Converting Strings To Integer In Linked List (C Programming)

[Vishy8015]

Does anybody know how I could get a string value from a file convert it to integer so I can do calculations and stuff, any help will be greatly appreicated

This is the code I got so far

temp_totalprice1=atoi(Stock.RetailPrice);
temp_quantitysold1=atoi(temp_quantitysold);
temp_totalprice1=temp_totalprice1*temp_quantitysold;

On the above code it doesn't assign the value of (Stock.RetailPrice) to temp_totalprice

Have you tried using an operator with it with a integer?

edit:
I dont know if this will work with the int, but i just read that you could use (double) to convert a int into a double.
so im not sure if this will work from string to int.

(double)integer_variable

it wouldn't hurt if you actually showed us the atoi method. and what type is temp_totalprice1?

here's one way of converting a string to int

int integerValue = Integer.parseInt(stringValue);

atoi() is a part of the C standard library, it converts a null terminated string to an integer.

It would help to know how RetailPrice is defined and used before the problem line.

strtol or strtod would be better choices.
man strtol (http://www.rt.com/man/strtol.3.html)
man strtod (http://www.rt.com/man/strtod.3.html)

You can check if the value were assigned properly if you use the second argument.

whoops nvm, just realized the thing in in paranthesis in his thread title, i haven't touched C since my freshmen year in college, so it's best to ignore my above post on converting string to int, as my example is in java.
