How to write a program that receives a number as characters (char) from 0-9 and A-F(A=10;B=11...)

Answer 1

Hey there! Could you show us your attempt?

Answer 2

I'm sure that there is something wrong in that but :
Char x;
Scanf("%c",x);
If (x=='A') {x=10;}
If (x=='B'l{x=11;}
.

.
If(x=='1'){x=1;}
.
