Modify this code for question:

#include <stdio.h>

#include <math.h>

int main(void)

{

FILE * fileout;

int ix,iy,it,Nt;

double newV[31][21],V[31][21],x,dx,y,dy;

fileout=fopen(“buckbeak.dat”,”w”);

printf(“nEnter number of iterations “);

scanf(“%d”,&Nt);

dx=0.10;

dy=0.10;

for(iy=0; iy<21; iy=iy+1)

{

for(ix=0; ix<31; ix=ix+1)

{

V[ix][iy]=0.0;

}

}

iy=20;

for (ix=0;ix<31; ix=ix+1)

   {

   }

for (it=0; it<Nt;it=it+1)

{

for(iy=1; iy<20;iy=iy+1)

{

for(ix=1;ix<30; ix=ix+1)

{

newV[ix][iy]=0.25*(V[ix+1][iy]+V[ix-1][iy]+V[ix][iy+1]+V[ix][iy-1]);

}
