Hello there,

I have a program that has this code :

#include<stdio.h>
main(){
  int input;
  char g;

  do{
    printf("Choose a numeric value");
    printf(">");
    scanf("\n%c",&input);
    g=input-'0';
   }while((g>=-16 && g<=-1)||(g>=10 && g<=42)||(g>=43 && g<=79));

}

It basically uses ASCII manipulation to allow the program to accept numbers only .. '0' is given the value 48 by default...the ASCII value - 48 gives a ranges of numbers above (in the while statement)

Anyway, whenever a user inputs numbers AND alphabets, such as :

abr39293afakvmienb23

The program ignores : a,b,r .. But takes '3' as the first input. For a b and r, the code under the do loop repeats. So for the above example, I get :

Choose a numeric value
>Choose a numeric value>
Choose a numeric value
>3

Is there a way I can stop this ??? I tried using \n%c to scan the character and account for whitespace, but that didnt work :(

Please help

thank you very much !
