wat is STL?

STL is Standard Template Library
like
#include <iostream>
#include <cstdlib>
#include <vector>using namespace std;
class BinaryCode
{
public:
string itoaa(int num)
{
string str;
int rem;
if (num==0)
{
str="0";
return str;
}
while(num>0)
{
rem=num%10;
rem+=48;
str=(char)rem+str;
num/=10;
}
return str;
}
int atoii(char a)
{
int num;
num=a;
num-=48;
return num;
}
vector <string> decode(string message)
{
vector <string> s1;
int num1,num2,str1=1,str2=1;
string dec_string[2];
dec_string[0]="0";
dec_string[1]="1";
for (int i=0;i<message.length();i++)
{
if (i==0)
{
num1=atoii(message[0]);
num2=(atoii(message[0]))-1;
}
else
{
if (str1==1)
num1=(atoii(message
))-(atoii(dec_string[0]))-(atoii(dec_string[0][i-1]));
if (str2==1)
num2=(atoii(message))-(atoii(dec_string[1]))-(atoii(dec_string[1][i-1]));
}
if ((num1!=0)&&(num1!=1))
{
str1=0;
dec_string[0]="NONE";
}
else
if (i!=(message.length()-1))
dec_string[0]+=itoaa(num1);
if ((num2!=0)&&(num2!=1))
{
str2=0;
dec_string[1]="NONE";
}
else
if (i!=(message.length()-1))
dec_string[1]+=itoaa(num2);
}
s1.push_back(dec_string[0]);
s1.push_back(dec_string[1]);
return s1;
}
};
