Comma ( , ): It is used to separate two variable declarations in same line.

                    Semicolon ( ; ): It is used to terminate a statement in C++.
                    Equal sign ( = ): It is used to assign a value to a variable.
                 Operators

                                                                                                          Operator
                 Operators  are  special  symbols  in  C++  that  are  used  to  perform
                 calculations. They are used along with operands or values to get the
                 desired result. For example:                                                  5  +  3

                 In the preceding example, 5 and 3 are the operands and + (plus) is an
                 operator. The plus operator is used to perform the addition operation.
                 Other operators are - (minus), * (multiply) and / (divide). We will learn
                                                                                             Operands

                 Program 2: To calculate the sum of two numbers.

                 #include<iostream.h>
                 #include<conio.h>

                 void main()
                 {
                     clrscr();

                     int a, b, sum;
                                                                DOSBox 0.74, Cpu speed: max 100% cycles, Frameskip 0, program:   TC
                     a = 10;                                 The sum of two numbers is:30_
                     b = 20;

                     sum = a + b;
                     cout<<"The sum of two numbers is:"<<sum;
                     getch();

                 }

                 Program 3: To swap the values of two variables without using third variable.

                 #include<iostream.h>
                 #include<conio.h>

                 void main()
                 {
                     clrscr();
                     int a, b;
                     a = 15;
                     b = 25;

                      cout<< "Values of a and b before swapping are " << a << " and " <<
                      b << ".\n";
