Upss.. I'm really sorry I changed the Title, it was String to Int, but my function is to convert an Int Value to a String Value sorry :)
Well, there are two functions I'll post, I think they are very helpfull and I haven't found much informations about it.
//The first an main Function is a Function to Convert an Integer to String. But for this I also needed a function to get the length of an Integer, so I also wrote an extra function for this.
//Input for IntToString = Integer Value
//Input for IntLen = Integer Value
//Return for IntToString = String Value
//Return for IntLen = Integer Value

#include <string>
#include <stdlib.h>
using namespace std;
//Function to return the Length of an Integer
int IntLen(int value){
int div=1;
int len=1;
do{
div*=10;
if ((int) ( (double)value / (double)(div)) ==0){
return len;
}
len +=1;
}while(true);
}
//Function to Convert an Integer to String
string IntToString(int value){
string number;
int temp;
bool neg= false;
//Proof if the number has a negiote sign
if ((value * (-1)) > value){
value *=-1;
neg=true;
}
for (int z = IntLen(value) ;z>=1;z--){
//Modulo to get the last number
temp = value % 10;
//add Number to the String
number = ((char)(temp + 48))+ number;
//Substract the last number from the Ingeter
value = (value - temp) /10;
temp *= 10 ;
}
//Set the sign again
if (neg==true){ number="-" + number; }
return number;
}
