Exception Handling in C++ Programming Example (code)

Exceptions

Exceptions are the unexcepted outcomes that occur during the execution of the program that disturbs the program.

Types of Exceptions in C++

there are different types of exceptions in c++ some of them are given below.

• try-catch-throw
• multiple catches 
• multiple try blocks
•  catch-all 
• user-defined exceptions

User-defined Exceptions

the exception that is inherited from the exception header file and coded by the user according to his requirements are called user-defined exceptions.

Example code of the user-defined exception

Program(code) Example

#include<iostream>

#include<exception>

using namespace std;

class OverSpeed:public exception{

private:

int speed;

public:

const char *what()

{

return "Speed Is exceeds Then Limit";

}

void getSpeed()

{

cout<<"Speed of the Bike "<<speed<<endl;

}

  void setSpeed(int speed)

  {

   this->speed=speed;

  }

};

class HeavyBike{

private:

int speed;

public:

HeavyBike()

{

speed=0;

cout<<"Speed of the Bike"<<speed<<endl;

}

void acceleration()

{

for(;;)

{

speed+=10;

cout<<"Speed of bike is"<<speed<<endl;

if(speed>=300){

OverSpeed s;

s.setSpeed(speed);

throw s;

}

}

}

};

int main()

{

HeavyBike Mehran;

try{

Mehran.acceleration();

}catch(OverSpeed s)

{

cout<<s.what()<<endl;

s.getSpeed();

}

return 0;

}
