Square Root Program in C++

Square Root of Number program in C++

# Important Points:

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

Example:

Given number: 1296

Square root: 36

# Algorithm

1. Declare a variable called number to store the number whose cube root you want to calculate.
2. Declare a variable called root to store the result of the cube root calculation.
3. Prompt the user to enter the number whose cube root they want to calculate, and store the input in the number variable.
4. Use the sqrt() function from the math library to calculate the cube root of the number and store the result in the root variable.
5. Print the result stored in the root variable to the console.

Code:

#include<iostream>
#include<math.h>
using namespace std;

int main(){
  float number, root;
  cout << "Enter number whose root is to be found: ";
  cin >> number;
  root = sqrt(number);
  cout << "Square root of " << number << " is " << root;
  return 0;
}

Output

Enter number whose root is to be found: 16
Square root of 16 is 4
