# Write a C++ Program to find Cube Root of a Number

*Find Cube Root of a Number*

Write a C++ Program to find Cube Root of a Number. Here’s simple Program to find Cube Root of a Number using pow( ) function in C++ Programming Language.

To find **cube root** of any number we need to find 0.3 power of any number.* For example* : : if you need to find cube root of 27, then calculate 0.3 power of 27, result is 3.

And one another method for this program is use **cbrt()** function it is pre-defined in math.h header file.

* cbrt()* is a predefined function in math.h header file, it is used for calculate cube root of any number.

Here is source code of the C++ Program to find Cube Root of a Number using pow( ) function. The C++ program is successfully compiled and run(on Codeblocks) on a Windows system. The program output is also shown in below.

**SOURCE CODE : :**

**SOURCE CODE : :**

/* C++ Program to find Cube Root of a Number using pow( ) function */ #include<iostream> #include<math.h> using namespace std; int main() { int num; double ans; cout<<"Enter number which u want to find cube root :: "; cin>>num; ans=(double)pow((double)num,(double)1/(double)3); cout<<"\nCube Root of [ "<<num<<" ] is :: "<<ans<<"\n"; return 0; }

**Output : :**

**Output : :**

/* C++ Program to find Cube Root of a Number using pow( ) function */ Enter number which u want to find cube root :: 125 Cube Root of [ 125 ] is :: 5 Process returned 0

Above is the source code for C++ Program to find Cube Root of a Number using pow( ) function which is successfully compiled and run on Windows System.The Output of the program is shown above .
