State the following is true or false. If false, explain why."Empty parentheses following a function name in a function definition indicate that the function does not require any parameters to perform its task."

Please fill in the blanks for the following statements: The ________________ statement passes a value back to a function’s caller.

- in this exercise, please do not include and use string class. The function is using only array notation and manipulation.- string functions such as strlen is not allowed.- it should not have multiple return statements in the same function- there should be no global variable.- the function should not traverse the arrays more than once (e.g. looping through the array once only) A C++ PROGRAM named "changeCase" that takes an array of characters terminating by NULL character (C-string) and a boolean flag of toUpper. If the toUpper flag is true, it will go through the array and convert all lowercase characters to uppercase. Otherwise, it will convert all uppercase to lowercase. For example, if the array is {'H', 'e', 'l', 'l', 'o', '\0'} and the flag is true, then the array will become{'H', 'E', 'L', 'L', 'O', '\0'}. And if the flag is false, the array will become{'h', 'e', 'l', 'l', 'o', '\0'}

2. If a function have all the default arguments but still some values are passed to the function then _________.

What is wrong with this function ?

-Convert SES variable to a factor and assign the value labels “low”, ”middle” and “high” to the 3 levels of thevariable. Then -Define the variables complic, comorb, depressi, diabetes as factors.

State whether each of the following is true or false. If false, explain why h) All arguments following the format control string in a printf function must be preceded by an ampersand (&).
