solution:
#include<graphics.h>
#include<conio.h>
void main()
{
int gd=DETECT,gm;
initgraph(&gd,&gm,"C:\\TURBOC3\\BGI");
circle(180,180,50);
}

2D transformation for reflection in C program (Computer Graphics).

Program: #include<stdio.h> #include<conio.h> #include<graphics.h> #include<stdlib.h> void refx(int x1,int x2,int x3,int y1,int y2,int y3){ line(320,0,320,430); line(0,240,640,240); x1=(320-x1)+320; x2=(320-x2)+320; x3=(320-x3)+320; line(x1,y1,x2,y2); line(x2,y2,x3,y3); line(x3,y3,x1,y1); } void refy(int x1,int x2,int x3,int y1,int y2,int y3){ line(320,0,320,430); line(0,240,640,240); y1=(240-y1)+240; y2=(240-y2)+240; y3=(240-y3)+240; line(x1,y1,x2,y2); line(x2,y2,x3,y3); line(x3,y3,x1,y1); } void main() { int gd=DETECT,gm; int x1,y1,x2,y2,x3,y3; clrscr(); initgraph(&gd,&gm,"c://turboc3//bgi"); line(320,0,320,430); line(0,240,640,240); x1=150;y1=100; x2=220;y2=220; x3=220;y3=110; line(x1,y1,x2,y2); line(x2,y2,x3,y3); line(x3,y3,x1,y1); getch(); refx(x1,x2,x3,y1,y2,y3); getch(); refy(x1,x2,x3,y1,y2,y3); getch(); closegraph(); }

2D transformation for Rotation in C programming (Computer Graphics).

Program: #include <math.h> #include<stdio.h> #include <conio.h> #include <graphics.h> void main() { int gd=DETECT,gm,x1,x2,y1,y2,x4,y4; float angle=0.0,ang; initgraph(&gd,&gm,"C:\\turboc3\\BGI"); printf("Enter Co-ordinates:"); scanf("%d%d%d%d",&x1,&y1,&x2,&y2); line(x1,y1,x2,y2); printf("Enter the angle:"); scanf("%f",&ang); angle=(ang*3.14)/180; x4=x2-(((x2-x1)*cos(angle))-((y2-y1)*sin(angle))); y4=y2-(((x2-x1)*sin(angle))+((y2-y1)*cos(angle))); line(x2,y2,x4,y4); getch(); closegraph(); }

Write a C program for binary search in sorted array.

Solution: #include <stdio.h> int main() { int c, first, last, middle, n, search, array[100]; printf("Enter number of elements\n"); scanf("%d",&n); printf("Enter %d integers\n", n); for (c = 0; c < n; c++) { scanf("%d",&array[c]); } printf("Enter value to find\n"); scanf("%d", &search); first = 0; last = n - 1; middle = (first+last)/2; while (first <= last) { if (array[middle] < search) { first = middle + 1; } else if (array[middle] == search) { printf("%d found at location %d.\n", search, middle); break; } else last = middle - 1; // printf("%d\n"...
