Question

Follow the algorithm outlined and fill in the proper value in the blank.

Main function
{ call function compute_value (a, b)
Assign the return value to variable c
}
Function compute_value(u, v)
{
x=u+v
return x
}
If the value of a is 7 and value of b is 8, then the value of c is

A. 15
B. 56
C. 64
D.78

Answer 1

The value of variable 'c' after calling compute_value(7, 8) is 15, as it is the sum of the parameters passed to the function.

Step-by-step explanation:

If the value of a is 7 and the value of b is 8, then in the function compute_value(u, v), where u is assigned the value of a and v is assigned the value of b, the operations performed are x = u + v. Substituting the given values, we get x = 7 + 8, which equals 15. Hence, the value assigned to variable c in the main function after calling compute_value(a, b) is 15.

The value of c can be determined by following the algorithm outlined. In the main function, the compute_value(a, b) function is called and the return value is assigned to variable c. The compute_value(u, v) function calculates the sum of u and v and returns the result.

Since the value of a is 7 and the value of b is 8, we can substitute these values into the algorithm. Thus, the value of c is the sum of 7 and 8, which is 15. Therefore, the correct answer is A. 15.
