In C + +, we can also integrate functions with the same function to a function, without having to write several functions of different function names, which is called the overload of the function. The following is a detailed analysis of the function
In C ++, we can also integrate functions with the same function into a function without having to write many functions with different function names. This is called function overloading. The following is a detailed analysis of function overloading
