I am very new to the concept of programming in C. I am wanting to have a multi condition if statement using the (or) and the && (and) in one statement. When I ask my college professor about it. She told it was possible and then insulted my limited knowledge on the subject. C Advanced. If else statements in C is also used to control the program flow based on some condition, only the difference is: it's used to execute some statement code block if the expression is evaluated to true, otherwise executes else statement code block. In a short and basic testing C program I made the if, else if and else statement do not appear to be working. Regardless of what answer you input the if, else if and else statement just auto jumps straight to the else statement and I don't understand why.

Sometimes when creating a C++ program, you run into a situation in which you want to compare one thing to a number of other things. Let's say, for example, that you took a character from the user and wanted to compare this to a number of characters to perform different actions. For now, let's just say that you have three commands which operate from the keys: 'h', 'e', and 'q'.
We can use an if-statement to check equality to
'h'
, 'e'
, and 'q'
- remember that we use single quotes because we're dealing with chars, not strings. P2p wifi camera software for mac. So let's just write the code in the way we're used to (and let's wrap a while loop around it so it keeps getting a character and acting upon what it was, because that makes our program slightly better and easier to test), using if-statements, like the following:This program should be something you're comfortable with creating by this point, however your programmer instincts should also be kicking in and telling you that you shouldn't be repeating so much code here. One of the core principles of object orientated programming is DRY: Don't Repeat Yourself. In this program we're having to repeat a lot of code for the 'else if's including using

every time we're doing a comparison.Wifi map app for mac. The solution to this 'problem' is what this tutorial is all about: switch statements. These are essentially just a really nice way to compare one expression to a bunch of different things. https://lightningheavy260.weebly.com/cooking-tycoon-unlimited-coins-and-gems-download.html. They are started via the
switch
keyword, and from there comparisons are made using a case:
syntax. It isn't easily described in words, so take a look at the syntax below:https://tracabdel.hatenablog.com/entry/2020/11/23/111123. How to do double auto tune. The different
case
s essentially act as many if/else-ifs in a chain, and an 'else' type clause can be specified by using default

This type of functionality should be reasonably easy to understand with if-statements securely under your belt, and so if you're feeling brave - try porting the basic program we created at the start of this tutorial to use if-statements. If you're not quite that brave, the cleaner and neater
