There are pros and cons to using special characters in email subject lines. Generally, marketers report higher open rates.
Some report better engagement, but many don’t.
There are also reports of special characters causing problems with deliverability, mostly because spammers became very fond of special characters for a while.
Answer:
False
Explanation:
The private member of a class is not accessible by using the Dot notation ,however the private member are those which are not accessible inside the class they are accessible outside the class .The public member are accessible inside the class so they are accessible by using the dot operator .
<u>Following are the example is given below in C++ Language </u>
#include<iostream> // header file
using namespace std;
class Rectangle
{
private:
double r; // private member
public:
double area()
{ return 3.14*r*r;
}
};
int main()
{
Rectangle r1;// creating the object
r1.r = 3.5;
double t= r1.area(); // calling
cout<<" Area is:"<<t;
return 0;
}
Output:
compile time error is generated
<u>The correct program to access the private member of class is given below </u>
#include<iostream> // header file
using namespace std;
class Rectangle
{
private:
double r; // private member
public:
double area()
{
r1=r;
double t2=3.14*r2*r2;
return(t2); // return the value
}
};
int main()
{
Rectangle r1;// creating the object
r1.r = 1.5;
double t= r1.area(); // calling
cout<<" Area is:"<<t;
return 0;
}
Therefore the given statement is False

Answer:
Make every attempt to recover the data
Explanation:
If your decide to format the drive, use system restore or reinstall the windows OS you may end up loosing all your data so the best option is to try as much as you can attempting to recover the data because the data might or definitely will be lost while using other options you think are available.
Answer:
// here is code in C++.
#include <bits/stdc++.h>
using namespace std;
// function to compute sum and product
void square(int input)
{
// variable to store the square of number
long long squ_num;
calculate the square of number
squ_num=pow(input,2);
// print the output
cout<<"square of "<< input<<" is: "<<squ_num<<endl;
}
// driver function
int main()
{
int n;
// read the number until user enter 0
do{
cout<<"enter a number!! (0 to stop):";
// read the input from user
cin>>n;
// call the function to calculate square of input number
square(n);
}while(n!=0);
return 0;
}
Explanation:
Declare a variable "n" to read the input number from user.Call the function square() with parameter "n".In this function, it will calculate the square of the input number and print it.This will repeat until user enter 0 as input.Program will ends when user give 0 as input.
Output:
enter a number!! (0 to stop):5
square of 5 is: 25
enter a number!! (0 to stop):7
square of 7 is: 49
enter a number!! (0 to stop):11
square of 11 is: 121
enter a number!! (0 to stop):0
