[ad_1] Since you are sure the string will contain digits, subtract each character from ‘0’ to get their numeric value. int sum = 0; fgets(str, sizeof str, stdin); char *s = &str; while(*s != ‘\0’) { sum += *(s++) – ‘0’; } printf(“the sum of the digits is: %d”, sum); [ad_2] solved Splitting a string … Read more
[ad_1] It’s really easy to make a regular expression to get matches: string[] input = new string[6] { “[email protected]”, // match “[email protected]”, // match “[email protected]”, // match “[email protected]”, // not a match “[email protected]”, // not a match “[email protected]” // not a match }; string pattern = @”Auto_gen_\d{4}@mail.com”; //\d{4} means 4 digits foreach (string s in … Read more

[ad_1] You can use this code. here I’m using string for demo, you can use your guid. var list = new List<string> { “a”, “b”, “c”, “d”, “e” }; var threashold = 2; var total = list.Count(); var taken = 0; var sublists = new List<List<string>>(); //your final result while (taken < total) { var … Read more
[ad_1] Hmmm, I haven’t tested it. I hope it helps you. I would do it using two foreach inside the main while SearchResultSet results = session.Search(searchRequest); results.GetCount()); IEnumerable columns = results.GetColumns(); bool printColumns = true; while (results.HasNext()) { if(printColumns){ foreach (string column in columns) { Console.WriteLine(String.Format(“{0}|”, column)); //Will print Unique_ID|Address|etc… } } printColumns = false; … Read more

[ad_1] Excel freezes on Open/Save As if a managed add-in is registered with a “Warmup” registry value, even if the add-in is not even loaded. The “Warmup” registry value, when set to 1 in an add-in’s registry key, was once supposed to cause Excel to load the VSTO runtime at startup, rather than when the … Read more
[ad_1] Lets work backwards here – your stored proc will never work, you have not specified a field for the where, and it has 2 missing close parentheses. select * from MyTable where between CAST(@startDate AS VARCHAR(100) and CAST(@EndDateAS VARCHAR(100) should be select * from MyTable where SOMEFIELD between CAST(@startDate AS VARCHAR(100)) and CAST(@EndDateAS VARCHAR(100)) … Read more
[ad_1] The second example doesn’t have any delay in the execution. The first example only increments the opacity value once then waits for the next timer job. The second example keeps incrementing until its value is one in the first timer job hence no delay. You could add a wait into your do while or … Read more
[ad_1] Yes, the Qt Creator for Windows installer includes Mingw. (Clang isn’t really in a usable state at the moment for Windows.) Note however that the included Mingw version may be badly out of date. 1 [ad_2] solved Is “Qt Creator 2.4.1 for Windows (53 MB)” includes mingw or clang? [closed]
[ad_1] You haven’t provided example values of p.y and sign_y, so it’s difficult to tell for sure. But the problem is almost certainly that p.y * sign_y is not exactly equal to 180; however it will be rounded when you print it. I suspect that if your print the value of (p.y * sign_y) – … Read more
[ad_1] Let p1, p2, p3, … pk be the prime factors of some positive integer n. By the fundamental theorem of arithmetic, n can be represented as p1e1•p2e2•p3e3• … pkek for some positive integers e1, e2, e3, … ek. Furthermore, any such set of such positive integers represents one positive integer in this way. Every … Read more
