    Select True or False: 1.  Data items in a class may be public. 2.  Class members are public by default. 3.  Friend functions have access only to public members of the class. 4.  A function designed as public can be accessible by non-members of a class. 5.  Friendship is commutative. 6.  new and delete are operators. 7.  We can implement generic classes using templates 8.  Using operator overloading we can invent new operators 9.  Inheritance helps in making a general class into a more specific class.) 10. Classes can be inherited privately. 11. Constructors can be virtual like virtual destructors   12. A class encapsulates the implementation and interface of a user-defined data type and constitutes an abstract data type. 13. std::cout is a standard input stream. 14. Preprocessor #define macro and inline functions use the same mechanism. 15. The new operator returns the address and size of the memory block that it allocates....

 Defining Variables variable_name = <variable data> num="1" name="Devil" Accessing variable Variable data could be accessed by appending the variable name with ‘$’ as follows: #!/bin/bash VAR_1="Devil" VAR_2="OWL" echo "$VAR_1$VAR_2" Unsetting Variables The unset command directs a shell to delete a variable and its stored data from list of variables. It can be used as follows: #!/bin/bash var1="Devil" var2=23 echo $var1 $var2 unset var1 echo $var1 $var2 Note: The unset command could not be used to unset read-only variables. Read only Variables. These variables are read only i.e., their values could not be modified later in the script. Following is an example: #!/bin/bash var1="Devil" var2=23 readonly var1 echo $var1 $var2 var1=23 echo $var1 $var2 Now let us see all the above codes in action together. Following is a shell script that includes all the shell variables discussed above # accessing the declared varia...

 Two types of decision-making statements are used within shell scripting. They are – If-else statement case-sac statement If-else statement If else statement is a conditional statement. It can be used to execute two different codes based on whether the given condition is satisfied or not. There are a couple of varieties present within the if-else statement.  They are – ==================== if-fi  Name="Girish" if [ "$Name" = "Girish" ]; then   echo "His name is Girish. It is true." fi ==================== if-else-fi  ==================== Age=17 if [ "$Age" -ge 18 ]; then     echo "You can vote" else     echo "You cannot vote"     fi ==================== if-elif-else-fi  ==================== Age=17 if [ "$Age" -ge 18 ]; then     echo "You can vote" elif [ "$Age" -eq 17 ]; then     echo "You can vote after one year" else     echo "You cannot vote"     fi ===============...

  Assignment 1 Q1. Write a menu driven program for Date in a C. Declare a structure Date having data members day, month, year. Implement the following functions. void initDate(struct Date* ptrDate); void printDateOnConsole(struct Date* ptrDate); void acceptDateFromConsole(struct Date* ptrDate); Q2.
