char $a,b,c$;

char$*x,y,z$;

The following line causes a type mismatch error. Why? $z=$ &a;

The line should be $z=*$ a instead of $z=$&$a$

a is declared as a char$*$ and not as a char

The line should be ${?}^{**}z=$a instead of $z=$&$a$

$z$ is declared as a char, and not as a char$*$

a is uninitialized
