C++ How do I print a .txt file verbatim?

set print repeats 0

(gdb) p "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"
$6 = 'a' <repeats 30 times>
(gdb) set print repeats 0
(gdb) p "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"
$7 = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"
(gdb) set print repeats 10
(gdb) p "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"
$8 = 'a' <repeats 30 times>

string EscapeIt(string value) {
  var builder = new StringBuilder();
  foreach (var cur in value) {
    switch (cur) {
      case '\t': 
        builder.Append(@"\t");
        break;
      case '\r': 
        builder.Append(@"\r");
        break;
      case '\n':
        builder.Append(@"\n");
        break;
      // etc ...
      default:
        builder.Append(cur);
        break;
    }
  }
  return builder.ToString();
}

string x = @"start "" end";

let x = @""Hello""

string x = @"1"+"";

Console.WriteLine(@"Foo {0}", "Bar");

var x = [["A", "B", "C"], ["D", "E", "F"]];
var string = JSON.stringify(x);
