crashing program

Question

my program keeps crashing can you help?
heres the code:
#include<iostream>
#include<stdio.h>

int main()
{
char* a;
using namespace std;
cin>>a;
if(a=="logan")
{
cout<<"granted";
}
else{
cout<<"denied";
}
return 0;
}

Answer 1

using namespace std;

needs to be in with all the header files, not inside main.

#include <iostream>
using namespace std;
int main() { }

Answer 2

char can contain only one character. therefore it crashes I guess

Answer 3

char* is a used to iterate through a character array, there is nothing wrong with what he has written here. It generates a compile error because of the header file being inside the main, c'mon guys.

Answer 4

I don't think u can input value for pointer .

Answer 5

hey mlg, use this code

#include<iostream>
#include<string>
using namespace std;

int main()
{
string mycode;
cout<<"enter code";
cin>>mycode;

//or use if(mycode=="Logan")

if (mycode.compare("Logan"))
cout<<"granted";
else
cout<<"denied";
return 0;
}
