Decision Control Statement In C Programming - " Ifelse and elseif "

If Else :

We can use “else” with “if” but it is up to us that will we use or not.The way to use else with is as below:

If(expression)

        statement  1;

else

        statement 2;

If the value of “if” expression become true than statement 1 will be execute otherwise statement 2 will execute.

Watch the program carefully :

                                                                    #include<stdio.h>

                                                                    #include<conio.h>

                                                                     main()

                                                                     {

                                                                     int numb;

                                                                     printf("Enter How Much Money do You Have? : ");

                                                                     scanf("%d",&numb);

                                                                     if(numb>50)

                                                                     printf("You are rich");

                                                                     else

                                                                     printf("You are poor");

                                                                     getch();

                                                                     }

Program Analysis:

Here two simple statement and condition are working that if the entered  number  become grater than 50,First statement will excuete otherwise if the number remain under 50 second statement will be published.

Elseif:

We can create “if else if” chain through else if in C Program.The structure is as following:

                                                          If(expression 1)

                                                                   Statement 1;

                                                          Else

                                                                  If(expression 2)

                                                                   Statement 2;

                                                           Else

                                                                   Statement3;
