# Cube Root Program In C

Finding that a given number is even or odd, is a classic C program. We shall learn the use of conditional statement `if-else` in C.

## Algorithm

Algorithm of this program is very easy −

```START
Step 1 → Take integer variable A
Step 2 → Assign value to the variable
Step 3 → Perform A modulo 2 and check result if output is 0
Step 4 → If true print A is even
Step 5 → If false print A is odd
STOP
```

## Flow Diagram

We can draw a flow diagram for this program as given below −

## Pseudocode

```procedure even_odd()

IF (number modulo 2) equals to 0
PRINT number is even
ELSE
PRINT number is odd
END IF

end procedure
```

## Implementation

Implementation of this algorithm is given below −

```#include <stdio.h>

double cubeRoot(double n) {
double i, precision = 0.000001;

for(i = 1; (i*i*i) <= n; ++i);         //Integer part

for(--i; (i*i*i) < n; i += precision);  //Fractional part

return i;
}

int main() {
int n = 125;

printf("Cube root of %d = %lf", n, cubeRoot(n));

return 0;
}
```

## Output

Output of the program should be −

```Cube root of 125 = 5.000000
```
