Simple Example Program For If..Else : Example 2

Definition

IF conditional statement is a feature of this programming language which perform different computations or actions depending on whether a programmer-specified boolean condition evaluates to true or false. Apart from the case of branch predication, this is always achieved by selectively altering the control flow based on some condition.

Syntax

	if (expression) {
		doSomething();
	}
	else	{
		doSomethingElse();
	}

Syntax Example

for example, In c
	if (i == 3) {
		doSomething();
	}
	else	{
		doSomethingElse();
	}

Syntax Explanation

Consider above example syntax,if (i == 3) 

  • which means the variable i contains a number that is equal to 3, the statements following the doSomething() block will be executed.
  • Otherwise variable contains a number that is not equal to 3, else block doSomethingElse() will be executed.

Example Program for If Else : Voting Check Example : 2

Example Program For If ... Else Example : 2
/* Example program to check whether the given age is eligible for vote or not */
// Header Files
#include<stdio.h>
#include<conio.h>

//Main Function
int main()
{
	// Declaring the variable age
	int age;

	// Reading the age
	printf("Enter your age:");
	scanf("%d",&age);

	// Checking the condition with If-Else statement
	if(age>=18)
	{
		// Printing the output if the condition is true
		printf("You are eligible for vote");
	}
	else
	{
		// Printing the output if the condition is fails
		printf("You are not eligible for vote");
	}

	// Output screen waits until get a character
	getch();

	// Returning to the main function
	return 0;
}

Sample Output:

Enter your age:25
You are eligible for vote

Enter your age:15
You are not eligible for vote
