C++: cant resolve string --> string[]

**dubstar** · May 21st, 2007

attached: code in cpp file.

i'm trying to pass "userName" string to different functions for logging errors but i seem to be having trouble. I have tried numerous ways of looking at this problem and tried the last 2 days to solve it by myself. any suggestions are welcome!

help please!

thanks

You want to use something like this

Code:

void barf(std::string & narf)
{
    std::cout << "Stringy is " << narf << std::endl;
}

thereby using a reference to a std:

tring and calling using something like

Code:

int main()
{
    std::string peep = "Hello there world";
    barf(peep);
}

that kind of thing should work. X-Istence is probably better on C++ then I am at the moment I have been doing pure C for the last couple of weeks.

1>emp_strainer_1.cpp(252) : error C2664: 'sortRecords' : cannot convert parameter 14 from 'std:

tring' to 'std:

tring []'

that's the error message.

are you actually trying to pass in an array of strings?

the std:

tring wholly represents a string unlike a char[]. If you are trying to pass in an array though you need to accept a pointer to the first element of the array and possibly another parameter stating the length of the array unless it can be determined some other way. Character array based strings for example have a '\0' character at the end which can be found so you don't need to pass in the array length.

I have no clue what you are trying to accomplish, please let me know what you are trying to do.

passing the array userName[1] to all my functions. It is an array of 1 string. I am using a string because I do not want to "return" anything in my function.

the program keeps thinking it is a regular string and that i am converting it to a array

nevermind, i took that out of the program. i wasted too much time on it.

thanks for suggestions.

In your prototype for the mainMenu function, you have userName specified as a string and not an array:
...double tRate[],int flagReadRecords,string userName...

But when you try to pass it to the readRecords function, that function prototype is expecting an array.
...int menuExit[],int flagReadRecords,string userName[]...
