Question

I have a requirement, part of which needs conversion from decimal to hex.

I prefer the following way to do that thing as below:

sprintf(mcc,"%x",n);

n here will be an integer.
But my peer says it is not a good way to do that.
Instead he says to manually convert the decimal using a function,
but I did not get a good explanation about why not to use sprintf.

Are there any problems with the above method I am using?

Should I go for a function which manually converts the decimal number into hex?

Answer 1

As long as you make sure that the buffer pointed to by mcc is big enough for the resulting string, I see no problem.
