Understanding fclose


int fclose ( FILE * stream );

Close file
Closes the file associated with the stream and disassociates it.
All internal buffers associated with the stream are flushed: the content of any unwritten buffer is written and the content of any unread buffer is discarded.
Even if the call fails, the stream passed as parameter will no longer be associated with the file.



Parameters

 stream
Pointer to a FILE object that specifies the stream to be closed.

Return Value

 If the stream is successfully closed, a zero value is returned.
On failure, EOF is returned.

Example

/* fclose example */
#include <stdio.h>
int main ()
{
  FILE * pFile;
  pFile = fopen ("myfile.txt","wt");
  fprintf (pFile, "fclose example");
  fclose (pFile);
  return 0;
}

Putimage function in c

putimage function outputs a bit image onto the screen. Declaration:- void putimage(int left, int top, void *ptr, int op); putimage puts the bit image previously saved with getimage back onto the screen, with the upper left corner of the image placed at (left, top). ptr points to the area in memory where the source image is stored. The op argument specifies a operator that controls how the color for each destination pixel on screen is computed, based on pixel already on screen and the corresponding source pixel in memory. c smiling face animation This animation using c draws a smiling face which appears at random position on screen. See output below the code, it will help you in understanding the code easily. C programming code #include<graphics.h> #include<conio.h> #include<stdlib.h>   main() { int gd = DETECT, gm, area, temp1, temp2, left = 25, top = 75; void *p;   initgraph(&gd,&gm,"C:\\TC\\BGI");   setcolor(YELLOW);
