## Calculate Simple Interest in C++

```#include<iostream.h>
#include<conio.h>

void main()
{
float amount, rate, time, si;

clrscr();
cout<<"Enter Principal Amount: ";

cout<<"Enter Rate of Interest: ";
cin>>rate;

cout<<"Enter Period of Time: ";
cin>>time;

si = (amount * rate * time) / 100;
cout<<"Simple Interest: "<<si;

getch();
}
```

## Output 1

```Enter Principal Amount: 3000
Enter Rate of Interest: 2
Enter Period of Time: 3

Simple Interest: 180
```

```Enter Principal Amount: 1000
Enter Rate of Interest: 2
