͡❛)凸"<<endl;
    else if(a=="Harsh" || a=="harsh"){
        cout<<"Bsdk MC behn K lode , machhar ki jhaat maki chut teri tatto ke saudagar (ง ͡❛ 皿 ͡❛)ง"<<endl;
    else if(a=="Sparsh" || a=="sparsh"){
        cout<<"Jahapana tussi geat ho , tofu kubul kro. /( ͡❛ ͜ʖ ͡❛)/"<<endl;
    else {
        cout<<"Hello ,dear"<<a<<endl;
                }
            }
        }
    }
 
return 0;
}

these are the errors , i have not posted all the errors because it is exceeding the word limit.
