 Posted: Mon Jun 18, 2007 7:09 pm Post subject: How do I convert a number into string with C++? |
 |
|
As title. I know that I can use the old C functions itoa() or sprintf() to accomplish that, but are there any other built-in functions in C++ that can perform the same job?
Thanks in advance. |

What exactly do you mean by making a number into a string? You mean get its ascii character? That would be typecasting and you would do this.
| Code: |
#include <iostream>
using namespace std;
int main()
{
for (int x = 0; x < 256; x++) {
cout<< x<<". "<< (char)x <<" ";
}
cin.get();
}
|
Otherwise I don't exactly get what your saying. If you could give me and example it would be nice.

So I must stick to the old C functions to perform that? |

I don't even understand you unless you mean typecasting.

he means turning 12345 into "12345"- the only way to do that is with a big table with the digits and their ascii representations, and loop through every character in the string you want to fill, filling it up. that is itoa. |
