Best Chapter: Performance Tuning

However, this chapter is not really about how to improve performance. It does tell few things related to a simple program, but if someone is really worried about performance, this chapter is a misnomer.

I liked this chapter, because it pervasivly depicts the idea of avoiding performance tuning while development. While it is a known advise, "first working code, then performance"; this chapter can teach the software development in a very interactive way, the same lesson.

On a footnote, this is very well written online book. The layout of book ideally matches an online experience. I read this book back to back in 10 days. I wish there were more chapters I could read (a feeling I used to get, when I used to finish reading comics book as a kid and wished the comic was longer).

Anyway, if you want to explore a different language and python is your choice, Please, do start with this book.

Operator Parsing: Nice Hack

#include 
int main(int argc, char *argv[]){

 for(i=1;i!=argc;i++){
   if(     strcmp(argv[i], "^")==0) printf(")^(");
   else if(strcmp(argv[i], "*")==0) printf("))*((");
   else if(strcmp(argv[i], "/")==0) printf("))/((");
   else if(strcmp(argv[i], "+")==0) printf(")))+(((");
   else if(strcmp(argv[i], "-")==0) printf(")))-(((");
   else                             printf("%s", argv[i]);

 printf("))))\n");
