How to using switch statement with string variables or values?

Question

Hi, I am a newbie in C++ programming. I am making a CLI Calculator which will perform operations by input from the user. so I need multiple conditional statement like SWITCH but that does not work. It says it wants to be an integer one. is there anyway in which I can get string input from user and evaluate multiple conditions based on that input.
Thanks in Advance

Answer 1

A switch can only use integral types, like char, int, long long.
But a string is not an integral, so it can't be used there.

The if ... else is the way to go in those cases.

You could make a switch work with strings by implementing a compile time hashing function, which basically converts a string into an integer.
But that's probably not something to dive into as a beginner.
Just making you aware of it.

Answer 2

if switches ask for numerical types, then dont make life difficult. If, else ifs, and else will replace cases and default easily 😃
