Hey, I am building a library that allows you to print a progress bar. Currently, I enable the user to select a common character. However, the issue arises when I attempt to allow the user to pass Unicode characters, as the '\u' throws an error. Specifically, '\u' is being used without any following hex digits. Here's the relevant code snippet: printf("\x1b[38;5;%dm\u%x", pBar->color, pBar->unicode); I appreciate any ideas or suggestions on how to resolve this. Thanks!" submitted by /u/vaquitson [visit reddit] [comments ..read more

I'm looking for an IDE. What I really need from an IDE: Capable of reading in included libraries (maybe with cmake). Capable of reading headers of function (even from included libraries) and suggesting and visualising it when I write the function. Capable of autocomplete suggestion based ONLY on variable I defined in the scope. No strange vsc stuff I need each time to dismiss with esc or die trying to use arrows to move one. Capable of autocomplete function name based on all the possible functions defined in the libraries I included. Capable of syncing on github. Capable of having various col ..read more

I'm doing some review problems for my next test and I'm trying to store some ints from a file to an int array but a random 7 digit value is getting stored in all the array slots when I print it out. I've tried looking for a fix but can't find any results online. #include <stdlib.h> int main(){ FILE *fptr; int arr[7]; fptr = fopen("numbers.txt", "r"); /*numbers.txt contains: 12 14 15 15 17 28 39*/ if(fptr == NULL){ printf("File unable to open\n"); } else{ printf("File opened\n"); } int i = 0; int j = 0; while(!feof(fptr)){ fscanf(fptr, "%d ", &i); arr[j] = i; j++; } for(int k = 0; k ..read more

Short version: I am looking for a site or book where I can find novice to expert level practice programs specifically for C (not c++, not c#, just c) that also has solutions (possibly multiple) to those problems. Long Version: I'm in my 30s so I already feel out of place in college but I have a great desire to have the ability to be sole provider for my wife and future children. Right now I am going to school for Computer Engineering using the G.I. Bill which pays a monthly allowance supplementing my wifes income. If she were the sole provider we could survive on a tight budget so the G.I. Bi ..read more

How come this works: Char name[20] = "Mary"; But this doesn't. Char name[20]; Name[20] = "Mary"; Am I correct in that the above fails because I'm telling it to put "Mary" in the name[20] element? Is that how it's interpreted? Is there a way to initialize char name[20] array separately from the declaration without using srtcpy()? Just wondering Thanks submitted by /u/apooroldinvestor [visit reddit] [comments ..read more
