Explain basics of exceptional handling in oops.
Explain basics of exceptional handling in oops.
Exception handling in oops or c++ is a process to handle runtime errors. We perform exception handling so the normal flow the application can be maintain even after runtime error. In c++ or oops,exception is an even or object which is thrown at run time. It is a runtime error which can be handled. If we don't handle the exception, it prints exception message and terminate the program.
Exception handlings maintains the normal flow of the application. In such case,rest of code is executed even after exception
Write a program in c++ explaining the call by value and call by reference functions
Write a program in c++ explaining the call by value and call by reference functions
Call by value function: while calling a function,we passed the value of variable into the function.such functions are known as call by value.
For example:
Writing a c++ program to add two numbers
#include<iostream.h> //header file
void add(int,int); //declaration
void main()
{
int a,b;
cout<<"enter the values of a and b";
cin>>a>>b;
add(a,b);
}
void add(int x,int y)
{
int c;
c=x+y;
cout<<c;
}
Call by reference functions: while calling a function we instead of passing the value , we passed the address of variable.
For example:
#include<iostream.h>
void add(int*,int*);
void main()
{
int a,b;
cin>>a>>b;
add(&a,&b);
}
void add(int*x,int*y)
{
int c;
c=x+y;
cout<<c;
}
There are just example.

What are recursive functions? Give example
What are recursive functions? Give example
When a function call itself,it is called recursive functions.
For example: Recursive functions for factorial
#include<iostream.h>
int fact(int n)
{
if(n==0)
{
return 1;
}
else
{
return(n*fact(n-1));
}
}
int main()
{
int num;
cout<<"enter a positive integer";
cin>>num;
cout<<"The factorial of"<<num<<"is"<<fact(num);
return 0;
}
