## Compound Interest Formula

Amount=P(1+r/100)t

P=Principal Amount
r=Rate of Interest
t=Time Periods.

## Program to Find Compound Interest Using C Programming

``````#include<stdio.h>
#include<math.h>
int main()
{
int principal_amount,rate_of_interest,Interest_applied,time_periods;
printf("\n\n\tProgram to Find Compound Interest Using C Programming.");
printf("\n\tEnter Principal Amount.");
scanf("%d",&principal_amount);
printf("\n\tEnter Rate of Interest.");
scanf("%d",&rate_of_interest);
printf("\n\tEnter Time Periods.");
scanf("%d",&time_periods);
float compond_interest=principal_amount*pow((1+(rate_of_interest/100)),time_periods);
printf("\n\tCompound Interest is: %lf\n\n\n",compond_interest);
return 0;
}``````

### Output

```Program to Find Compound Interest Using C Programming.
Enter Principal Amount.2000

Enter Rate of Interest.2

Enter Time Periods.3

Compound Interest is: 2000.000000
```

### Code Explanation

First, ask the user to input Principal Amount, Rate of Interest, Time Period.

Store the input values to variables using `scanf()` function.

In the program using the formula compound interest is calculated and stored in compound interest variable.

Print the output.
