write a program to find solution of ordinary differential equation using Euler's method in c++.

CODE:

#include<iostream.h>

#include<conio.h>

float f(float x,float y)

{

return (x*y);

}

void main()

{

clrscr();

int i;

float x,y,xn,h;

cout<<"Enter value of x:";

cin>>x;

cout<<"Enter value of y:";

cin>>y;

cout<<"Enter value of xn:";

cin>>xn;

cout<<"Enter size of interval:";

cin>>h;

cout<<"Euler's method:\n";

cout<<"x \t y"<<endl;

cout<<x<<" \t "<<y<<endl;

while(x<xn)
