Use of fread() in C? How to use fopen() in C? Use of if condition in C programs. Dangling, Void , Null and Wild Pointer. How to use fgets() in C? C program to convert uppercase to lowercase and vice versa in file File handling in C, In a few hours. C program to display ...
When to use while loop in C. In the last, I have used fclose to close the open file. //close the file fclose(fp); Difference between fgetc and getc in C. The getc function is equivalent to fgetc but getc could be implemented as a macro. Because of the getc implemented as a macro...
Usually, one just uses fgets() (or getchar() in a loop). Back to scanf(): If you have compile time limits, you can use #define stringize(s) #s #define XSTR(s) stringize(s) #define BUFSIZE 20 char *buffer = malloc(BUFSIZE+ 1); if (buffer) { if (1 == scanf("%"XSTR(B...
In this modified example, we use awhile(1)loop and explicitly check forEOFafter attempting to read a character. IfEOFis encountered, we usefeofto confirm that it is indeed the end of the file. feofis often used in conjunction with other file stream functions likefread,fgets, andfscanfto ...
Use fgets() instead. ... ### Seems clear enough to me. Unfortunately, idiots continue using a library routine that should never have existed *ever*. It is fundamentally broken, always has been and always will be. And there is a replacement that is simple enough to switch ...
s pathname, which can’t be retrieved if not passe explicitly as a command-line argument. Mind though, every function call needs to be checked for a successful return to guarantee thefgetsdoes not try to write to the uninitialized memory region and cause the program to terminate with failure...
if (fgets(line, 16, fr) == NULL) { flock(fr, LOCK_UN); fclose(fr); exit(0); } int ctr = atoi(line); ctr++; fprintf(fr, "%d", ctr); flock(fr, LOCK_UN); fclose(fr); } I know that I should not use "fr" as the parameter of flock, but I dont know how to get a...
You might want to consider using fgets instead:https://en.cppreference.com/w/c/io/fgets Last edited onApr 29, 2019 at 9:52pm Apr 29, 2019 at 9:57pm George PlusPlus(5756) As Peter87 said,gets()has been removed from the latest standards. If you don't want to usefgets()there is...
called str with a size of 100. The user’s string is then read using thefgets()method. Thestrupr()method is then used to transform the string to uppercase. Thestrupr()method receives the str array as an input. Lastly, we use the printf() function to output the final uppercase text....
Otherwise you can use fgets and convert using atoi() or some such.I hope this is of some help.Steve4980000 (Computer) (OP) 7 Jun 01 11:22 hi! SteveThanks again for your Suggestions!Steve as u have said to use file handling to create a database i will do so.I have copied your...
