Printing a vector

[niksacokica]

I have some trouble printing a vector. I tried printf and cout but no luck so far.

 
struct car

{
	
string marka;

string model;

int obujam;

int masa;

int max_snaga_kw;

int max_snaga_ks;

int max_brzina;

float ubrzanje;

};



vector<car> allcars(56); 

 allcars[0] = { "AUDI", "R8 SPYDER", 5204, 1720, 386, 535, 313, 4.1 };



printf ("%s", allcars[0].marka);

It say: [Error] cannot pass objects of non-trivially-copyable type 'std::string {aka class std::basic_string<char>}' through '...'

Thanks in advance.

You should use the iostream library. You can start here:
http://www.cplusplus.com/doc/tutorial/files/

Then you can read this one. It covers what you really need for this issue.

I am sorry but i did not understand that article what so ever. If you could give me an example maybe i will understand.

[Thomas1965]

printf ("%s", allcars[0].marka);
printf knows how to print char *, so this should do: printf ("%s", allcars[0].marka.c_str()

It is compiled there is just one new problem.
C:\Users\korisnik\Desktop\Dream cars 2.0.cpp In function 'int main()':
And when i double click it, it goes to the first #include. Even if I reshuffle them or erase the first one. It always goes to the first one. And when I try to run it I get: Error 87: The parameter is incorrect.

you didnt post the main function, so we can't tell you what is wrong with it.
unless its missing.
c++ programs need a starting point, and that starting point is defined as int main() always.

without it, you can still compile as a library or something but it can't run and you need different compiler switches for that.

printf ("%s", allcars[0].marka.c_str());

return 0;

}

and yes I need everything that is in there between using namespace std; and struct.

[jonnin]

after removing the thankfully unused windows and dos headers and the h variable & jump buf header, it compiled and ran in the forum's online compiler.

so if it isnt working, its a problem with jump-buf or your compiler/project settings.

and knock off the printf.
#include<iostream>
std::cout << allcars[0].marka;

printf is good for printing a bunch of doubles of varying formats and sprintf is occasionally useful if you get stuck with a char* from a library. Otherwise, use strings and streams.

[Ganado]

It would help if you copy-pasted the exact error message, with the filename+line numbers each error refers to.

[niksacokica]

It is solved thanks for the help.
