[ad_1] A simple way using std::setw and std::setfill is this: int hour = 0; int minute = 0; int second = 59; std::cout << std::setw(2) << std::setfill(‘0’) << hour << “:”; std::cout << std::setw(2) << std::setfill(‘0’) << minute << “:”; std::cout << std::setw(2) << std::setfill(‘0’) << second << endl; It will print: 00:00:59 0 [ad_2] … Read more
[ad_1] Let’s look at the first two lines of your code: str = (char *) malloc(15); strcpy(str, “63tczfqV4nqB2YnH9iFJbGvGyyDkvK341rrj0G0mo1PEYniOVHejVIFIQnJzHSSMRbuyGMCZ4M5HFMV4y1q4QgYqyxp2XkTjxaolKTkaw1r25S2Emz061tw1”); At this point, you have broken the rules of the C language. strcpy will write past the end of str which causes undefined behavior. Everything that happens after this point is kinda up in the air. 5 … Read more
[ad_1] You can iterate through the String and look for a character you seek. Just use a for loop like this: String test = “I want to test something”; for(int i=0;i<test.length;i++) { char t = test.charAt(i); // do something with char } https://docs.oracle.com/javase/7/docs/api/java/lang/String.html#charAt%28int%29 3 [ad_2] solved How to get a character index in a string … Read more
[ad_1] From the str.find() method documentation: Return -1 if sub is not found. So the first if condition tests if string1 is found in x; if it is, a value other than -1 would be returned. The second if condition tests if two strings are not present in x (because only then -1 is returned … Read more
[ad_1] In Python 3.2 and higher, representing a container with all integers from 1 to a million is correctly done with range: >>> positive_nums_to_1M = range(1, 1000001) >>> 1 in positive_nums_to_1M True >>> 1000000 in positive_nums_to_1M True >>> 0 in positive_nums_to_1M False It’s extremely efficient; the numbers in the range aren’t actually generated, instead the … Read more
