How to convert numbers to string in C?

Question

Ive used itoa() function.. But it can only convert numbers upto 10 digits... What is the better function to use than this to input long double variable types rather than integer? Please help...

I wanted to convert Numbers to Strings.... i need it in my program...

Answer 1

Why not just use something like

#include string

string numbers;

numbers = 98431658736521876586;

Strings can be as long as you want them to be with the exception of white space and special characters. Why bother using the itoa() function in the first place?

Answer 2

enter the number as string.
or a digits array then use concatination.


to convert a string to a long number use
atol( )

to convert a string to a double number use
atof()

Answer 3

you can use atol or strtol. if you program uses unsigned integers, you can also use strtoul
