Fibonacci Series C Programming

C Program to Display same Source Code as Output

#include

#include 

int main()

{

   FILE *fp;

   char ch;

   fp = fopen(__FILE__, "r");

   do

  {

      ch = getc(fp);

      putchar(ch);

   }

   while (ch != EOF);

   fclose(fp);

   return 0;

}

Output

#include

#include

int main()

 {

   FILE *fp;

   char ch;

   fp = fopen(__FILE__, "r");

   do

     {

      ch = getc(fp);

      putchar(ch);

      }

    while (ch != EOF);

   fclose(fp);

   return 0;

}

C Program to Add two Numbers Using Function in C Programming

#include

#include

int main()

{

   int num1, num2, res;

   printf("\nEnter the two numbers : ");

   scanf("%d %d", &num1, &num2);

   res = sum(num1, num2);

   printf("\nAddition of two number is : ");

   return (0);

}

int sum(int num1, int num2)

{

   int num3;

   num3 = num1 + num2;

   return (num3);

}

Output

Enter the two numbers : 12 15

Addition of two number is : 27

To Display of message using function in C Programming

#include

#include

void main()

{

message();

}

void message()

{

printf("Hi, How are you? ");

}

Output

         

         Hi, How are you?

C Program to generate the Fibonacci Series starting from any two numbers

#include

#include 

int main()

{

   int first, second, sum, num, counter = 0;

   printf("Enter the term : ");

   scanf("%d", &num);

   printf("\nEnter First Number : ");

   scanf("%d", &first);

   printf("\nEnter Second Number : ");

   scanf("%d", &second);

    printf("\nFibonacci Series : %d  %d  ", first, second);

    while (counter < num)

     {

      sum = first + second;

      printf("%d  ", sum);

      first = second;

      second = sum;

      counter++;

   }

    return (0);

}

Output

Enter the term : 5

Enter First Number : 1

Enter Second Number : 3

Fibonacci Series : 1 3 4 7 11 18 29
