C++11!! Mini benchmark to compare std::set and std::unordered_set. You may need a bigger list of word for better results.

fstamour / escapeChar.cpp
Last active December 16, 2015 11:28
A simple helper function to handle escapes in parsing, you may choose the kind of error handling you want (by return value or by exception) and it is really easily converted to C.
//#include <stdexcept>
/// @warning The parameter is also the return value.
/// @return true if the escape sequence was valid, false otherwise
bool escapeChar( char& c ) {
switch( c ) {
case 't':
c = '\t';
break;
case 'n':

char c = in.peek();
if( c == '.' ) {
in >> f;
f += i;
return false;

fstamour / atoi.c
Created April 24, 2013 01:12
Minimal C code to read an int from a stream. This doesn't comply with the standard atoi at all, but it's just for simplicity.
int i = 0;
//FILE* in = stdin;
char c = getc(in);
while( c >= '0' && c <= '9' ) {
//i = i*10 + (c - '0'); //Equivalent to the line below
i = (i<<3)+(i<<1)+c-'0';
c = getchar();
}
