Question

22. Following the declaration double ptr you must assign to ptr a. b. c. a variable of type double. the address of a variable of a floating-point type. the address of a variable of type double. 23. Given the declarations void func(double pl, double p2): double x - 1.1,y -2.2 you can call the function funcO using a. func(x, y b. funcx, y) c. func(&x;, &y;) 24. In the equation x _ y % z, y and z are both int. Variable x is a double, y-34, and z- 6. What will be the value of the variable x? a. x = 4.0000000000 b, x = 5.0000000000 c, x = 5.6666666667 25. Which if statement would be true if you needed to see if x (an int) is greater than 26? a. if (x>0&&x;

Explanation / Answer

answers:

22)c.the address of a variable of type double.

Explanations:

pointer holds the address of the variable.

The data type is double (double *ptr), it holds the address of the variable of data type double.

eg) double *ptr;

double x;

ptr = &x;

23)c. func(&x,&y);

Explantion:

address of the variable are passed to the functions. it access the address of the funcitons.

eg)

main(){

double x=1.1, y=2.2;

func(&x,&y); //address is passed

}

void func(double* p1,double* p2) //pointer points the address

{

}

24)a. x=4.000000000

Explanation:

x = y % z ;

since 34 % 6 = 4

and x is a double data type variable, prints as 4.00000000

25) d. if(x>26)

it checks whether varible x is greater than 26,

if it is greater than 26, it goes into the loop

26)b. ||

{> ,== , != } are relational operators. It defines the relation between two varibles

where || is a logical operator.

27)If the question is from c++

then the answer is a.True

ex:

string str("my string");

cout<<" The length of string is :" << str.size();

output:

The length of string is :9

//for any explantion , please do comments
