Bruce Eckel’s Thinking in C++ is the long-standing, freely circulated book that kicked off this thread (thanks to ). It’s a solid walkthrough of core C++ concepts, but readers should note it reflects practices from the pre‑C++11 era. As observed, multiple editions exist; treat Eckel’s text as a strong foundation and supplement it with more recent references when needing modern features (move semantics, smart pointers, lambdas, <algorithm> patterns, etc.).

On the “2004 → two thousand and four” question from : ’s string-index idea will work for small, fixed formats, but a more robust, reusable approach is to process the integer in three‑digit groups (units, thousands, millions...). Basic steps: handle sign and the zero case; split the absolute value into triplets; convert each triplet using lookup tables for ones/teens/tens; append the appropriate scale word only for nonzero triplets; then join groups left to right while deciding regional rules for “and” and hyphenation. ’s offer to share code is helpful, but the triplet pattern keeps the logic clear and testable.

A compact triplet helper in C++‑style pseudocode (lookup arrays omitted for brevity):

string twoDigitsToWords(int n) {
  if (n < 10) return ones[n];
  if (n < 20) return teens[n-10];
  return tens[n/10] + (n%10 ? "-" + ones[n%10] : "");
}

string tripletToWords(int n) {
  string out = "";
  if (n >= 100) {
    out += ones[n/100] + " hundred";
    if (n%100) out += " and ";
  }
  out += twoDigitsToWords(n%100);
  return out;
}

A few practical notes tied to other replies: for ’s download-preview problem, common causes are browser preview behavior or server headers—saving the file with the browser’s Save As, trying another browser, or disabling aggressive preview/antivirus can clarify whether the file is actually delivered. For ’s “graphs in C++” query, first define whether plotting (visual charts) or graph data structures/algorithms are meant—plotting is usually easiest via a dedicated plotting library or external tool; algorithmic graph work benefits from adjacency lists and standard traversals (BFS/DFS/Dijkstra) tested on small cases.

sir
hello
actualy i am having problem in my coding
actualy i am unable to create a logic of a program
i will be thank ful if you help me.
the program is to convert the numerical nos into digital form.means if a user enters 2004 the output should be like "two thousand and four" . how can it be done
sir plz help me i will be very thankful to you

Hi
first try to convert this no. to string i.e. "2004"
Then calculate the strlen.
so strlen("2004") is 4.
assign n = strlen("2004") -1; i.e. n = 3;
then retrive character one bye one from the string.
And display the string according to the strlen.

if n == 3 then the no. corrosponds to thousands
if n == 2 then the no. corrosponds to hundreads
if n == 1 then print {...;twenty,thirty,fourty;.....}
if n == 0 then print that no.

Started reading Thinking in C++ for a while, got preatty far in, then I found version 2. The beatings may now commence.
