Question text Determine whether the ff hypotheses about a computer program • There is an undeclared variable or there is a syntax error in the first five lines. • If there is a syntax error in the first five lines, then there is a missing semicolon or a variable name is misspelled. • There is not a missing semicolon. • There is not a misspelled variable name. lead to the conclusion • There is an undeclared variable. Let the following symbols represent the corresponding statements: uv - There is an undeclared variable. se - There is a syntax error in the first five lines. ms - There is a missing semicolon. vm - There is a misspelled variable name. Thus, in symbolic form, we have to show whether the argument below is valid: uv V se se → (ms V vm) ~ ms ~ VM ... uv
