norm() function in C++ with Examples

The norm() function is defined in the complex header file. This function is used to return the squared magnitude of the complex number z. Syntax:

template<class T> T norm (const complex<T>& z);

Parameter:

• z: It represents the given complex number.

Return: It returns the squared magnitude of the complex number. 

Time Complexity: O(1)

Auxiliary Space: O(1)

Below programs illustrate the above function:- 

Example 1:- 

The norm of (5,12) is 169

Example 2:-
