I want to execute my programs in code blocks but I don't know what the problem is. When I try to run my program it says that "It seems that this file has not been built yet" , and when I press the build button it doesn't do anything !!!

I am very new to coding, it being only 3 weeks until I have started to learn to code. I write very small codes as of now (like only 20-30 lines, maximum 44) Whenever I write a code, then run it, as you might know, that if I have written a code for finding if the number is prime or not, I have to write in the terminal, ./prime and then press enter, then input a number.
But, when I do that in my VS code software, when I write, ./prime and then press enter, it shows:
bash: ./prime: No such file or directory.
I observed that my teacher is using that terminal in git bash, so I installed GitHub and used git bash for it, still, this problem was occurring. My brother predicted that you might not be saving the file, do that and then play it on the terminal. I even did that, but still, it was happening. And this is happening with every code I am typing, all the 44 code files.
Idk if this is happening because I have missed to download a particular file of mingw, or is there a different method to do that, for windows(my OS), because my teacher uses mac
You need to compile your code before you execute.
In terminal run command gcc prime.c -o prime and then you are good to go with ./prime
There's this bug with the placement of certain characters in the embedded terminal in CLion (the Run tab that pops up when you click the Run button), and I figured out that if I changed the terminal in CLion, that wouldn't happen. I changed the terminal to cmder, and it is all working now, except one thing: I can't figure out how to make CLion run the program to that terminal.
I tried changing the configuration, but all it did on run was open cmder but not execute the program (I had to run it manually, by writing the file name).
I wonder, what's the way to fix this, and make CLion directly run C programs on the terminal, instead of the Run tab?
Thank you.
The CLion run configuration always runs in the integreted run window. That is not a terminal emulator, and it cannot be changed so that it runs in an actual terminal emulator (like cmder).
Your best bet is to try to fix the "character placement" in the run window. Maybe ask a different question where you explain the issue, or if it's a clear bug, file a bug report for it.
Thanks.
So when I write some code into codeblocks using c language and run it, granted the code is error free, it runs fine. Subsequent modifying and running of the code only produces the results of the first time I ran the code unless I delete the executable and object files. In other words it is not updating to the code that I modify. I am running the latest version of CodeBlocks. Is this a setting I need to change?
Update:
After reading the answers and comments below, I was able to correct the problem. As many suggested I indeed needed to click "build and run". I know it's such a basic question but I'm new to programming so thanks for your help. The confusion came when I would first click to "run" a code it would automatically ask me if I wanted to build it first. So I just thought every time I clicked "run" it would automatically build it first.
In Codeblocks, there should be a "Build and Run" button to fix your problem assuming that you were only pressing "run" before you read this
Build and Run Screenshot
I had to write code in C and run it for an assignment. Since this is the first time that I'm using C, I downloaded MinGW as a compiler and Code Blocks as an IDE. I had no problem compiling the code given by my professor but it never runs (this is a simulation for an M/M/1 queue). When I say it never runs, I mean that a command prompt like window pops up and nothing happens after that. Every time I close that window and try to compile the SAME program again, I get an error that says that permission to access the file has been denied.
I then deleted Code Blocks and tried running the program through command prompt but I have the same problem. I've now tried doing it using LCC-Win but nothing has changed. Another weird thing that happens when I run any program is that three instances of the .exe file of that particular program are in my processes under task manager. I then need to restart my computer to try compiling that same program.
I even tried running a simple Hello World program and I have the same problem!
I am currently using a Windows 7 32-bit system.
Any help would be greatly appreciated!
I searched for a solution to my problem already in Google and here in stack overflow.
I didn't found an understandable and precise solution for my problem:
I've written a program that maintains an inventory.
It compiled without warnings or errors and it works quite well when I type in commands by hand. When I'm running the program with an input file with much more parts I get a segmentation fault 11.
Now I want to debug my program but don't know how to do this using input files.
I already did some debugging via the CodeBlocks IDE. Didn't find a option for this.
I used malloc and realloc functions in my program and think the error happened there because I never used it before.
Could you please help me in following ways:
I need a debugger that can debug while the program runs with an input file.
The debugger must be able to check for memory leaks or things like this.
Thanks

Debugging with command line input vs. Debugging with a input file is the totally same.
You must understand this.
When you start debugging session in the IDE, it is by default 'no input' mode (no input file).
But you can specify startup conditions for the program, including working directory, command line arguments, etc.
By using these options, you can run the debugging session exactly same as user running the program with input files.
