Final answer:
Array declarations a and g are valid. Declarations b, c, d, and f are invalid due to various errors such as incorrect type, unspecified size, syntax error, and case sensitivity. Declaration e is conditionally valid depending on context.
Step-by-step explanation:
I will determine whether the following array declarations are valid. If a declaration is invalid, I will explain why.
- a. int list[61]; - This declaration is valid. It declares an array named 'list' which can hold 61 integers.
- b. strings names[20]; - This declaration is invalid because 'strings' is not a valid type in many programming languages, the correct type should be 'string'.
- c. double gpa[ ]; - This declaration is invalid because the size of the array is not specified.
- d. double[-50] ratings[ ]; - This declaration is invalid; it seems like there's a syntax error with the placement of '[-50]', and also the size of the array is not declared.
- e. string flowers[35]; - Assuming 'string' is a valid type in the context, this declaration is valid. It declares an array named 'flowers' which can hold 35 strings.
- f. int SIZE = 10; double sales[2 * size]; - This declaration is invalid because 'size' should be capitalized as 'SIZE' to reference the variable correctly.
- g. int MAX_SIZE = 50; double sales[100-2 * MAX_SIZE]; - This declaration is valid. It declares an array named 'sales' which can hold 0 doubles (100 - 2*50 = 0).
