C++ program to find square root and cube root of number
Description :-
A wide number of useful mathematical functions are available in C++.
These functions are included in standard C++ and can be used to
perform a variety of mathematical calculations. These functions,
rather than focusing on implementation, can be used to immediately
reduce code and applications. C++ has a significant number of
mathematical functions. To utilize these functions, you must include
the header files <math.h> and <cmath>.
C++ sqrt( )
using namespace std;
void square_root(float number) {
double result = sqrt(number);
cout << "\nThe square root of the number is : "<< result ;
}
void cube_root(float number) {
double result = cbrt(number);
cout << "\nThe cube root of the number is : "<< result ;
}
int main() {
float num;
cout << "Enter number number : " ;
cin >> num;
square_root(num);
cube_root(num);
}
The sqrt() function in C++ returns the square root of a number.
This function is defined in the cmath header file. If the number is
not a perfect square, then return floor(√x).
C++ cbrt( )
The cbrt() function in C++ returns the cube root of a number. This
function is defined in the cmath header file. If the number is
not a perfect cube, then return floor(3√x).
parameter :- The sqrt( ) and cbrt( ) function takes a single argument
whose square root & cube root is to be calculated.
Code
using namespace std;
void square_root(float number) {
double result = sqrt(number);
cout << "\nThe square root of the number is : "<< result ;
}
void cube_root(float number) {
double result = cbrt(number);
cout << "\nThe cube root of the number is : "<< result ;
}
int main() {
float num;
cout << "Enter number number : " ;
cin >> num;
square_root(num);
cube_root(num);
}
Output :-
Enter number number : 64
The square root of the number is : 8
The cube root of the number is : 4
The square root of the number is : 8
The cube root of the number is : 4
