Square root in C++ can be calculated using **sqrt()** function defined in **math.h** header file. This function takes a number as an argument and returns the square root of that number.

Below I have shared a program to find square root in C++. If you have any problem then you can freely ask it by commenting below.

## Program for Square Root in C++

1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
#include<iostream> #include<math.h> using namespace std; int main() { float sq,n; cout<<"Enter any number:"; cin>>n; sq=sqrt(n); cout<<"Square root of "<<n<<" is "<<sq; return 0; } |

**Output**

Enter any number:9

Square root of 9 is 3
