What Is If-Else Statement In C Language?

Hello Programmers,

Today we will discuss the 'if-else' statement. In the last blog, we studied 'if' statement. These if-clauses are very important in c language. 

if-else statement: 

if-else statement is meant to perform one block of statement out of possible two blocks of statements depending on the result of a condition.

Syntax:

if(condition)

{

    Statement block-1;

}

else

{

    Statement block-2;

}

In upper syntax, the statement block -1 is executed when 'if' condition is true. If the condition is false then else block is executed then statement block-2 is executed.

Flow Chart:

The program which used if-else: 

#include<stdio.h>

#include<conio.h>

void main()

{

    int age;

   clrscr();

   printf("Enter your age");

   scanf("%d",&age);

   if(age>20)

    {

        printf("You are eligible for this game"  );

    }

  else

   {

        printf(" You are not eligible for this game");

    }

getch();

}

Output:

 

Run1: 

            Enter your age: 21

            You are eligible for this game 

Run2: 

            Enter your age: 19

            You are not eligible for this game
