runs all ifs??? [*resloved*]

Code:

---

if(argc>2)
{
if(argv[1]="open")
        {
                ...
        }
        else if(argv[1]="new")
        {
                ...
        }
}

---

when i enter in "cmdline.exe open c:\test.txt", it runs fine, when i run £cmdline.exe new c:\newtext.txt" it trys to open c:\newfile.txt? is this because im trying to use a string in the "if(argv[1] = ..." part??



Thanks:)

You are using the assignment operator in the if statement. You MEANT ==.

Second, unless you converted your command line arguments to string objects in C++, you cant use the == operator to determine equality of the strings. Use the strcmp function instead.

Maybe somethig like this:

Code:

---

#include <iostream.h>
#include <string.h>

int main(int argc, char * argv[])
{
char * Str1 = "open";
char * Str2 = "new";

if(argc > 2)
        {
        if(strcmp(argv[1], Str1) == 0)
                {
                //...
                }
        else if(strcmp(argv[1], Str2) == 0)
                {
                //...
                }
        else
                cout<<"Wrong usage."<<endl;
        }
else
        cout<<"Wrong usage."<<endl;

return 0;
}

Hope this helps. :)

Yeah, though you dont have to store those strings before using them in the strcmp function... you can simply call it like so:

Code:

---

strcmp(argv[1], "new") == 0

cheers thanks for the help :)

<iostream> not <iostream.h>.
