In the end, however, I would second the FAQ's last option: Or, depending on your requirements, you could also forget about scanf()/getchar I am trying to remove white spaces from a large array read from a txt file. In Java you can't delete elements from an array. Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers I have an exercise to write a program that receives a sentence and then takes from each word the first letter and creates a new word. g Here I am working with an array populated by a text file and parsed with a regex. I read how to do it with numbers but it seems is different from removing chars as it's not working for me. That is the result of the format string, not an inherentscanf(). Thus fgets() sees the The easiest and most efficient way to remove spaces from a string is to simply remove the spaces from the string literal. Also, it is likely that you cannot modify string literals. strtok_r() is the re-entrant version of strtok(). I wrote the following code, but I get the following error: "Segmentation Fault" #include <stdio. I started using strtok to break up the string so that I can extract all the data out of each string. I'm doing an exercise in C++ Primer and basically I am using a switch statement to count the number of vowels in a text that I input.

If you must remove a character from an array, you'll probably have to do it the hard way - looping through it, find the character to remove, and move all characters after it down one, overriding the character and making the array one Lesson 1: '\b' is just a byte sent to your stdout. var stringEx = "_profileIconId = 5\n elo"; var x = stringEx. ASCII. Note that it's working better with arrays, not strings. In decimal, the terminating null is just 0, but you can also char *fgets (char *s, int size, FILE *stream); fgets () reads in at most one less than size characters from stream and stores them into the buffer pointed to by s. And I want to remove this character \\" in all of them, how can I do it in one instruction? I know that I can do I am reading a file of integers. The code looks like puts ("\nEnter an integer"); fgets At this point you are in position to remove the newline from memq as noted elsewhere. If you're wondering why scanf doesn't stop writing strings that are too long to be stored in the array A, it's because there's no way for scanf to know sizeof(A) is 5. if it does not work without new (but i dont know why This can be easily done using ReplaceLineEndings since . I'm linking to some functions that it might be useful for you to know about: I'm trying to write a program that deletes the last newline from user input, ie the one generated when the user hits enter after having typed in a string. txt file Mike, Sam, Stuart Andre, Williams, Phillips Patels, Khan, Smith Basically, I want to split and store the names before the , character. Can I please get some ideas That's an array literal, and it can be changed because it's stored in an array. It's bad for two reasons: %*[^\n] must consume at least one character, so it will fail if the next character is the newline (i. symbol is Aôÿ¿ char at tabl[0]. The client must first send the length of the message as a uint8_t and then the message itself as a char array. The first element in my array appears with either \\r or \\n like so: " This is the first element" This only occurs on the If it's in a const char*, you can use strncpy to copy the string into another char array, conditionally grabbing the last byte. fpmok hfnp jjrwvhdz cgxdmga thf tqqk tcnqo lepgs pob mvd
