Answer the following statements true (T) or false (F)

1) The following are all valid variable names: _under_bar_, m928134, t5, j7, her_sales,
his_account_total, a, b, c, z, z2.
2) The statement cout << "a = 5;"; is a typical example of an assignment statement.
3) A valid arithmetic expression with no parentheses is evaluated from left to right.
4) The following are all invalid variable names: 3g, 87, 67h2, h22, 2h.
5) By convention, function names begin with a capital letter and all subsequent words in
the name begin with a capital letter.

1) True.
2) False. The statement is an output statement. The text a = 5; is output to the screen.
3) False. Arithmetic operators can appear in any order in an expression, so the expression is a = b+ c* d; actually evaluates from right to left because of the rules of operator precedence.
4) False. h22 is a valid variable name. The others are invalid because they each begin with a digit.
5) False. Function names begin with a lowercase letter and all subsequent words in the name begin with a capital letter.
