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
