True or False The single statement cin alpha beta cin alp

True or False? The single statement cin >> alpha >> beta; cin >> alpha; cin >> beta; True or False? Assuming no input errors, an execution of the >> operator leaves the reading marker at the character immediately following the last data item read. True or False? The >> operator skips leading whitespace characters when looking for the next data value in the input stream. Which of the following is a valid input statement? cin >> student Age; cin cin; student Age alpha >> input Char >> beta; \' \' (blank) \'A\' \'.\' (period) \'4\' none of the above Which of the following is not one of the things a programmer must do in order to use files in a C++ program? Use a preprocessor directive to include the header file f stream. Declare each file stream in a variable declaration. Prepare each file for reading or writing by calling the open function. Specify the name of the file stream in each input or output statement that uses it. Erase the contents of each output file before running the program.

Solution

24)
   True

   We can break multiple variables while taking input over
   multiple cin statement

25)
   True

   Last read character will be in input buffer. You need to clear it

26)
   True

   >> reads till first white space

27)
   A) cin >> studentAge

28)
   Ans: C

   because 123 will be assigned in alpha, after that \'.\'
   in inputChar

29)
   E) Erase the content of each output file before rennuing the program, because while writing, C++ erase all content by default
