A buffer overflow is when a piece of code writes more data to a buffer than the buffer is allocated to hold.
This code segment is susceptible to a buffer overflow because the gets() function does not check how much data is being read in, and it is possible to write more data than what the 50 byte buffer can hold. This can lead to undefined behavior.
Importance of buffer overflow:A buffer overflow can lead to undefined behavior, which can cause a program to crash or even allow an attacker to take control of the program.

What is Equilibrium?
A situation where opposing forces or actions are evenly distributed and neither is stronger than the other. Both the supply and the demand were equal.
When the size of the decrease in demand is greater than the increase in supply, the quantity decreases.According to the Graph (a), the leftward shift in the demand curve—caused by a greater demand for new chips—is greater than the forward shift in the supply curve. As a result, the amount decreases.When the size of the demand decline is smaller than the supply growth, the quantity increases.According to the Graph (b), there is a greater forward shift in the supply curve than a greater backward shift in the demand curve, which causes the equilibrium quantity to increase.Given that there is a rise in supply and a decline in demand, the price will decrease in both scenarios.
