C Program to find out the biggest of three numbers using Nested if Statement.

 C Program to find out the biggest of three numbers using Nested if Statement.


In this example we will learn how to find the biggest of three numbers using Nested if statement.


LOGIC OF THE BIGGEST OF THREE NUMBERS:


  • At first we have declared three variables a,b and c and we have stored the numbers inputted by the user in this three variables.


  • Then we have to check if the value of a greater than b then it will check if a greater than c if it is greater then it will print the value of a is the biggest of the three numbers and if it is not greater than it will print c is the biggest of three numbers. If the value of a not greater than b then it will not execute the above statements 

  • Then it will move to the second statement that is else if and will check if b greater than a if it is true then it will check if b greater than c if it is true it will print the value of b is the biggest of the three numbers if not then it will print the value of c is the biggest of three numbers.   


PROGRAM:

#include<stdio.h>
#include<conio.h>
void main()
{
    int a,b,c;
    printf("Enter the three Numbers :");
    scanf("%d%d%d",&a,&b,&c);
    if(a>b)
    {
        if(a>c)
            printf("%d is the biggest of the three numbers.",a);
        else
            printf("%d is the biggest of the three numbers.",c);
    }
    else if(b>a)
    {
        if(b>c)
            printf("%d is the biggest of the three numbers.",b);
        else
            printf("%d is the biggest of the three numbers",c);
    }
    getch();
}



OUTPUT:

C Program to find out the biggest of three numbers using Nested if Statement.


NESTED IF STATEMENT:


Nested if Statement means that if/else statement inside the body of another if statement. 


  • The Syntax of nested if statement is:

         if(expression)

{

if(expression)

statement;

else

statement;

}

else

statement;


  • Example of nested if statement:

if(a<=b)

{

if(a<b)

printf("%d<%d\n",a,b);

else

printf("%d=%d\n",a,b);

}

else

printf("%d>%d\n",a,b);

Here, in this example we have checked if a<=b if this statement is true then we will check if a<b if this is also true it will print (a<b) otherwise it will print (a=b). Else if a<=b is not true then it will print (a>b).

C Program to Add Two Matrices Using Multi-dimensional Array.

C Program to Add Two Matrices Using Multi-dimensional Array.       In this example, we will add two matrices using multi-dimensional array. Two matrices can be added if they are equal means their order/dimensions must be same. Addition of matrices is performed by adding the corresponding elements of the two matrices.     Here in the Output we have  allowed the user to enter the row and column size of their matrices according to their requirements but they can enter the value of row size and column size less than 100. PROGRAM #include <stdio.h> #include <conio.h> int   main () {      int   row , column , i , j , a [ 100 ][ 100 ], b [ 100 ][ 100 ], c [ 100 ][ 100 ];      printf ( "Enter the row size of the matrices(max. value 100) : " );      scanf ( " %d " ,& row );      printf ( "Enter the co...

C Program to find the sum of the elements of a 2-D array.

 C Program to find the sum of the elements of a 2-D array.     In this example, we will find the sum of the elements of a 2-D array allowing the user to enter the row size and column size according to their requiremnts.      Here in the output we have entered a row  size 3 and column size 3. PROGRAM #include <stdio.h> #include <conio.h> void   main () {      int   a [ 50 ][ 50 ], r , c , i , j , sum = 0 ;      printf ( "Enter the row size and column size of the array :" );      scanf ( " %d%d " ,& r ,& c );      printf ( "Enter the elements of the array : " );      for ( i = 0 ; i < r ; i ++)     {          for ( j = 0 ; j < c ; j ++)       ...

C Program to find out the roots of a Quadratic Equation and also test for Real and Complex roots

 C Program to find out the roots of a Quadratic Equation  and also test for Real and Complex roots.       In this example, we will calculate the roots of the quadratic equation by testing for real and complex roots. We can test real and complex roots by checking these conditions : If b 2  −4 ac  < 0, then there are no real roots. If b 2  −4 ac  = 0, then both the roots are equal. If b 2  −4 ac  > 0, then roots are real and distinct.   PROGRAM TO FIND OUT THE ROOTS OF A QUADRATIC EQUATION. #include <stdio.h> #include <conio.h> #include <math.h> int   main () {      int   a , b , c , d ;      float   x , y ;      printf ( "Enter coefficient of x^2,x and constant : " );      scanf ( " %d   %d   %d " ,& a ,& b ,& c );      d = b * b ...

C Program to input Values in a 2x2 square matrix and display the value

 C Program to input Values in a 2x2 square matrix and display the value     In this example, we will accept values from the user in a 2x2 square and matrix and then it is displayed. To solve this problem we must know what is matrices and arrays. What are Arrays?      An array is a data structure for storing more than one data member of similar data type.          Array can be of following types: One-dimensional Array Two-dimensional Array Multi-dimensional Array             In Array we must always initialize values. PROGRAM #include <stdio.h> #include <conio.h> int   main () {      int   a [ 2 ][ 2 ], i , j ;      printf ( "Enter the values of the matrix:" );      for ( i = 0 ; i < 2 ; i ++)     {          for ( j = 0 ; j < 2 ...

C Program to input and display details of students using structure

 C Program to input and display details of students using structure.       In this example, we will enter the details of students like roll number, name and total marks using structure and will be displayed. The total number of student should be entered according to the requirements of the user(maximum value is 50). We can increase the maximum number by changing the statement struct student[50];  to struct student[100];     Here in the output we have entered details of four student and displayed them accordingly. PROGRAM #include <stdio.h> #include <conio.h> struct   student {      int   roll ;      char   name [ 20 ];      int   total ; }; void   main () {      int   i , n ;      struct   student   std [ 50 ];      printf ( "Enter the number of students ...
