Hi all :)
I have some problems how i can approach this solution correctly:p
First of all i created a string class with use of sprintf_s() etc
Now i want to parse a numeric or decimal or float to char*, but the problem is that i want the correct sized char* buffer for that variable
I dont know if it is possible or if it isnt needed
here are my parse functions:
static String Parse(int number)
{
// create result string object
String result;
// create buffer for the parsed string
result.m_szBuffer = new char[100];
// parse number into buffer
sprintf_s(result.m_szBuffer, 10, "%i", number);
result.m_iLength = (int)strlen(result.m_szBuffer);
// return the results
return result;
}
static String Parse(double decimal)
{
// create result string object
String result;
// create buffer for the parsed string
result.m_szBuffer = new char[100];
// parse number into buffer
sprintf_s(result.m_szBuffer, 10, "%d", decimal);
result.m_iLength = (int)strlen(result.m_szBuffer);
// return the results
return result;
}
static String Parse(float real)
{
// create result string object
String result;
// create buffer for the parsed string
result.m_szBuffer = new char[100];
// parse number into buffer
sprintf_s(result.m_szBuffer, 10, "%f", real);
result.m_iLength = (int)strlen(result.m_szBuffer);
// return the results
return result;
}
Now the problem is the
// create buffer for the parsed string
result.m_szBuffer = new char[100];
if i now have a very large number to parse then maybe it cannot hold the number. but if it is instead very small then i allocate useless space of memory :P
If i want to save memory etc i think i have to get the length of the passed variable to create the correct buffer. but i dont know how todo it :
Maybe iam doing something completly wrong forgive my noobness that time :D
Thx in advance
