  • I NEED HELP WITH AN ASSEMBLY PROJECT!!!
    My Professor has not provided any resources or material to help complete this project, I have tried to problem solve, use the internet, even chatgpt. (I can send the code that it gave me in comments if needed, but ) I need help completely this assignment hopefully by midnight PST tonight. I am using an online compiler (rextester.com). Any help would be greatly appreciated, here is the project description below. Source: over 3 years ago
  • Why is Zig so much more successful than Crystal and Nim?
    Does it really do that? (I've just tried in rextester.com, it complains about declared but unused variables.). Source: over 3 years ago
  • Trying to do errors right
    (A quick survey of some of the languages at rextester.com showed that they are usually counted from 1. I'd suggest doing the same would be least surprising.). Source: about 4 years ago
  • void main() vs int main()
    Some clangs (eg. The one on rextester.com) accept the spam() program too. Source: over 4 years ago
  • I have added named function parameters to my programming language. What do you think, why do most mainstream programming languages not have it, when it is easy to implement in a compiler and it makes it easier to initialize complicated objects with many default rarely-changed parameters?
    On Windows, C compilers tend to evaluate right-to-left. On rextester.com, gcc and clang evaluate as you suggest. Source: almost 5 years ago
