##### C Program For Compound Interest

Here’s a C program that calculates the compound interest based on the principal amount, rate of interest, time period, and compounding frequency:

```				```
#include <stdio.h>
#include <math.h>

int main() {
// Declare variables
float principal, rate, time, amount, compound_interest;

// Get input from user
printf("Enter principal amount: ");
scanf("%f", &principal);

printf("Enter rate of interest: ");
scanf("%f", &rate);

printf("Enter time in years: ");
scanf("%f", &time);

// Calculate amount
amount = principal * pow((1 + rate / 100), time);

// Calculate compound interest
compound_interest = amount - principal;

// Print compound interest
printf("Compound interest = %f\n", compound_interest);

return 0;
}

```
```
##### Output • This program first declares five variables: `principal`, `rate`, `time`, `amount`, and `compound_interest`. The `principal` variable stores the principal amount, the `rate` variable stores the rate of interest, the `time` variable stores the time in years, the `amount` variable stores the amount, and the `compound_interest` variable stores the compound interest.

• The program then gets input from the user for the principal amount, the rate of interest, and the time in years.

• The program then calculates the amount using the formula `amount = principal * pow((1 + rate / 100), time)`.

• The program then calculates the compound interest using the formula `compound_interest = amount - principal`.

• The program then prints the compound interest to the console.

• You can change the values of the variables in the program to calculate compound interest for different amounts, rates, and times. ```				```
SELECT AVG(emp_sal)
FROM employee;
```
```
```				```
SELECT COUNT(*)
FROM employee;
```
