1. Define Prolog predicate count_a that counts the number of occurrences of atom a in a list.

?- count_a([b,c], N).

N = 0.

?- count_a([b,c,a,d], N).

N = 1.

2. I need a C program that draw the letter E shape. The user can specify the height and the width of the E. but the height should be an odd number. else print Error.

for example ( height : 5 , width: 5 ) should print the following but without the extra empty lines.

EEEEE

E

EEEEE

E

EEEEE
