Question

12 (03.02 lc)
a programmer is writing a program using ap exam pseudocode to calculate the modulus of two numbers. the programmer has written the following procedure.
procedure findmod(a, b)
{
mod ← a mod b
return mod
}
firstnumber ← 10
secondnumber ← 2
which of the following is the correct way to call the procedure to find the modulus of two numbers? (5 points)
○ modulus ← findmod(a mod b)
○ modulus ← procedure findmod(10, 2)
○ modulus ← findmod(a, b)
○ modulus ← findmod(firstnumber, secondnumber)

Explanation:

1. The procedure findMod(a, b) takes two input parameters a and b to compute their modulus.
2. The variables firstNumber (set to 10) and secondNumber (set to 2) hold the values we want to compute the modulus of.
3. A valid procedure call must pass the two values as arguments matching the procedure's parameter structure, without redefining the procedure or using invalid syntax in the call. The correct call passes the pre-defined variables to the procedure and assigns the result to modulus.

Answer:

modulus ← findMod(firstNumber, secondNumber)
