God I hate C++

[lukatmyshu]

Using C++ how would I make a string have the same value as a an float ... so if I have a float x = .5 how do I get a string to have the same value?

Look up sprintf() and/or <sstream>

 

[eklass]

if you just want to convert the value and not output it, look in your class book or google for "typecasting" or "casting" or "cast"

 

[PCHPlayer]

stringstream ss;

float x = .5;

ss << setf(1) << x;

string s = ss.c_str();

// This is close, but may be off a little since I don't have my book in front of me.

sprintf will do it. Do a google search for "man sprintf"

 

[glugglug]

you could just use _gcvt.....

You hate it because the string class << doesn't override having a float in the picture? Jeez...

I wrote a program which goes through and downloads pictures for comics every day of the year, until they changed it to random numbers, instead of just the dates. That was the life.

Just use string streams.
Here's a quick and dirty example:


#include <iostream>
#include <sstream>
#include <string>
using namespace std;
int main()
{
stringstream x;
float y = 1e29;
string z;
x << y;
x >> z;
cout << z << endl;
return 0;
}
