Well, C functions are not acquainted with C++ structures. You should do the following:
...
for(i = 0; i < 6; i++) {
printf("Input the number for %s =", qr_naziv[i].c_str());
scanf("%d", &br_el[i]);
}
...
Notice the call to the method c_str()
on the each std::string qr_naziv[i]
, which returns a const char *
to a null-terminated character array with data equivalent to those stored in the string -- a C-like string.
Edit:
And, of course, since you're working with C++, the most appropriate to do is to use the stream operators insertion <<
and extraction >>
, as duly noted by @MatsPetersson. In your case, you could do the following modification:
# include <iostream>
...
for(i = 0; i < 6; i++) {
std::cout << "Input the number for " << qr_naziv[i] << " =";
std::cin >> br_el[i];
}
...
