Test on C Programming P4

This article presents Test on C Programming P4 in a clear, structured format. It helps readers review key concepts, test their understanding, and learn from the material.

Understanding Test on C Programming P4

• Question 1: Character data included
  • Digit digits
  • Alphabetic characters '% ld'
  • Special characters
  • All answers above
• Question 2: Function used to allocate dynamic memory for dynamic memory type defined by programmers such as (union, struct):
  • calloc ()
  • malloc ()
  • realloc ()
  • All 3 plans on
• struct S1 * next;} * head; Know the pointer '* head' stores the address of the first element in the list. Which of the following statement groups adds an element to the top of the list:
  • p-> next = head; head = p
  • p-> next = head; head-> p; head = p-> next.
  • head-> next = p; p = head;
  • No sentence correctly
• struct S1 * next;} * head; Know the pointer '* head' stores the address of the first element in the list. Which of the following statement groups deletes the first element from the list:
  • head-> next = head;
  • head = head-> next-> next;
  • head = head-> next;
• Question 5: What is the wrong statement when talking about linked list:
  • Each element in the linked list must have at least one field used to store the address.
  • Using linked lists usually saves more memory than using arrays.
  • Using linked lists often costs more memory than arrays.
  • No idea right
• Question 6: Which sentence does not mention the advantages of using the structure:
  • You can mix up data types in a unit
  • You can store data of different length characters in a structure variable.
  • Data can be stored in a module and in a hierarchical form.
  • At least one memory is required for the same data.
• Question 7: How can I represent the 'hoten' element of SV1:

  struct SV
  
  {
  
  hoten char [20];
  
  } SV1, * p;
  
  p = & SV1;

  • SV1.hoten;
  • p-> hoten;
  • & hoten;
  • Answers a and b
• Question 8: Where is the wrong statement:
  • You can pass a parameter as a struct variable to the function.
  • Can pass parameters as a pointer variable to the function.
  • Can pass a parameter as a pointer variable struct to the function.
  • Cannot pass parameters as elements of struct for functions.
• Question 9: Let array A contain elements of type struct, which statement is true when accessing the fields of the elements:
  • A [indicator]. School name;
  • A. field name;
  • & A. school name;
  • & A [indicator]. School name;
• Question 10: The memory space used to store the nodes of the double linked list:
  • Storage scattered in memory
  • Always store continuously in memory
  • Stored storage
  • Store segmented style
