How to prevent users from inputting letters or numbers ?
- by ZaZu
Hello,
I have a simple problem;
Here is the code :
#include<stdio.h>
main(){
int input;
printf("Choose a numeric value");
scanf("%d",&input);
}
I want the user to only enter numbers ...
So it has to be something like this :
#include<stdio.h>
main(){
int input;
printf("Choose a numeric value");
do{
scanf("%d",&input);
}while(input!= 'something');
}
My problem is that I dont know what to replace in 'something' ... How can I prevent users from inputting alphabetic characters ?
Thanks for your help !
