Mobile C { C/C++ Compiler }

I love this app. I have had it for some time and use it a lot. I have done some C programming with it, and am currently using it to improve my knowledge of Python. I don't know enough as a programmer to evaluate everything the app should be expected to do. For example, I don't know C++ and haven't used the app for that. But so far, the app does everything I need it to, and does it well.

The Display GUI doesn’t work properly on the iPad Pro 2020 with Magic Keyboard. I have the latest iPadOS installed, 14.6. Please fix this problem. The app is useless with this problem.

My complaint below, I take it all back. Everything works well when I get the typo’s out of my code, both in the free version, and in the purchase version. The module operator works correctly in both versions of the compiler.😊 I got the full $13.99 version when I had iOS 13, and it works well. I have now a second iPad, and my same code, which I wrote explicitly to not be platform/compiler dependent, nevertheless fails to run with the exact same results as my old version, yet with all the same inputs. My code depends on the module operator a lot, and I did read one review somewhere that the module operator does not work. Well, the module operator must work on the compiler version I spent $13.99 on, because my code works well with that version. Is the $13.99 version even available now? Is it the version with the curly brackets rather than the version with the square brackets? I have tried both, and both fail in the same way as to outputs. Frustrated!

This is an excellent product in every way. The fact that it runs offline is something very special.and the fact that it handles several programming languages makes it one of y favorite apps! I salute the individual or individuals who created it! Thanks from the bottom of my heart!

First complaint... C99 ... why? It was deprecated in 2011. Can’t select a different standard? Second, is there no way to create a project? What use is this app beyond simple hello world crap? The completion is nice. Syntax highlighting is a plus but everything pretty much as that. I don’t understand this useless IDEs existence, or any of the others in the “app store” for that matter. My friend bought this and gifted to me. I am glad none of my money was wasted on it.

This is an adorable tool and I completed first round of learning C++ on it. Though there are weak spots such as exception handling and pointer implementation, it's truly great work for the author to create this tool.

iPhone 6s, Model NKRL2LL/A, SW ver. 13.1.3 It gets 4 stars when these bugs are fixed. If they implement separate compilation then it gets 5 stars. I tried the free version and it had these two bugs. I thought that (maybe) the developer intentionally limited the capability, so I purchased the ~$14 version. Same bugs! Here’s the code, the input and the result. The workaround was for me to use fgets but put a bogus record at the top, fgets and ignore it. However, fscanf is just plain broken. The same code works just fine on other C compilers, e.g., gcc under Linux, mingw32-gcc under Code::Blocks. // fin1.c: Dr. J. Morris // read values from data file via fscanf #include <stdio.h> #include <stdlib.h> #define N 10 int main(void) { double y[N]; // data loaded in this array FILE *ifp; // input file pointer int n; // number of items fscan'ed int i; // array index // open & error check files if((ifp = fopen("rawdata.dat","r")) == NULL) { perror("Error opening input file: "); exit(EXIT_FAILURE); } // read data into array, echo to console printf("fin1: fscanf is broken\n"); printf("raw data (%d values):\n",N); for(i=0; i<N; i++) { n = fscanf(ifp,"%lf",&y[i]); // BROKEN! printf("n = %d, y[%d] = %6.2lf\n", n, i, y[i]); } fclose(ifp); // close file exit(EXIT_SUCCESS); // exit program } rawdata.dat 50.1 100.2 0.2 105.5 20.3 20.0 10.0 200.0 205.0 30.0 Console output fin1: fscanf is broken raw data (10 values): n = 0, y[0] = 0.00 n = 0, y[1] = 0.00 n = 0, y[2] = 0.00 n = 0, y[3] = 0.00 n = 0, y[4] = 0.00 n = 0, y[5] = 0.00 n = 0, y[6] = 0.00 n = 0, y[7] = 0.00 n = 0, y[8] = 0.00 n = 0, y[9] = 0.00 // fin2.c: Dr. J.
