How to put two backslash in C++

Question

i need to create a function that will accept a directory path. But in order for the compiler to read backslash in i need to create a function that will make a one backslash

Answer 1

The condition if (newpath[i] = '\\') should be if (newpath[i] == '\\').

The statement newpath[i] += '\\'; will not give the intended result of concatenation. It will instead add the integral value of '\\' to newpath[i].

Moreover why are you using a char newpath[99999]; array inside the function. newpath could be std::string newpath.

int main()
{
  std::string path = "c:\\test\\test2\\test3\\test4";

  std::cout << "orignal path: " << path << std::endl;

  size_t found = 0, next = 0;
  while( (found = path.find('\\', next)) != std::string::npos )
  {
    path.insert(found, "\\");
    next = found+4;
  }

  std::cout << "path with double slash: " << path << std::endl;

  return 0;
}
