Your program takes as input a $3-$variable Boolean function in the form of a

sum$-$of$-$products. For example, the input can look like $$AB$+$AB$$C$$

$+$A$$B$$C$.$ The double quotations are needed so that the $$ is taken as

a regular character, negating the preceding variable, and not considered a

special character.

$$ The evaluation of each term, e$,$g$.,$ AB$$C$,$ is done in a separate function,

called, evalTerm$($int A$,$ int B$,$ int C$,$ char $*$term$)$ that return the

Boolean value $(0$ or $1)$ of the corresponding term.

$$ Your program should print the Boolean function followed by its truth

table.
