Invalid

Explanation / Answer

Question 1
It is invalid as the function name is not provided.

Question 2
It is valid function heading as function prototype is there function name is there and then parameter list is there.

Question 3-
it is 10^2 = 100

Question 4-
the annswer will be
1.0+2.0-12.0 which will be equal to -0.9 it is because the * as more priority then +,-

Question 5-
it is a valid function heading without a parameter list.

Question 6-
it will be 2 because sqrt(5-1)=> sqrt(4) which is 2.

Question 7-
it will be 2.121 as sqrt(7.5-5.0+2.0)=> sqrt(4.5)= 2.121

Question 8-
fabs(7.5-5.0)=it will be 2.5 as fabs calculate the absolute value.
