Assigning variables to one another
Not only can you assign numbers to variables, you can assign other
variables to variables:
var1 = 23; var2 = var1;
The variable or value on either side of the =
symbol must
usually be of the same type. However, integers and characters will
interconvert because characters are stored by their ASCII codes (which
are integers!) Thus the following will work:
int i; char ch = 'A'; i = ch; printf ("The ASCII code of %c is %d",ch,i);
The result of this would be:
The ASCII code of A is 65
