Question

program. 13. What's the output of the following program? #include< iostream> #include&math> using namespace std; int p 7; void main) extern double var int p abs(-90); system( "pause"); double var = 55; 14. How many times does "#" print? forlint i 0;j< 10; +ti) if(i-2141 6) continue; cout<< "#"; 15. Write the function declaration/prototype for a, pow function b floor function 16. State True or False a. b. c. d. e. isupper function returns a double value for loop is a post-test loop An else is paired with the most recent if that has not been paired with any other else. In Ctt, bool variables can be used to store the value of a logical expression. Executing a continue statement in the body of a loop skips the loop's remaining statements and proceeds with the next iteration

Answer 1

13)

The output is 7(::p) + 90 (p) - 5.5(var) = 91.5

14)

7 times

from 0-9 there are 10 numbers out of which # will not be printed for 2,4,6 hence # will be printed for 10-3 = 7 numbers.

15)

a. double pow(double x,double y)

The pow() function takes ‘double’ as the arguments and returns a ‘double’ value.

b. T floor(T x) where T can be double,float,long double.

The floor() function takes a single argument and returns a value of type double, float or long double type.

16)

a. False, isupper retruns an int value

b. False, for loop is pre-test loop(test expression is evaluated before running the body of the loop) whereas do-while loop is a post-test loop(test expression is evaluated after executing the body of the loop)

c. False

Consider the following:
if(var < 100)

{

if(var <50)

{

cout << "Less than 50" << endl;

}

}

else

{

cout << "Greater than 100" << endl;

}

In this else is paird with if(var < 100) and not with if(var < 50).

d. True, bool stores either true or false.

e. True
