Answer / ram kumar
include the header file graphics.h
use the built in function rect(x1,y1,x2,y2)
such that (x1,y1) and (x2,y2) are the coordinates

int main(void)
{
/* request auto detection */
int gdriver = DETECT, gmode, errorcode;
int left, top, right, bottom;
/* initialize graphics and local variables */
initgraph(&gdriver, &gmode, "");
/* read result of initialization */
errorcode = graphresult();
if (errorcode != grOk) /* an error occurred */
{
printf("Graphics error: %s\n", grapherrormsg
(errorcode));
printf("Press any key to halt:");
getch();
exit(1); /* terminate with an error code */
}

main() { char a[4]="HELLO"; printf("%s",a); }
Write a program using one dimensional array to assign values and then display it on the screen. Use the formula a[i]=i*10 to assign value to an element.

Can you send Code for Run Length Encoding Of BMP Image in C Language in linux(i.e Compression and Decompression) ?
void main() { static int i=i++, j=j++, k=k++; printf(“i = %d j = %d k = %d”, i, j, k); }
main() { register int a=2; printf("Address of a = %d",&a); printf("Value of a = %d",a); }
#define prod(a,b) a*b main() { int x=3,y=4; printf("%d",prod(x+2,y-1)); }
main() { char *p="hai friends",*p1; p1=p; while(*p!='\0') ++*p++; printf("%s %s",p,p1); }
main() { char string[]="Hello World"; display(string); } void display(char *string) { printf("%s",string); }
3) Int Matrix of certain size was given, We had few valu= es in it like this. =97=97=97=97=97=97=97=97=97=97=97 1 = | 4 | | 5 | &= nbsp; | 45 =97=97=97=97=97=97=97=97=97=97=97 &n= bsp; | 3 | 3 | 5 | = | 4 =97=97=97=97=97=97=97=97=97=97=97 34 |&nbs= p; 3 | 3 | | 12 | &= nbsp; =97=97=97=97=97=97=97=97=97=97=97 3 | &nbs= p; | 3 | 4 | = | 3 =97=97=97=97=97=97=97=97=97=97=97 3 | = ; | | | = ; 3 | =97=97=97=97=97=97=97=97=97=97=97 &= nbsp; | | 4 | = ; | 4 | 3 We w= ere supposed to move back all the spaces in it at the end. Note: = If implemented this prog using recursion, would get higher preference.
What are the following notations of defining functions known as? i. int abc(int a,float b) { /* some code */ } ii. int abc(a,b) int a; float b; { /* some code*/ }
func(a,b) int a,b; { return( a= (a==b) ); } main() { int process(),func(); printf("The value of process is %d !\n ",process(func,3,6)); } process(pf,val1,val2) int (*pf) (); int val1,val2; { return((*pf) (val1,val2)); }
