Thread: skipping a character during input

i need some hints on how solve this problem:

what i want is input a series of int numbers in an array. however the input involves a comma between these number.

for example the input is

Code:

3, 1

(with a comma between 3 and 1)



without the comma, ie,

Code:

3 1

it is easy program because i just loop with scanf

but i'm getting stuck if there is a comma involved. is there a built-n function for this problem?

Code:

scanf("%d%*[, ]%d",&a,&b);
accept  
3   2
3,2
3 ,     5
But not 
3
5
use %*[, \n] if you want that ..

Always read the doc!

Note the coma in the format string...

Code:

scanf("%d,%d",&a,&b);

Yes, it's that easy.
