IF-ELSE STATEMENT
If Statements
The if statement is used to conditionally execute a block of code based on whether a test condition is true. If the condition is true the block of code is executed, otherwise it is skipped.Syntax:
if(condition)
{
statement1;
statement1;
...........................1;
}
Example:#include <stdio.h>
main()
{
int number = 5;
int guess;
printf("I am thinking of a number between 1 and 10\n");
printf("Enter your guess, please \n");
scanf("%d",&guess);
if (guess == number)
{
printf("Incredible, you are correct\n");
}
}
if-else Statement
The else statement provides a way to execute one block of code if a condition is true, another if it is false.Syntax:
if(condition)
{
statement1;
statement1;
...........................1;
}
else
{
statement1;
statement1;
...........................1;
}
Program: WAP a program to find out the entered number is even or odd.#include<stdio.h>
#include<conio.h>
main()
{
int x;
printf("Enter any number");
scanf("%d", &x);
if(x%2==0
printf("Even No.";
else
printf("Odd No.");
getch();
}
Nested if-else Statement
The else statement provides a way to execute one block of code if a condition is true, another if it is false.Syntax:
if(condition)
{
statement1;
statement1;
...........................1;
}
else if(condition)
{
statement1;
statement1;
...........................1;
}
Example : finding out the greatest number among three numbers
