C string comparison problem in c++

Question

I've been having trouble with comparison in my c++ program. This is the boiled down version.

#include "stdafx.h"
#include <iostream>
#include <windows.h>
using namespace std;
int main(int argc, char *argv[])
{
    if(argc>2){cout<<"3+Args"<<endl;}else//???
    if(argc==2){
        cout<<"2args"<<endl;
        if(argv[1]=="/hide-icons"){}
        if(argv[1]=="/show-icons"){}
        if(argv[1]=="/reinstall"){setAsDefault();}
        if(argv[1]=="/?"){showPossibleCommands();}
        if(argv[1]=="/1"){cout<<"go"<<endl;FirstRun();}
    }else{showPossibleCommands();cout<<argv[0]<<endl;}
    return 0;
}

When I run "programname.exe /1", my program writes "2args" but not "go". Am I missing something obvious?

argv[1] is a char*, so by testing with == you're checking if the pointer points to the same spot as the start of the various string constants you're using... which is not going to be the case. To compare contents instead, use strcmp.
