问题 Suppose I have the words: tiger, lion, giraffe. How can I store it in a two dimensional char array using for loop and scanf and then print the words one by one using a for loop? Something like for(i=0;i<W;i++) { scanf("%s",str[i][0]); //to input the string } PS Sorry for asking such a basic question, but I couldn't find a suitable answer on Google. 回答1: First you need to create an array of strings. char arrayOfWords[NUMBER_OF_WORDS][MAX_SIZE_OF_WORD]; Then, you need to enter the string into

问题 I have used adist to calculate the number of characters that differ between two strings: a <- "Happy day" b <- "Tappy Pay" adist(a,b) # result 2 Now I would like to extract those character that differ. In my example, I would like to get the string "Hd" (or "TP" , it doesn't matter). I tried to look in adist , agrep and stringi but found nothing. 回答1: You can use the following sequence of operations: split the string using strsplit() . Use setdiff() to compare the elements Wrap in a reducing

问题 In Perl I can repeat a character multiple times using the syntax: $a = "a" x 10; // results in "aaaaaaaaaa" Is there a simple way to accomplish this in Javascript? I can obviously use a function, but I was wondering if there was any built in approach, or some other clever technique. 回答1: These days, the repeat string method is implemented almost everywhere. (It is not in Internet Explorer.) So unless you need to support older browsers, you can simply write: "a".repeat(10) Before repeat , we

问题 Is there a way to access a character in a string in fortran? If I wanted to store the first letter of a the string "taco" in a character variable how would I do that? 回答1: Character variables and constants can be "substringed" using a syntax similar to an array section. a_character_variable = "taco"(1:1) A substring of a character variable is also a variable - it may appear on the left hand side of an assignment statement. 来源： https://stackoverflow.com/questions/36487824/fortran-procedure

问题 I understand pointers (I think), and I know that arrays in C are passed as pointers. I'm assuming this applies to command-line arguments in main() as well, but for the life of me I can't do simple comparisons on command-line arguments when I run the following code: #include <stdio.h> #include <stdlib.h> #include <string.h> int main(int numArgs, const char *args[]) { for (int i = 0; i < numArgs; i++) { printf("args[%d] = %s\n", i, args[i]); } if (numArgs != 5) { printf("Invalid number of

问题 In a very busy PHP script we have a call at the beginning to "Set names utf8" which is setting the character set in which mysql should interpret and send the data back from the server to the client. http://dev.mysql.com/doc/refman/5.0/en/charset-applications.html I want to get rid of it so I set default-character-set=utf8 In our server ini file. (see link above) The setting seems to be working since the relevant server parameters are : 'character_set_client', 'utf8' 'character_set_connection'

问题 don't think I haven't searched online for an answer. Why is it giving me outofbounds error? I have two 6-chars long strings. One is "daniel" and another is "------". User enters a character. Loop goes through the "daniel" string and checking char by char is they match with the user input. If it matches, it should replace the guessed char with the one in "------". So if you input 'a' it should output "-a----" and the loop continues. Next if you enter 'e' it should output "-a--e-" etc. Code
