In C++ , is it possible to pass a var as a argument ?

Example :





#include %26lt;iostream%26gt;


#include %26lt;stdlib.h%26gt;


#include %26lt;string.h%26gt;


using namespace std;





class test


{


private:


public:


int func(pass_string){





pass_string = " Hello " ;





} };




















int main()


{


test test1;





string pass_string








test1.func(pass_string);














system("pause")


return 0;


}

In C++ , is it possible to pass a var as a argument ?
you cant pass the string "hello" as an argument, BUT you can pass a pointer to the string, which contains "hello".





char pass_string[] = "Hello"; //or could be CString type


int func(char *pChar);





int main()


{


func(pass_string);


}





func(char* pChar)


{


cout%26lt;%26lt;pChar%26lt;%26lt;endl;


}
Reply:Yes, it is possible to pass a variable by reference.


Your method should be declared as:


int func(string%26amp; arg);


PS. Your example has many errors.
