In this post, we will write a **C++ program to calculate the square root of a given number**.

## C++ program to calculate the square root of given number.

```
#include<iostream>
#include<conio.h>
#include<math.h>
int main()
{
system("cls");
int n;
float res;
std::cout<<"Enter any number = ";
std::cin>>n;
res = sqrt(n);
std::cout<<"The square root of number is = "<<res<<std::endl;
getch();
return 0;
}
```

### Output

Enter any number = 64 The square root of number is = 8
