HERE'S THE PROGRAM, IT WORKS PERFECTLY ON MY COMPILER!!

BUT JUST ADJUST THE SPACINGS, THE PROBLEM'S DUE TO THIS EDITOR.....

#include<iostream.h>

#include<math.h>

void simple_int ( );

void comp_int ( );

void factorial ( ); /* Function prototypes */

void prime ( );

void main ( )

{

int ch;

char yn;

do

{

   cout<<"\n\n MENU \n"; /* Displaying Menu */

   cout<<"\n 1. Simple Interest ";

   cout<<"\n 2. Compound Interest ";

   cout<<"\n 3. Factorial ";

   cout<<"\n 4. Prime no. ";

   cout<<"\n\n\t Enter ur choice ... ";

   cin>>ch;

   switch (ch)

{

   case 1: simple_int ( ); break;

   case 2: comp_int ( ); break;

   case 3: factorial ( ); break;

   case 4: prime ( ); break;

   default: cout<<"\n Invalid choice!! "; break;

}

cout<<"\n\n\n Continue (y/n)?? ... ";

cin>>yn;

}

while ( (yn=='y')||(yn=='Y') );

/* end of do-while loop and main */

}

void simple_int ( )

{

float p, r, t, si;

cout<<"\n\n Enter Principal in Rs. ";

cin>>p;

cout<<"\n Enter time in years ";

cin>>t;

cout<<"\n Enter rate per year ";

cin>>r;

si = p*r*t/100; /* Calculating Simple Interest */

cout<<"\n\n The Simple Interest is Rs. "<<si;

}

void comp_int ( )

{

float p, r, ci;

int t;

cout<<"\n\n Enter Principal in Rs. ";

cin>>p;

cout<<"\n Enter time in years ";

cin>>t;

cout<<"\n Enter rate per year ";

cin>>r;

ci = p* pow(( 1 + r/100 ), t);

/* Calculating Compound Interest */

cout<<"\n\n The Compound Interest is Rs. "<<ci;

}

void factorial ( )

{

int f = 1;

int i, n;

cout<<"\n\n Enter the no.whose factorial is 2 b found \n";

cin>>n;

for (i=1; i<=n; i++)

f = f*i; /* Finding the factorial */

cout<<"\n\n "<<n<<" ! = "<<f;

}

void prime ( )

{

int c, i, n;

c = 0;

cout<<"\n\n Enter the number ";

cin>>n;

for (i=1; i<=n; i++)

{

if ( n%i == 0 )

c++; /* Checking 4 any divisors */

}

if ( c==2 )

cout<<"\n "<<n<<" is a prime number. ";

else

cout<<"\n "<<n<<" is not a prime number. ";

}

RATE !!
