this is my code : #include <stdio.h> #include <stdlib.h> #include <string.h> int main(int argc, char **argv) { char db_names[3][36] = {}; strncpy(db_names[0], "6e64e40c-57f6-11ec-91ca-001a6496977d", 36); strncpy(db_names[1], "90e852c8-502d-11ec-91ca-001a6496977d", 36); strncpy(db_names[2], "28712b0e-57f6-11ec-91ca-001a6496977d", 36); printf("index 0 %s\n", db_names[0]); printf("index 0 %s\n", db_names[1]); printf("index 0 %s\n", db_names[2]); return EXIT_SUCCESS; } print element in array : index 0 : 6e64e40c-57f6-11ec-91ca-001a6496977d90e852c8-502d-11ec-91ca-001a6496977d28712b0e-57f6-11ec-91ca-001a6496977d index… Read More Please help, why we get wrong element in array,

I have a for loop in randomString() that puts a random character into the first x indexes of a string, where x < the string length. I then add a ‘\0’ to the string and print it with printf() but it prints 1 more character than x and that character is always the same, I… Read More printf() is printing a character after the terminating character in C, how do I fix this?

I have been attempting to parse a string into separate tokens for a command line interface for a project of mine, I have created this function to do it: char **string_parser(char *input) { char **output = (char **) malloc(sizeof(input)); int word_num = 0; int word_index = 0; for(int i = 0; i < strlen(input); i++)… Read More segmentation fault when accessing pointer element

I have a string and I want to split it into words. The code works when the string passed ends with a space, but not otherwise CODE: void form_rule2(char * str) { int num_words=0; char word[20]; while(sscanf(str,"%s",word)==1) { num_words++; printf("%s\n",word); str+=strlen(word)+1; } } void main() { form_rule2("abcd efgh! ijkl mnop"); } The output I get… Read More Why does the following code not work as intended

My codes is suppose to replicate the strncat() function. The codes give the desired output, but it always ends up with the stack smashing detected error. I’d like to know why and how to fix it. What am I doing wrongly or not doing at all? main.h #ifndef MAIN_H #define MAIN_H #include <stdio.h> #include <string.h>… Read More Stack smashing detected (Aborted Core Dump)

I am separating a string into words and when I run the source code, it works but at the end it displays random symbols and letter. #include <iostream> #include <cstring> #include <cctype> using namespace std; void seperatestring(string str); int main() { string str; cout << "Enter a string: "; getline(cin, str); seperatestring(str); return 0; }… Read More When I run my code it display random symbols at the end

I know there are other ways to solve this like with a calloc but the question here is why does it work while it shouldn’t? #include <stdio.h> #include <stdlib.h> #include <string.h> void function (char **, char **); int main () { char *list[2], *list1[] = {"word0", "word1", "word2"}; function(list, list1); return 0; } void function… Read More This simple C code about string arrays works while it shoudn't and I don't know why

I wanted to read a phrase and a series of numbers/alphabetic separated by ",". I read the first string then I print it (works fine). I read the first string, read 62 of those series and try to print the first string again and is not working. I tried a lot of methods but none… Read More Why I cannot access the first read char array after reading a series of others in C?

Hi I was wondering if there is an alternative of str.substring() in string.h. If not, what is an efficient alternative? >Solution : Assuming that we all agree that using c++ it is safer and more professional to use the standard library tools. That said, if we’re talking about C and not C++, this should be… Read More Alternatives for str.substr using <cstring> library?

I have to get a string from keyboard, and then print only the numbers from the char, but with the actual value. **Example ** Input: I am 19 years old output: 19 (as an integer) I wrote this code, but I cant convert it whatever I do. #define _CRT_SECURE_NO_WARNINGS #include <stdio.h> void main() { char… Read More How do I convert Char to Int, with the value remaining the same?
