Write strings in a file with quotes between quotes

Question

what I am doing is writing a .js file with c++ and it will be used in a .html file to draw an organizational chart. I am actually making an abstract syntax tree. for this, I write the tree nodes in a js file like the following

var nodes = [
    "int main(){", 
    "String str = "hello 'Jane'";", 
    "}"
]

there is a problem with the quotes. How do I get the following output with cpp.

var nodes = [
    "int main(){", 
    "String str = \"hello \'Jane\'\";", 
    "}"
]

Answer 1

Write a function called "escape".

  int escape(char *out, size_t sz, const char *in)
  {
     int i = 0;
     int j = 0;

     for(i=0;in[i];i++)
     {
        if(j > sz - 2)
          /* output buffer too small */
        switch(in[i])
        {
           case '\n'; out[j++] = '\\'; out[j++] = 'n'; break;
           case '\\'; out[j++] = '\\'; out[j++] = '\\'; break;

           ...

            default: out[j++] = in[i]; break; 
        }
     }
     out[j++] =0;
     return j;
  }

for read and write json file you can use boost or QT, I have usually used QT. for example:

QJson json;
//write jeson
json["test1"] = "hello";
json["test2"] = "jan";
//read from json file
cout<<json["test1"];
cout<<json["test2"];
