if-else statement

if-else statement :

                                This statement contains a single condition with two different blocks of statements. The flowchart and the syntax of “ if-else “ statement is shown below :

                

Syntax:      if(condition)

                                     {

                                                true statement-1;

                                     }

                                     else

                                     {

                                                false statement-2;

                                     }

                                     Statement-3;

                In this if-else statement, first the condition will be checked. If the condition is true then the true statement-1 will be executed and after that statement-3 will be executed. But if the condition is false then the false statement-2 will be executed and then the statement-3 will be executed.

Ex:          #include<stdio.h>

                #include<conio.h>

                void main()

                {

                      int a,b,max;

                      clrscr();

                      printf(“Enter the values of a and b:”);

                      scanf(“%d%d”,&a,&b);

                      if(a>b)

                      {

                                max=a;

                      }

                      else

                       {

                                max=b;

                       }

                       printf(“\n Maximum value is :%d”,max);

                       getch();

                }
