Concept explainers
a)
Pass-by-value:
A copy of the argument’s value which is passed into the parameter variable is referred as pass by value. In the pass by value, the called method creates new variables to store the value of the arguments passed to it. The changes made in the formal parameters do not reflect on the actual parameters.
Example:
changeVal(int num);
Here, “changeVal” is the method name and the “num” is the argument passed by value.
b)
Pass-by-value:
A copy of the argument’s value which is passed into the parameter variable is referred as pass by value. In the pass by value, the called method creates new variables to store the value of the arguments passed to it. The changes made in the formal parameters do not reflect on the actual parameters.
Example:
changeVal(int num);
Here, “changeVal” is the method name and the “num” is the argument passed by value.

- What is the output of following code.arrow_forwardMODIFY THE CODE BELOW try..arrow_forward[Fish Tank] You play with a clown fish that has an initial size so. The fish can eat other fish in a tank organized in m columns and n rows. The fish at column i and row j has a positive size si,j. When your fish eats another fish, it grows by that amount. For example, if your clown fish has a size of 10 and eats a fish of size 5, it becomes of size 15. You cannot eat a fish that is bigger than your size. The game starts by eating any fish in the first (left-most) column that is not bigger than yours. After that, you advance one column at a time by moving right. You have only three allowed moves. You either stay at the same row, move one row higher or one row lower. You will always move to the right. Thus, you will make exactly m moves to advance from left to right. Your goal is to exit the fish tank from the right with the biggest possible size. The figure below shows an example with the best answer highlighted. In this case, the final fish size is 71 (10+8+7+24+22). You are required…arrow_forward
- This Code print the first occurrences of x, Please Modify the code to print the last occurrences of x and print how many times it exists? ( with explanation for each line if possible) many thanks.arrow_forwardquestion- what is the output of the following output?arrow_forwardCode in python: A certain company has encoded the accounts of its customers and requires that you provide an algorithm that, given an account code, informs if it is valid according to the following description: The account codes are made up of 4 digits counted from right to left, plus the verification digit. The verifying digit is obtained by adding the digits of the account number of the even positions and multiplying the digits of the odd positions, from the new result the residue of the division is extracted for 10, which represents the verifying digit. Develop the code in python as a check digit class that returns 1 if it is correct or 0 if not Heading: Extract digits, verifier calculation, Account verification, Integral algorithmarrow_forward
