[Solved] SIGABRT called when calling find() on a string element in an array [closed]

[ad_1] It’s pretty simple why it’s crashing when you change that line. In the version that crashes you check whether words[j].find(new_word) is equal to std::string::npos and then call s.erase(s.find(new_word), …). Of course, s.find(new_word) could still be std::string::npos, and string::erase throws an exception when the first argument is out of range. In the version that you … Read more

[Solved] Berkeley DB C++ showing incorrect key-value string data

[ad_1] Solution was to change datatype of key values from constant character pointer const char * to char array. char fruit[sizeof(“fruit”)] = “fruit”; char apple[sizeof(“apple”)] = “apple”; Additionally , even using string instead of const char * for key-values gives similar issue as mentioned in the question, somehow I could make it work only with … Read more

[Solved] Why is this programming style not used? [closed]

[ad_1] I think this style is not used, because the best practice is to split up code into small functions/classes/methods anyway. This way, the variable count in each scope is reduced without using scoping blocks. Unlike other languages, like Rust, where scoping has immediate consequences on memory allocation, I don’t see a huge benefit in … Read more

[Solved] how can I square the numbers between 0 and any input with extremely large numbers in python [closed]

[ad_1] If I am interpreting your question correctly, you simply need to devise a very simple list comprehension program. Getting the square root of everything between zero and n is not necessary. Did you mean square? Here’s my solution: def nbDig(n,d): int_list = str([str(x*x) for x in range(0,n+1)]).count(str(d)) return int_list I can test it like … Read more

[Solved] How can I retrieve data from two different const and put it in a for [closed]

[ad_1] You can create a method getObjByKey to find in the provided arr array the object that contains key property and use Destructuring assignment the get the value Code: const getObjByKey = (key, arr) => arr.find((obj) => Object.entries(obj).find(([k, v]) => key === k)); Then you can do: const { data2 } = getObjByKey(‘data2’, date1); const … Read more

[Solved] Error while compiling the code ‘double free or corruption (out)’ using threads in C? [closed]

[ad_1] The *fp is a global variable, so each therad will initialize it with fopen and after finished working try to close it. the *fp is shared between threads (which should not be) so each thread before exiting tries to close the file handle stored in *fp and the double free occurs when multiple threads … Read more
