1- The best choice for a data type used to store the grade to be recorded at the end of the term for this course would be a(n) ____________. Valid values would be A, B, C, D, or F, no A- or B+ would be permitted, instead a single value will be stored.
2-

3-The best choice for a data type used to store the cost of a pair of shoes would be in a(n) ____________. Hint: For your answer enter the default data type.
4-________ would be stored in x after the following statement (x++), assuming there was a compile time initialization of x defined as int x = 15;

Answer 1

Assuming the program language considered here is C++ or Java

Answers for all the questions are same in C++ and Java except for Question # 2

================================================================================

1. char (char always store a single letter or character)

============================================

In C++
2. string or char[] ( we can either use string or char array)

In Java

Its String

============================================
3. float (cost can be integer or float hence using float)

============================================
4. x will be 16 (after x++ value will be incremented by 1)

============================================
5. int sum = x+y; ( here we create a varaible of type int and store the sum of x an y to it)

============================================
6. int (we count things in integer, so the data type should be an int type)

============================================
