Understanding P13 Programming Set of Multiple Choice Questions

• Question 1. To declare a function to check an array is increasing or not we use the following statement:
  • void CheckAsc (int a [], int n);
  • int CheckAsc (int * a, intn);
  • long CheckAsc (int * S);
  • double CheckAsc (int S [], intn);
• Question 2. Which code will permutate 2 numbers a and b:

  • t = a; a = b; b = t;

  • t = a; a = b; t = b;
  • a = t; b = a; t = b;
  • t = b; b = a; a = t;
• Question 3. In the following sentences, which sentence is correct:

  • The value of a variable can be changed.

  • The value of a variable cannot be changed.
  • It is possible to declare two variables with the same name in the same function.
  • Cannot declare 2 variables with the same name in the same function.
• Question 4. Symbols that characterize the impact on data are called:
  • Operator
  • Expression.
  • Jaw
  • Turn
• Question 5. The size of the pointer variable is:
  • 1 byte.

  • 2 bytes

  • 3 bytes.
  • There is no right answer
• Question 6. Indicate the value of the expression: 2 + 4> 2 && 4 <2;
  • first
  • -first
  • 0
  • There is no right answer
• Question 7. What is the logical value of the following expression:! (1 && 1 || 1 && 0);
  • first
  • 0
  • -first
  • There is no right value
• Question 8. Select the expression representing num as the number between 1 and 9 but it must be 4:
  • num> 1 && num
  • num> 1 || num

  • num> = 1 && num <= 9 && num! = 4;

  • No sentence is correct
• Question 9. Find the results of the following program:

  {
  
  int n;
  
  for (n = 18; n> 0; n/= 2)
  
  printf ('% 3d', n);
  
  };

  • '18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 '.
  • '18 9 4 2 1 '.
  • '18 9 4 2 1 0 '.
  • No answer right
• Question 10. Find the results of the following program:

  #include
  
  main ()
  
  {
  
  int i, ch;
  
  for (i = 0, ch = 'A'; i <5; i ++, ch ++) putchar (ch);
  
  };

  • 'ABCDE'.
  • 'ABC'.
  • 'ACEG'.
  • No answer right
• Question 11. Find the results of the following program:

  #include
  
  main ()
  
  {
  
  int i, ch;
  
  for (i = 0, ch = 'A'; i <4; i ++, ch + = 2) putchar (ch);
  
  };

  • 'ABCDE'.
  • 'ABC'.
  • 1. 'ACEG'.
  • No answer right
• Question 12. Which of the following is correct if the declaration is made:

  char * ptr;
  
  char msg [10]; char v;

  • ptr = v;
  • ptr = msg;
  • Both sentences are true
  • No sentence correctly
• Question 13. Why are the functions scanf () and printf () called 2 import and export functions in the format:
  • Because they have a format string in the parameter.
  • They are often used to import and export values in a predetermined style.
  • The above two functions are not two formatted export functions.
  • Another reason
• Question 14. Which of the following functions belongs to unformatted import functions:

  printf ();
  
  scanf (); getchar (); putchar ();

  • 1 and 2
  • 3 and 4
  • 1 and 4
  • 2 and 3
• Question 15. If strcmp (S1, S2) returns a negative integer, then:
  • The content of S1 series is larger than the content of the S2 series.
  • Chain content S1 is smaller than the content of series S2.
  • The content of chain S1 is equal to the content of chain S2.

  • Data entered is not properly formatted
