Understanding Set of Multiple Choice Questions About Programming with P17 Prize

• Question 1. What does the following statement mean:

  FILE * fopen (tep1, 'r +');

  • Open the allowable text file
  • Open the readable text file
  • Open the text file to allow both read and write.
  • Open an existing text file to read
• Question 2. What does the following statement mean:

  int open (tep1, O_TRUNC);

  • Open the binary file to write
  • Delete the contents of the file
  • Open the text file to read and write
  • All the answers above
• Question 3. The component's structure can be accessed through the pointer as (with p being the structure pointer, a is the structure component):
  • (* p).a;
  • * p-> a;
  • 1 and 2 wrong
  • 1 and 2 are correct
• Question 4. Which statement is invalid in the following declaration:

  float y;} t, * p, a [10];

  • p = & t;
  • p = & t.x;
  • p = & a [5];
  • p = & a;
• Question 5. Please choose the best sentence:

  struct immediately {int ng, th, n;} vaotruong, ratruong; typedef struct sinhvien {char hoten; ngay ngaysinh;}; immediately ngayinh;};

  • No assignment: vaotruong = ratruong;
  • 'sinhvien' is the structure name, 'vaotruong', 'ratruong' is the structure variable name.
  • You can write 'vaotruong.ng', 'ratruong.th', 'sinhvien.vaotruong.n' to access the corresponding components.
  • 1, 2, 3 right
• Question 6. In value initializations for the following structures, select the correct sentence:

  struct S1 {int immediately, ladder, male;}; S1 = (2, 1, 3);
  
  struct S2 {char hoten [10]; struct S1 ngaysinh;}; struct S1 ngaysinh;}; S2 = {'Cups', {4, 5, 6}};

  • S1 correct
  • S2 is correct
  • Both S1 and S2 are correct
  • Both S1 and S2 are wrong
• Question 7. For structured types, which of the following is not allowed:
  • Assign variables to each other
  • Assign two array elements (structure type) to each other.
  • Assign an array element (structure type) to a variable or vice versa.
  • Assign two structured arrays with the same number of elements.
• Question 8. Select the best sentence in the following sentences:

  struct {int big; float soluong;} x[10]; float soluong;} x [10];
  
  for (int i = 0; i <10; i ++) scanf ('% d% f', & x [i].to, & x [i].soluong);

  • The above program segment has a syntax error.
  • Addressing operators are not allowed for 'to' and 'soluong' components.
  • The address of the 'soluong' component leads to an improper operation.
  • All is wrong
• Question 9. To create a linked list, according to which of the following students is the correct declaration of the self-pointing structure to be used:

  Student 1:
  
  struct Sv * tiep;};
  
  Student 2:
  
  typedef
  
  struct SV node;
  
  node * tiep;};
  
  Student 3:
  
  typedef
  
  struct * tiep;} node;

  • first
  • 2
  • 2 and 3
  • All 3 declare above
• Question 10. To use the linked list, consider the following two statements (need 1KB to store information about a student):Declaration 1: struct SV {thongtin; struct SV *tiep;}; struct SV * tiep;}; Declaration 2: SV struct {thongtin}; struct DS *;;;; (With 'thongtin' is a data component of the structure); Choose the best sentence in the following sentences:
  • Declaration 1 takes more memory than declaring 2.
  • Declaration 2 will help the program run faster when changing positions 2 students.
  • Declaration 1 will help save the command more when writing the function to change the position of 2 students.
  • Declaration 2 will help the program run faster when browsing the list.
