Question

in one way selection, if a semicolon is placed after the expression in a if statement, the expression in the if statement is it always true

Answer 1

this statement is false

because:

• Syntax of one-way (if) selection:

if (expression)
  statement1;
  statement2;

• if is reserved word
• expression must evaluate to true (nonzero) or false (0)
• statement1 executed if value of expression true
• statement1 bypassed if value false; program execution moves to statement2
• statement2 is executed regardless
