Fantastic C programs

1.  Program

#include

#include

void main ()

{

int a, b;

int c;

float f;

  a = 10;

  b = 20;

 

  c = a + b;

  printf("value of c : %d \n", c);

  f = 70.0/3.0;

  printf("value of f : %f \n", f);

  return 0;

  getch();

}

Output

value of c : 30

value of f : 23.333334

2. Program

#include 

#include 

#define length 10   

#define width  5

#define newline '\n'

void main()

{

   int area;  

   area = length * width;

   printf("value of area : %d", area);

   printf("%c", newline);

   return 0;

   getch();

}

Output

               value of area : 50

3. Program

#include 

#include 

void func(void);

static int count = 5; 

void main()

{

   while(count--)

   {

      func();

   }

   return 0;

}

void func( void )

{

   static int i = 5; 

   i++;

   printf("i is %d and count is %d\n", i, count);

   getch();

}

Output

i is 6 and count is 4

i is 7 and count is 3

i is 8 and count is 2

i is 9 and count is 1

i is 10 and count is 0
