Question 1
Q1 Part A
Write sections of a program
(1) to set up a dynamic array of strings to hold student names doing a certain course. 4 (2) to set up a dynamic array of student identity numbers for the corresponding student names delivered in (Q1 section A (1) ) 4
(3) to include a function called readInStudentName s to read a set of student names using the array set up in (Q1 section A (1) ) 5
(4) to include a function readInStudentIDNumbers to read in a set of student identity numbers referring to the array set up in (Q1 section A (2)). 4
(5) to include a function to printOutStudentNameAnd StudentIdNumber to write out all students details for those present in the arrays set up in Q1( section A (1) & (2)) 5
Part A 22 Marks
Q1 Part B
- Use the details from (Q1 Section A (1) ) to call the function readInStudentNames in (Q1 Section A (3) ). 3
- Use the details in Q1 (Section A (2) ) to call the function in readInStudentIdNumbers as listed in Q1( section A (4) ). 3 3. Print out the student details: name followed by student Id Number calling function printOutStudentNameAnd StudentIDNumber in (Q1 section A (5)) 4
Part B 10 Marks
Question 2 – Strings
Q2 Part A
i) Identify the error in the following code and provide and alternative correct solution:
int main() { char str1[] = "Hello"; char str2 [5]; str2 = str1; cout << str2; return 0; 5 }
ii) What is the outcome of the following code
char name[50]=”John”; char surname[50]=”Smith”; strcat (name, surname); strcat (surname, name); cout << name << endl; cout << surname << endl; 5
Part A 10 Marks
Q2 Part B
Write a program which detects whether a string is a palindrome or not. A palindrome is a word which is unchanged when the order of the letters is reversed. For example:
navan is a palindrome because the reverse is also navan
kayak is a palindrome because the reverse is also kayak
The program should prompt for a read a string input by the user. The program should then detect if this string is a palindrome or not.
Part B 20 Marks
Question 2 Total 30 Marks
Question 3 – Pointers
Q3 Part A
i) What does the reference operator (&) in C++ do?
ii) When using a pointer to reference a C++ data structure (struct) what operator do you use to access the members of the struct?
iii) Assume the variable declarations:
int Foo = 0;
int *ptr = &Foo;
Identify all of the following statements which will change the value of Foo to 1 -note there may be more than one correct choice:
ptr++; 3) (*Foo)++;
Foo++; 4) (*ptr)++;
iv) If a variable is a pointer to an integer, then which of the following operators is used to access the integer value pointed to by the memory address stored in the pointer?
‘.’ 3) ‘*’
‘&’ 4) ‘->’
v) Briefly explain one benefit that can be gained from using pointers.
Part A 10 Marks ( 2 marks each)
Q3 Part B
What is the outcome of executing the following code:
int main () { char ac[] = {'c', 'h','a','r','\0'}; char * str = ac; cout << *str; char c = str[3]; cout << c; str[1]= ‘l’; ac[3]=’p’; cout << ac; return 0;
}
Part B 5 marks
Question 4 - Random Access and Sequential Files
- what is a binary file? Give an example! 4
- what does fixed length record mean? 2
- Create a fixed length for a student holding student number, name, address & phone number and date of registration. 7
- Are cstring or string libraries used to set up fixed length strings? What is the advantage to for setting up fixed length records? Explain the advantage to the type of library for setting up random access files 7
- Explain how to set up random access files, including setting up a blank file inserting an additional record deleting a record 10
