How to use itoa in C

Question

Can anybody tell me how to use itoa function in C?

The prototype is:

char*itoa(int_Val,char*_DstBuf,int_Radix)

I think that int_Val is the value that I want to convert char*_DstBuf, is the string where I want to store the result But what is int_Radix?

Answer 1

It is the base to convert to

10 - Decimal 16 - Hexidecimal 8 - Octal
