Nested if in C Language

Hello friends how are you, today in this blog i will teach you what is nested if statement, syntax of nested if , how nested if statement works and many programs using nested if statement in a very simple way.

Let's start

👉Syntax

1.Nested means one inside another so one if inside another if is called nested if.

2.In the case of if in the place of condition always zero and non-zero value is checked in which zero means condition false and non-zero means condition true

👉Example 1 

#include<stdio.h>
int main()
{
//Assigning value to the variable
int x=10;
if(x>5)//true
{
  if(x<5)//false
     {
     printf("Hello");
     }
  printf("Hi");
}
}
/*
### output ###
Hi
*/

👉Example 2

#include<stdio.h>
int main()
{
//Assigning value to the variable
int x=10;
if(x>5)//true
{
  if(x>5)//true
     {
     printf("Hello");
     }
  printf("Hi");
}
}
/*
### output ###
HelloHi
*/

👉Example 3 

#include<stdio.h>
int main()
{
//Assigning value to the variable
int x=10;
if(x<5)//false
{
  if(x>5)//true
     {
     printf("Hello");
     }
  printf("Hi");
}
}
/*
### output ###
No output because outer if condition is false
*/

👉Example 4: Find greatest value in three number

#include<stdio.h>
int main()
{
 //variables declaration
 int no1,no2,no3;
 //taking user input
 printf("Enter first number\n");
 scanf("%d",&no1);
 printf("Enter second number\n");
 scanf("%d",&no2);
 printf("Enter third number\n");
 scanf("%d",&no3);
 //applying condition
 if(no1>no2)
 {
 	if(no1>no3)
 	{
 		printf("%d is greatest",no1);
 	}
 }
  if(no2>no1)
 {
 	if(no2>no3)
 	{
 		printf("%d is greatest",no2);
 	}
 }
  if(no3>no1)
 {
 	if(no3>no2)
 	{
 		printf("%d is greatest",no3);
 	}
 }
}
/*
###Output###
Enter first number
85
Enter second number
96
Enter third number
47
96 is greatest
*/
