answer
(x>='0' && x<='7')
question
Assume that x is a char variable that has been declared and already given a value . Write an expression whose value is true if and only if x is a letter.
answer
(x>='A' && x<='Z') || (x>='a' && x<='z')
question
Assume that x is a char variable that has been declared and already given a value . Write an expression whose value is true if and only if x is alphanumeric , that is either a letter or a decimal digit.
Assume that c is a char variable that has been declared and already given a value . Write an expression whose value is true if (c == 'n')and only if c is an newline character .
answer
(c == 'n')
question

answer
c == ' '
question
Assume that c is a char variable that has been declared and already given a value . Write an expression whose value is true if and only if c is a tab character .
answer
(c=='t')
question
Assume that c is a char variable that has been declared and already given a value . Write an expression whose value is true if and only if c is what is called a whitespace character (that is a space or a tab or a newline-- none of which result in ink being printed on paper).
answer
(c == ' ' || c== 'n' || c == 't')
question
Assume that c is a char variable that has been declared and already given a value . Write an expression whose value is true if and only if c is NOT what is called a whitespace character (that is a space or a tab or a newline-- none of which result in ink being printed on paper).
answer
!(c == ' ' || c== 'n' || c == 't')
question

answer
!(x >= 'A' && x <='Z')
question
Assume that x is a char variable that has been declared and already given a value . Write an expression whose value is true if and only if x is NOT a letter.
answer
!((x >= 'A' && x <='Z') || (x >= 'a' && x <='z'))
question

answer
s > "mortgage" && s < "mortuary"
question
