Hello,

I want the program to loop a scan function if the user types anything else other than numbers..

My code is :

 do{
    printf("Enter rows\n");
    scanf("%d",&row);
  }while(row>='a' && row<='z');

but this code doesnt work .. I keep getting an error when typing in a letter. I tried manipulating around it and the whole thing loops infinitely ... What am I doing wrong ?

Please help thanks !
