Q.3.(10 points) We know that when an array is defined a constant pointer is created which stores the starting address of an array. For example
float arr[6]={10,20,30,40,50,60};
a constant pointer, with the name of ‘arr’, is created as given below:[7]
arr+3 and *(arr+3)
If the type of the above-mentioned array is an integer instead of float then calculate arr+3 and *(arr+3)

- Placing function prototypes in the definitions of other functions restricts function calls to the function in which the prototypes appear.
[True] [False]
- Pointers are valid operands in arithmetic expressions, assignment expressions, and comparison expressions. However, not all the operators normally used in these expressions are valid in conjunction with pointer variables.
[True] [False]
- A pointer to void can be dereferenced just like any other pointer, by using the indirection operator (*).
[True] [False]
- If b is the name of an array of at least 4 elements, then the following statements both refer to its 4th element.
&b[ 3 ] bPtr +3
[True] [False]
- The following statement defines an array of pointers to strings.
const char *suit[ 3 ] = { “Hearts”, “Diamonds”, “Clubs” };

bool {sPrime (int num);
Q#4: Implement the following function threeToZero which accepts an integer array and its size, if there is a 2 in the array immediately followed by a 3, set the 3 element to 0.
Note: Indent your code properly. Use meaningful variable names. Write cin, cout, and all c++ keywords in lowercase (like if, for etc.)
void threeToZero(int arr{], int size)
{
// complete the function definition here
Part-III Give Long Answers, Each question carries equal marks. (30)
Q#1: Write down a program that accepts the following command line arguments:
- The name of the text file that contains single ~ digit integer data separated by a white space.
- An integer to be searched from the data in the file.
The program displays the total number of occurrences of the integer in the file data.
Q#2: Assume yourself as a part of the control unit of Windows Live hotmail. Your job is to determine the password length of the user entered passwords.
A password
- Is said to be short if it contains less than 6 characters.
- Is perfect if it its length is greater than 6. (Max. length is 20 characters.)
You are to design a function that takes a parameter string (By Reference) and determines its length according to the above mentioned criteria.
