In C++, the natural logarithm function log ( ) can be accessed through the header file <cmath> ; which makes log ( ) function a :

• Pre-defined function

• User-defined function

• Standard library function

• None of the them

• All of them

How many parameters are declared in the following statement which contains the declaration of a function?

int Test (int x, double y, float z, char p, n)

*Type only the number as answer*

What shall be the output of the program?

• 82

  54.67

  34.833

• 82.503

  54.67

  27.833

• 81

  54.67

  27.833

• 89.503

  54.67

  34.833

• 82

  54.67 27.833

Differentiate between variable declaration and function declaration using an example.

The argument passed by "value" to a function can be :

• a variable

• a constant

• an expression

• all of them

int module (int, int&);

int main()

{ int a = 80, b = 129, c = 144;

module(a, c);

cout << "a = " << a << ", b = " << c; }

int module (int x, int& y)

{ y = x; }

Choose the correct program output.

• a = 80

  b = 80

• a = 80, b = 129

• a = 80

  b = 144

• a = 80, b = 80

• a = 80, c = 144

Choose the correct program output.

• 6

• bool

• returns 7

• 7
