[c++] string to multiple integers

[Juggernautilus]

Hello,

 

Lets say I have an input string that looks like this "3-5-2", without the quotes, and I need to separate it to 3 integers a b c so a=3, b=5, c=2.

 

I would search google if I knew what keywords to look for. This might be pretty basic for most programmers but knowing this would solve a lot of stuff for me, thanks!

Right, so I Googled a bit and found this:

I have no experience with C++, so couldn't help you out further.

Don't know about C++ (I'm more at home with Java/C#), but my idea is to split the string to a string array (use the '-' as a split parameter) and then parse the string array to an int array... Not really elegant, but it's an idea to think about.

Changed the answer's code a little and used stoi to convert strings to int. I know there must be a better soloution but this works for me. Thanks.

Removed I misread

 

You mean c++'s alternative of .split("a") that would return an array?

You need scanf().

#include <stdio.h>void main() {  int a;  int b;  int c;  scanf("%d-%d-%d", &a, &b, &c);  printf("%d\n", a);  printf("%d\n", b);  printf("%d\n", c);}
