float P, Rpct, R, M;

R = Rpct/100;
M = P * R * pow(1+R, N)/(12 * ( pow(1+R, N)-1));
printf ("\n$%1.2f, @%11.2F%% costs $%1.2f over %i years", P,Rpct,M,N);
printf ("\nPayments will total $%1.2F", 12*M*N);
//after input the data and then enter, i want to see the actual result, but the program terminate immediately. getchar(); does not help in this case.
what should i do?
