hey,
i need help with transforming intergers into strings. I will have 2 intergers that i will have to make into a string and then display it as a file name. how can i do this without using sprintf.
so the file name should look like this "list24to30.txt" where 24 and 30 are the intergers that were entered. can anyone help me please. Thanks.
Well, since your teacher doesn't want you to use sprintf(), you should write your own function similar to itoa() that accepts an integer and returns a string.
First, you need to be able to break an integer into its respective digits. Then, you need to change each digit to its character equivalent.

i can break the intergers into their character equavalents but i dont know how to put them together into a single string, since my intergers can range from 1 to 1000, i dont know how many character variables will be needed.
if my interger is 131, then i had,
a = 1
s = 3
d = 1
but how can i put them together into a single string.
then i had char str[] = a,s',d
which would give me a string of 131 but next time my varaible would be 13, but then the char 'a' would not be used. how can i get around that?
