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

In this line:

if(newpath[i] = '\\')

replace = with ==.

In this line:

newpath[i] +=  '\\';

This is supposed to add a \ into the string (I think that's what you want), but it actually does some funky char math on the current character. So instead of inserting a character, you are corrupting the data.

Try this instead:

 #include 
 #include 
 #include 

int main(int argc, char ** argv) {
  std::string a("hello\\ world");
  std::stringstream ss;

  for (int i = 0; i < a.length(); ++i) {
     if (a[i] == '\\') {
       ss << "\\\\";
     }
     else {
       ss << a[i];
     }
  }

  std::cout << ss.str() << std::endl;
  return 0;
}
