Celia is a potato peeler for CanCan Foods. She decides to quit her job and instead work as a seamstress at CoverUp Clothing. This would cause:
1.a movement along the production possibilities curve.
2.a movement towards a point that is outside the PPC
3.an outward shift of the production possibilities curve.
4.an inward shift of the production possibilities curve.
Consider a production possibilities curve with maize on the vertical axis and cars on the horisontal. Unusually good weather for growing maize shift:
1.neither the horisontal intercept nor the vertical intercept.
2.the horisontal intercept rightward and the vertical intercept upward.
3.the horisontal intercept rightward but does not shift the vertical intercept.
4.the vertical intercept upward but does not shift the horisontal intercept.
The market for drones has undergone some changes over the past two years.

Which of the following is the most likely explanation for these changes? Over the past two years:
1.demand has increased and supply has decreased.
2.both supply and demand have increased.
3.both supply and demand have decreased.
4.supply has increased and demand has decreased.

calculation to make the data secure.
Now the manager of the organization
asked his IT employee to make the
program which will function as follows:
a) * will subtract the numbers b) - will
divide the numbers c) / will add the
numbers d) + will multiply the numbers.
Use operator overloading.
Write a program to find if a year is a leap year or not. We generally assume that if a year number is divisible by 4 it is a leap year. But it is not the only case. A year is a leap year if −
1. It is evenly divisible by 100
2. If it is divisible by 100, then it should also be divisible by 400
3. Except this, all other years evenly divisible by 4 are leap years.
So the leap year algorithm is, given the year number Y,
● Check if Y is divisible by 4 but not 100, DISPLAY "leap year"
● Check if Y is divisible by 400, DISPLAY "leap year"
● Otherwise, DISPLAY "not leap year"
For this program you have to take the input, that is the year number from an input file input.txt that is provided to you. The input file contains multiple input year numbers. Use a while loop to input the year numbers from the input file one at a time and check if that year is a leap year or not. Your output should go in the console.
