C++ <cmath> - hypot() Function

The C++ <cmath> hypot() function returns square root of sum of squares of two arguments, i.e., sqrt(x² +y²).

Syntax

C++11

double hypot (double x, double y);
float hypot (float x, float y);
long double hypot (long double x, long double y);
double hypot (Type1 x, Type2 y);

Parameters

`x`	Specify a value.
`y`	Specify a value.

Return Value

Returns sqrt(x² +y²).

Example:

In the example below, hypot() function is used to return sqrt(x² +y²).

#include <iostream>
#include <cmath>
using namespace std;
 
int main (){
  cout<<hypot(3, 4)<<"\n";
  cout<<hypot(5, 12)<<"\n";
  cout<<hypot(8, 15)<<"\n";  
  return 0;
}

The output of the above code will be:

5
13
17
