Write a C program to find the roots of a quadratic equation.
#include<stdio.h> #include<conio.h> #include<math.h> void main() { float a,b,c,d,r1,r2,imp,rp; clrscr(); printf(“Enter a,b,c:”); scanf(“%f%f%f”,&a,&b,&c);

#include<stdio.h> #include<conio.h> main() { int i,j,n; printf("\n enter how many lines"); scanf("%d",&n); for(i=1;i<=n;i++)
The total distance travelled by vehicle in 't' seconds is given by distance = ut+1/2at^2 where 'u' and 'a' are the initial velocity (m/sec.) and acceleration (m/sec2).
Write C program to find the distance travelled at regular intervals of time given the values 'u' and 'a'.
The program should provide the flexibility to the user to select his own time intervals and repeat the calculations for different values of 'u' and 'a'.
#include<stdio.h> main() { int a,u,t,t1,t2,i; float s; clrscr(); printf("ENTER THE VALUES OF a,u,t,t1,t2:");

Scaling
It is used to alter or change the size of objects. The change is done using scaling factors. There are two scaling factors, i.e. Sx in x direction Sy in y-direction. If the original position is x and y. Scaling factors are Sx and Sy then the value of coordinates after scaling will be x1 and y1.
Translation
It is the straight line movement of an object from one position to another is called Translation. Here the object is positioned from one coordinate location to another.
