C++ program to compute simple interest and compound interest.

 Q27. Write a program to compute simple interest and compound interest.

Ans.

#include<iostream.h>

#include<math.h>   //for pow()

#include<conio.h>  //for clrscr()

 

//Main Function

void main()

{

float principle,rate,time,n,SI,CI,f;

clrscr();   //for clear screen

 

cout<<“\n Enter Principle Amount: “;

cin>>principle;

cout<<“\n Enter Interest Rate: “;

cin>>rate;

cout<<“\n Enter Time Period in years: “;

cin>>time;

cout<<“\n Enter the number of periods: “;

cin>>n;

 

//SI=PRT/100

SI=((principle*rate*time)/100);

 

//CI=P[POW((1+R),N)-1]

rate=rate/100;

CI=(principle * ( (pow((1+rate),n)) -1));

 

cout<<“\n Simple Interest: Rs.”<<SI;

cout<<“\n Compound Interest: Rs.”<<CI;

 

getch();  //To hold output screen

}

//End of main()

 

Output:

Enter Principle Amount: 5000

Enter Interest Rate: 5

Enter Time Period in years: 10

Enter the number of periods: 12

 

Simple Interest: Rs.2500

Compound Interest: Rs.3979.281738
