How to use mul function

The mul function is a function used to perform multiplication operations and is used to calculate the product of two or more numbers.

#In different programming languages, the mul function may have different usages. Generally speaking, the mul function is a function used to perform multiplication operations, used to calculate the product of two or more numbers. Here are some common usage examples of the mul function:

mul function in JavaScript:

function mul(a, b) {
  return a * b;
}
console.log(mul(2, 3)); // 输出：6
console.log(mul(4, -5)); // 输出：-20

In JavaScript, the mul function accepts two parameters a and b and returns their product.

mul function in Python:

def mul(a, b):
  return a * b
print(mul(2, 3)) # 输出：6
print(mul(4, -5)) # 输出：-20

In Python, the mul function is similar to its usage in JavaScript. It accepts two parameters a and b and returns their product.

The mul function in C (using namespace std):

#include <iostream>
int mul(int a, int b) {
  return a * b;
}
int main() {
  std::cout << mul(2, 3) << std::endl; // 输出：6
  std::cout << mul(4, -5) << std::endl; // 输出：-20
  return 0;
}

In C, the mul function accepts two integer parameters a and b and returns their product. Call the mul function in the main function and print the result.

These are just some examples of common uses of the mul function, and the specific usage depends on the programming language and context used. In actual development, pass appropriate parameters to the mul function as needed, and use its return value for subsequent operations.
