for(j=0;j<=m;j++)
{ d1=d2;
a[j]=a[j]*i+d1;
d2=a[j]/10;
a[j]%=10;
if(d2>0&&j==m)
{
k=1;
while(d2>0)
{
a[j+k]=d2%10;
d2/=10;
k++;

NZEC error
Firstly, get your indentations in place. It is really hard to read your code.
Your code works fine on Ideone (doesn’t give any error).

Post your code in proper blocks, no offense, but its too ugly to read and interpret. You may like posting the ideone code.
