— I guess you want to run the loop as long the input is valid :) so in this case you should do 

while(scanf("%i", &somenum) == 1)

— 

The while loop runs as long as one input value is succesfully parsed and assigned - that should be it

— Thank you

— Haha ^^ your welcome

— Is it possible to use an if statement instead of a while loop?

— If scanf equals to 1 else …

— Sure for example: 

if(scanf("%i", &somenum)) { 
      //Okay 
} else {
     //Dammit something went wrong
}
the == 1 is implicit because 0 evaluates to false and everything else to true so 1 is true
