Q&A Discussions

can someone please explain to me how moving objects are produced ? (example in games). must I use graphics.h?. how do I transform it from simply a compiled piece of code in code block to a real software?. I've been googling this for days now and I'm still confused. Please an extensive explanation would be appreciated🙏. Thanks. p. s you can also recommend websites where I can learn more and see good sample codes.

* represents multiplication but why is it written like f*, this makes it look like f has an exponent (in module 6 question no 6) it would have made sense if f*I not f*=I that just complicated things for me.

If you were to use a horizontal line and want to make it a certain color, how would you also make its width different? I can't wrap my head around THIS one. for example: --<HR COLOR="#00FF00"/> This makes it green, but I can't add width in there. is there some certain way?

Hi, developers of sololearn! It is really good application for learning languages. But playing games is terrible. Why so little time for each round? If you will add new feature for players to be a to choose the duration of rounds, it would be great.

Apart from the Learn Java app, what books and internet resources would any helpful person on this forum suggest to a college freshman(me) taking intro to CS, and struggling? Right now, I'm struggling with writing my own for loops and nested for loops. I'm really confused. Usually, I'm very good coming up with solutions to analytical problems, but intro to CS is making me feel really dumb. I sincerely need help.

so although using srand(time(0)) can be used to get truly random numbers, how truly random are they? For example, if one were to call this method at the same time (in this example, if one were to use this command at 51s) each time would the numbers generated be the same??? If so, are the numbers still truly random?? And if this theory is true, how can one generate truly random numbers that cannot repeat based on external variables (e.g., time)?

CSS The text-indent property I do not understand why you would use this when the </br> tag takes the text back to the left hand side of the page, and as soon as I start a new class the first line of text in a paragraph even with a class it imprints onto every other paragraph like it or not.

Write a C++ program that retrieves all the numbers stored in a data file named LAB1.TXT. As each number is retrieved, it is displayed on the screen. After the end of file is reached, the numbers should be sorted into numerical order and then the result should be displayed EXAMPLE: Assuming LAB1.TXT has the following numbers: 7 4 12 3 The output would be Original order:7 4 12 3Numerical order:3 4 7 12

so far in section 1 question 2 area all of the videos have been ads that if you skip the add it just brings up the questions you need to answer. also if you play the add all the way thru you get the same exact thing. luckily I'm using this as a refresher course but I would think if I didn't know anything about c++ then I could be pretty lost missing videos.
