Nice job man!
In long int value I gets a negative value..is there any solutions??
hey am kinda new so i might ask something stupid b why the atof function need the char to have the *? like why char *double_test and not char double_test what does the * do?
what a nice vid ty
Hello i have a doubt regarding the problem
This is not really a "wholesome" resolution. The ato.() functions, while convenient and simple, can result in undefined behavior like failing to convert correctly or mistaking a hex number, etc. The strto.() family of functions are a lot safer albeit requiring three arguments (the string, a pointer to where in your input string the conversion stopped, and the base you wish to convert to.)
Thank you for zooming in, it makes it so much easier
Thank you for this. I'm looking for how to do the reverse which is converting like a long to string type
