12. Write a program to demonstrate Euler's Method.

          
        /* Program to execte Euler's Method*/
	#include<stdio.h>
	#include<conio.h>
	#include<math.h>
	float dif ( float x,float y )
	{
	    return x+y;
	}
	void main()
	{
	    float x  ,h,x0,x1,y0,y1;
	    printf("Enter the values of x,h,x0,y0: ");
	    scanf("%f%f%f%f", &x, &h, &x0,&y0);
	    x1=x0;
	    y1=y0;
	    while(x1 < x) {
	        y1 += h*dif(x1,y1);
	        x1 += h;
	        printf("\n Values of y=%f, when x=%f",y1,x1);
	    }
	    getch();
	}
