 C Program to print the first N even numbers in reverse order.      In this example, we will print the first N even numbers in reverse order. Here N is the total number of even numbers you want to print. PROGRAM TO PRINT THE FIRST N EVEN NUMBERS IN REVERSE ORDER: #include <stdio.h> #include <conio.h> int   main () {      int   even , n , i ;      printf ( "Enter the value of N : " );      scanf ( " %d " ,& n );      printf ( "Printing first  %d  even numbers in reverse order : " , n );      for ( i = n * 2 ; i > 2 ; i --)     {          if ( i % 2 == 0 )         {              printf ( " %d \t " , i );  ...

 C program to Print the Digits of a Number in Words.      In this example, we will print the digits of a number in words.  For example, if a number 841 is entered through the keyboard  then the program must print “Eight Four One". For solving this first we have to reverse the number than by using switch statement we willl print the digits of the number in words.    PROGRAM TO PRINT THE DIGITS OF A NUMBER IN WORDS #include <stdio.h> #include <conio.h> void   main () {      int   n , num = 0 ;      printf ( "Enter the Number : " );      scanf ( " %d " ,& n );      while ( n != 0 )     {          num =( num * 10 )+( n % 10 );          n /= 10 ;     }      printf ( "Printing the...

 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 find Mean and Standard deviation(SD) for a set of n numbers using array.     In this example, we will calculate the mean and standard deviation for a set of n numbers entered by the user using array.    PROGRAM TO FIND THE MEAN AND STANDARD DEVIATION(SD) FOR A SET OF N NUMBERS USING ARRAY. #include <stdio.h> #include <math.h> #include <conio.h> void   main () {      int   n , i ;      float   x [ 50 ], mean , sd , sum ;      printf ( "How many numbers you want to enter : " );      scanf ( " %d " ,& n );      printf ( "Enter the numbers " );      for ( i = 0 ; i < n ; i ++)      {          scanf ( " %f " ,& x [ i ]);     }      f...

  C Program to Calculate the Factorial of a number using Function.     In this example, we will calculate the factorial of a number using function. Here we have used functions with Arguments and return value to perform this operation. We have declared a user-defined function fact which is called in the main function when printing the result. What is a Factorial of  a Number?      The factorial of a number is the product of all positive integers less than, equal to n. Factorial is denoted by the symbol '!'. Formula of factorial is n!=n x (n-1)! For example: 6!= 6 x 5 x 4 x 3 x 2 x1    = 720 PROGRAM TO CALCULATE THE FACTORIAL OF A NUMBER USING FUNCTION #include <stdio.h> #include <conio.h> int   fact ( int ); void   main () {      int   n ;      printf ( "Enter the number : " );      scanf ( " %d " ,& n );   ...

 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 ...
