Thewhileloop is abandoned when a false read is encountered. The content of
the second file namedipow.ccis:

/*--------------------------------------------

function ipow computes the integer powerij

--------------------------------------------*/

int ipow(int i, int j)

{

int k, accum=1;

for (k=1; k<=j; k++)

{

accum = accum * i;

};

return accum;

}

The content of the header fileipow.his:

#ifndef IPOWH

#define IPOWH

using namespace std;

int ipow (int, int);

#endif

Note that the declaration:

int ipow (int, int)
