For the following code, which statement is TRUE?

class Point      

{          

   private:

      double y;   

      double z;

   public:

      double x;   

};

Given

       const int SIZE = 50;

       int numbers[SIZE];

       int smallest;

write the code needed to find the smallest value in the array and output it using a cout statement.

4.

Define the following arrays

empNums

100-element array of ints

payRates

25-element   array of floats

miles

14-element array of   longs

cityName

26-element   array of strings

lightYears

1000-element array of   doubles

Given a partially filled array

       int array[MAX_COUNT];

where MAX_COUNT = 100 and int arrayCount = 25 (number of actual elements added)

write the code to output only the populated elements in the array.

                                                                

A. Exchanges values until they are all sorted B. Moves items immediately to their final position in the array C. Examines each element until a match is found D. Uses the same sort and search algorithms as arrays E. Starts in the middle of a sorted array

Explanation / Answer

1.)

----->a) vector<char> vecChar;

2.)

---->F) a, b, c and d are all false

3.)

const int SIZE = 50;

int numbers[SIZE];

int smallest;

/*****code is as follows**********/

int i;

smallest=numbers[0];

for(i=0;i<SIZE;i++)

if(smallest>numbers[i])

smallest=numbers[i];

cout<<"The smallest number is : "<<smallest;

4.)

A-------------->Bubble

B-------------->Selection sort

C-------------->Linear Search

D-------------->Vector

E-------------->Binary Search

5.)

suppose class name is A

method to be declared outside is : function

then syntax must be

void A::function(parameters)

{

}

i.e.

return_type class_name::method_name(parameters)

{

//body

}

6.)

int empNums[100];

float payRates[25];

long miles[14];

string cityName[26];

double lightYears[1000];

7.)

int i;

for(i=0;i<arrayCount;i++)

cout<<array[i];
