[ad_1] 1) scanf(“%s”,input) and not scanf(“%s”,&input) input holds the address of the array. &input passes the address of input. 2) Syntax of for loop is: for ( init; condition; increment ) { //code } Hence the for loop should be: for(i=0,j=c-1;i<=j && j>=0;i++,j–) 6 [ad_2] solved can’t understand where is syntax error [closed]
[ad_1] Example JSON String string data = “{ \”A\” : \”1\”, \”B\” : \”2\”, \”C\” : \”3\” }”; Deserializing it into an object that will contain each of the keys and their values object yourObject = new JavaScriptSerializer().DeserializeObject(data); 1 [ad_2] solved Convert JSON string to data array using javascript or c# [closed]
[ad_1] You need to add string terminators ‘\0’ to your string before printing (or zero out the buffers memory first). Also: you have declared buffers of size 20, but have no guards in your code to respect that allocated length, which means you could overrun them and corrupt memory. [Run with two words greater than … Read more
[ad_1] You can’t if you define them as int. Try with double or float instead. double x; double y; double div; Changing the definition solves the problem. 0 [ad_2] solved How do I get decimals in C++ if I’m using integer variables
[ad_1] The operator precedence of C++ is the standard mathematical precedence, where % has the same precedence as /. So, the expression m = 605 / 10 + 45 % 7 + 29 % 11; would be evaluated as m = (605 / 10) + (45 % 7) + (29 % 11); Which would result … Read more
[ad_1] #define is a preprocessor directive, not a statement or declaration as defined by the C grammar (both of those are required to end with a semicolon). The rules for the syntax of each one are different. [ad_2] solved Why does #define not require a semicolon?
[ad_1] As suggested you can use sort #include <iostream> #include <vector> #include <algorithm> using namespace std; int main () { std::vector<string> vec={“abc”,”defsf”,”a”,”c”}; cout<<“Unsorted string”<<endl; for(auto s: vec) { cout<<s<<” “; } std::sort(vec.begin(),vec.end(),[](const string& a,const string& b) { return a.size()<b.size(); }); cout<<endl<<“Sorted string”<<endl; for(auto s: vec) { cout<<s<<” “; } return 0; } [ad_2] solved how … Read more
[ad_1] I think you’d like to separate all of the words in this sentence, so you can’t make loop stop when it meet first blank. #include<iostream> using namespace std; int main() { char sentence[100]={‘\0’}, word[100]={‘ ‘}; cin.getline(sentence,100); for(int i = 0; sentence[i] != ‘\0’; i++) { word[i]=sentence[i]; } cout << word; } Above code may … Read more
[ad_1] Homework or not, here’s one way to do it. It’s heavily influensed by stemas answer. It uses Regex to split the alphabetical from the numeric. And PadLeft to maintain the right number of leading zeroes. Tim Schmelters answer is much more elegant, but this will work for other types of product-numbers as well, and … Read more
[ad_1] Setting isBodyHtml to true allows you to use HTML tags in the message body: SmtpClient sc = new SmtpClient(“mail address”); MailMessage msg = null; try { msg = new MailMessage(“[email protected]”, “[email protected]”, “Message from PSSP System”, “This email sent by the PSSP system<br />” + “<b>this is bold text!</b>”); msg.IsBodyHtml = true; sc.Send(msg); } catch … Read more
[ad_1] Neither iteration of the loop will be executed. In fact this loop (provided that the condition has no side effects) for(i = 2; i < 2; i++) { /* … */ } is equivalent to this statement i = 2; [ad_2] solved In C, what happens when the condition for a for loop aren’t … Read more

[ad_1] I assume you’re talking about Basic Http Authentication, if you’re using HttpClient to make your web service calls then you can enable set a Basic authentication header with the following code. var request = new HttpRequestMessage(HttpMethod.Get, uri); var token = Convert.ToBase64String(Encoding.UTF8.GetBytes(String.Format(“{0}:{1}”, username, password))); request.Headers.Authorization = new AuthenticationHeaderValue(“Basic”, token); The simplest (and cleanest) way, however: … Read more
[ad_1] A minimal hello world program in C looks like this : #include <stdio.h> int main() { printf(“Hello World\n”); return 0; } You first have to include stdio.h which gives you access to the printf function. Then you have to define a main function which is the entry point of the program. The code inside … Read more
