Interger converted to String
Author
Hi, I am working on a SDL game engine and it is going very well, except one problem. I caculate my frames per second and want to convert it to a string to send to my text print out function which accepts a string for the message. I know how to convert it into a int to a char but I want to convert a int to a string.
Hope you understand, can anyone help?
What language? I''ll assume C (ISO).
int Integer = 12345;char String[12];snprintf(String,12,"%d",Integer);
Author
C++
I knew about that but what about something like
int Integer = 12345;
string strInteger;
snprintf(strInteger,"%d",Integer);
I dont wanna use char bla[12], instead I was to use a string. (Yes I know strings are all chars at heart but I want a string object not a char array, kinda the same thing but I hope it makes some sense.)

How about the following:

int main(int argc, char *argv[]){ int iValue; char szTempString[1000]; // fill iValue with an integer, frame rate, value . . . string testing(itoa(iValue, szTempString, 10)); cout << testing; return 0;} ------

C++ - Use stringstream
string getFPS(){//calculate fps in variable frames stringstream input; input<<frames; return input.str();} Why make it simple when you can make it sooo nice and complicated?
C++, using the Boost library.
You write it out just like any other C++ cast.
