[3/3]Calculation of Marks using Logical Operators.

The most efficient of the three programs. Solves all the problems arising out of the usage of if else and else if statements.


The marks obtained by a student in 5 different subjects are input through the keyboard.
The student gets a division as per the following rules:

Percentage above or equal to 60 - First Division
Percentage between 50 and 59 -- Second Division
Percentage between 40 and 49 --- Third Division
Percentage less than 40 ---- Fail

Write a program to calculate the division obtained by the student.




#include<stdio.h>
main()
{

int m1, m2, m3, m4, m5, per;

printf ("Enter marks in five subjects");
scanf ("%d %d %d %d %d", &m1, &m2, &m3, &m4, &m5);


per = (m1+m2+m3+m4+m5)/ 5 ;

if (per>=60)
printf ("First Division");

if ((per>=50) && (per<60))

printf ("Second Division");

if ((per>=40) && (per<50))

printf ("Third Division");

if (per<40)

printf ("Fail");

}

C Program - Calculation of Area and Circumference of a Circle using Pointers

The following program is one good example that illustrates how we can return more than one value in a function. The answer is certainly using Pointers. The following program demonstrates the method. Write a function that calculates both Area and Perimeter/ Circumference of the Circle, whose Radius is entered through the keyboard. #include <stdio.h> main ( ) { int radius ; float area , perimeter ; printf ( " \n Enter radius of a circle:" ) ; scanf ( "%d" , & radius ) ; areaperi ( radius , & area , & perimeter ) ; printf ( "Area=%f" , area ) ; printf ( " \n Perimeter=%f" , perimeter ) ; } areaperi ( int r , float * a , float * p ) { * a = 3.14 * r * r ; * p = 2 * 3.14 * r ; } // This Program exhibits the use of Call By Reference .

Matchstick Game using C Programming

Write a program for a matchstick game being played between the computer and a user. Your program should ensure that the computer always wins. Rules for the game are as follows: -There are 21 matchsticks. -The computer asks the player to pick 1, 2, 3 or 4 matchsticks. -After the person picks, the computer does its picking. -Whoever is forced to pick up the last matchstick loses the game. -There are 21 matchsticks. -Whoever is forced to pick up the last matchstick loses the game. So the last one is special, so it's all about how to get rid of 20 matches in pairs of turns. -The computer asks the player to pick 1, 2, 3 or 4 matchsticks. So if we reduce the total by 5 each round, the sequence will go 21 16 11 6 1 In effect, whatever number the user picks (n), the computer picks 5-n #include <stdio.h> main ( ) { int matchsticks = 21 , user , computer ; printf ( "Do not enter Invalid Numbers. \n Numbers above 4 are invalid." ) ; printf ( " \n If you do so, t

Generation of Fibonacci Sequence using Recursion.

Write a recursive function to obtain the first 25 numbers of a Fibonacci sequence. In a Fibonacci sequence the sum of two successive terms gives the third term. Following are the first few terms of the Fibonacci sequence: 1 1 2 3 5 8 13 21 34 55 89 ... #include <stdio.h> main ( ) { static int prev_number = 0 , number = 1 ; // static : so value is not lost int fibonacci ( int prev_number , int number ) ; printf ( "Following are the first 25 Numbers of the Fibonacci Series: \n " ) ; printf ( "1 " ) ; // to avoid complexity fibonacci ( prev_number , number ) ; } fibonacci ( int prev_number , int number ) { static int i = 1 ; // i is not 0 , cuz 1 is already counted in main . int fibo ; if ( i = = 25 ) { printf ( " \n done" ) ; // stop after 25 numbers } else { fibo = prev_number + number ; prev_number = number ; // important steps number = fibo ; printf ( " \n %d" , fibo ) ; i + + ; // increment
