No capital letter in void:

void powerArgs(int *parmA, int *parmB)
{
int temp = *parmA;
*parmA = *parmB;
*parmB = temp;
}

The code you posted is C, not C++.

/* Reset the original values after we print the result */// printf("%d raised to the %d power is %.0lf\n",parmA,parmB,*powerArgs(&parmA, &parmB));

Sorry, but your version of powerArgs() doesn't raise paramA to the power of paramB. Nor does it return anything so you can't put it in a printf() statement like that.
