First off, please put your code inside tags -- It is in the rules!!!!!!

#include <iostream>
#include <string>

int main()
{
int p;
A=0;
int j;
int R; 
int D;
int I;
int A;
int M;
int P;
int j;

cout << "enter cost of stereo purchase \n";
cin >> p;
cout<< "enter Rate of interest per month \n ";
cin>>R;
cout<<"enter period or Time \n";
cin >> T;
cout << "enter monthly payment\n";
cin >> D;
do
{ 
I=(P*R*T)/100;
A=I;
A=A+I;
M=P-I;
P=P-M;
j=j+1
}while(P>=D);

cout<<"the monthsit will take you to pay off the loan is " << j << endl;
cout<<"the Amout of intrest of intrest paid over the life of loan is" << A << endl;

getch();
system ("pause"); 
return EXIT_SUCSESS;
}

Your code is rather messy, this should work although I haven't compiled it.

@dangutdavid and Phil++ :

Both of you need to understand your basics well because without it you cant code anything.

Error 1 : Line 7 : Initializing A even before declaring it.
Error 2 : Line 38 : getch() ???

And please tell me that this program has no logic,the do while loop is a complete mess.

A=I;
A=A+I;

=> A=2*I or I+I and nothing else.

M=P-I;
P=P-M;

=>M=P-I
=>P=P-M=>P-(P-I)=>I

==>M=P-I
==>P=I

j=j+1
j was initially uninitialised hence it would be garbage + 1.
