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...
How to use fputc. How to create a file in C. Difference between puts() and fputs() There is the following difference between the fputs and puts function. 1.fputs function takes two arguments first is the address of a string, and second is a file pointer. In another hand, puts takes ...
Use the feof() Function in Can article by DelftStack Use thefeof()Function to Check End-Of-File Indicator on File Stream in C As mentioned above, thefeof()function is part of the C standard input/output library, defined in the<stdio.h>header. ...
Notice that, we retrieve a file size usingstatsystem call, but it needs the input file’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...
In the above code, we first declare a character array 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...
To determine the size of your array in bytes, you can use thesizeofoperator: int a[17]; size_t n = sizeof(a); On my computer, ints are 4 bytes long, so n is 68. To determine the number of elements in the array, we can divide the total size of the array by the size of ...
You can use the space-separated string in a program using the fgets() function. The use of the fgets() function is to return a string. What makes it different from the gets() function is that the fgets() function ensures that no more characters than the maximum size are read. After ...
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...
fgets ( bStr, 80, stdin ); printf("\nLong String value:%s \n\n",bStr); return 0; } However, above two methods only can handle normal user input,how about i want to handle user input with 1000 or even more characters? Yes, we can declare like “char bStr[1000]” or even more...
would have taken to fix it (fgets). (2) Use older versions of gcc that don't complain about code constructs that are likely to be buggy. (3) Ignore the warnings. Rainer Weikusat 17 years ago Permalink Post by Joe Pfeiffer Post by Rainer Weikusat ...
