Answer:
The program to this question can be given as:
Program:
#include <iostream> //header file
using namespace std; //using name space.
int CountCharacters(char userChar,string userString) //define function.
{
int count = 0; //define variable
for (int i=0;i<userString.length();i++) //loop
if (userString[i]==userChar) //if block
count++; //increment the value.
return count; //return value.
}
int main() //main method.
{
string userString= "Clanguage"; //define variable and assign value.
char userChar = 'a'; //define variable and assign value.
cout << CountCharacters(userChar,userString); //calling function and print value.
return 0;
}
Output:

Answer:
the applicable design step will depend on the findings as to the cause(s) of the problem
Explanation:
First of all, the affected airplane(s) should be examined to find the proximate cause(s) of the indicator flashing. Once that is known, corrective action can be investigated.
If we assume the airplane has been manufactured and maintained in accordance with all released and approved procedures (a big assumption), then the next step might be to revisit the analysis that sets rigging position and limits--both for manufacturing and for maintenance. Attention should be given to all allowable tolerances anywhere in the linkage related to the gear position sensor, and to the sensor behavior in relation to gear position.

As an engineer responsible for landing gear indication, I have had to deal personally with this issue. A number of factors are involved, including landing gear linkage and its tolerances; sensor rigging and its tolerances; sensor target size, position, and the geometry of its travel in relation to the sensor. Temperature can also be a factor, affecting both the mechanical linkage and the sensor behavior.
Up/down and locked/unlocked sensors for each gear can contribute to the problem. Each has its own geometry, which is not always easy to discern from the multitude of design drawings and different engineering groups involved. Sensor vendors like to work with a specific target geometry and motion that may not be duplicated on the airplane, so sensor behavior is not always well-specified. The specification to the vendor may need to be revisited.
When sensors are located on moving parts, wire routing and protection come into play. In some cases, wiring may be "in the wind" when landing gear is extended, so must be protected against a variety of assaults. When things rub on wires, damage always occurs eventually. The nature and extent of the protection provided can also be something to assess in the investigation.
Maintenance and repair procedures can also be scrutinized. We have seen issues related to the way splices and crimps to wiring are done, and where those are allowed to be located. Deicing fluid is corrosive to wiring, and travels up a wire as though it were a straw. So, careful protection is needed for wire ends exposed to areas where deicing fluid may be found.
Sensors that rely on magnetic properties of materials can be affected by residual magnetism. Manufacturing and maintenance procedures that detect and/or eliminate those effects may need to be reassessed.
The airplanes I worked on did not have a computer between the position sensor and the indicator light. I have worked with indicators that were computer driven, and that did flash. In one case, the intermittent flashing problem took years to solve, and was eventually traced to a poor design choice in the way internal wiring was routed in the computer chassis. So, the design of both computer software and computer hardware may also need to be revisited.
In short, every part of the design process may need to be revisited.
The best practices used in the distribution layer involve the use of HSRP, GLBP, is:
The four best practices used in the distribution layer normally involve the use of certain functions and protocols. These practices ensure efficient and uninterrupted network operations. The most practical ones, from the provided options, would be: c. Using HSRP (Hot Standby Router Protocol), d. Using GLBP (Gateway Load Balancing Protocol), f. Using Layer 3 routing to the core, and g. Summarizing routes.
HSRP is a protocol that allows multiple routers to collaborate in presenting the illusion of a single virtual router to the hosts on the LAN. The inclusion of GLBP helps in balancing the load across a group of redundant routers. Using Layer 3 routing to the core is beneficial in order to maintain versatile connectivity and keep network segmentations to a minimum. Lastly, summarizing routes can minimize the size of the routing table and reduce the overhead on the router's resources.
The answer is:
"Use Layer 3 routing to the core (f)
Summarize routes (g)
Use HSRP (c) or GLBP (d)
Disable trunking in host ports (a)"

Answer:
The following are four best practices used in the distribution layer:
Use HSRP. This provides default gateway redundancy and ensures connectivity for end devices in case of a failure.
Use GLBP. This provides both default gateway redundancy and load balancing for optimal network performance and availability.
Use Layer 3 routing to the core. This eliminates the need for Spanning Tree Protocol (STP) and improves convergence and scalability.
Summarize routes. This reduces the size of the routing table and the amount of routing updates, which enhances network stability and efficiency.
These best practices are based on the Cisco Enterprise Campus Infrastructure document1 and the Cisco Press article on Hierarchical Network Design2.

Answer:
It depends upon the programming language that you are working on, and you can set your own error message using the try catch option. As an example, suppose you are working on the C#. Code like below can be added:
using System;
class MainClass {
static void Main(string[] args) {
int a = 5;
int b= 0;
int c= 100/2;
console.WriteLine(c);
try {
int d = a / b;
} catch (DivideByZeroException err) {
Console.WriteLine(err);
}
}
}
System.DivideByZeroException: Attempted to divide by zero.
This will give the above error message. And this is an error message by the system. We can also have a user-defined error message.
