No this is not valid how ever you can do following: String[] name=new String[]{“h”, “e”, “l”, “l”, “o”}; or String name=new String(new char[]{‘h’, ‘e’, ‘l’, ‘l’, ‘o’}); solved Can we declare the reference variable as String for the char array? [closed]
string aS = “ABCDEFGHI”; char ch=”C”; int idx = aS.IndexOf(ch); MessageBox.Show(string.Format(“{0} is in position {1} and between {2} and {3}”, ch.ToString(), idx + 1, aS[idx – 1], aS[idx + 1])); This wont handle if your character is at position zero and some other conditions, you’ll have to figure them out. 2 solved C# get position … Read more
The variable n inside the function is distinct from the expression (or variable) supplied as an argument. As such, assigning to n inside the function will not affect any of the variables outside. (This is because Python is not Call By Reference.) Instead, use the return value, eg. def classifyInput(n): if n == “r”: return … Read more
Just another try on the code base of the question , #include<iostream> #include<string.h> using namespace std; int main() { string pass; string enc=”akdhigfohre”; string x = “”; string y = “”; cout<<“Enter new password: “; cin>>pass; cout<<“\n\nYour New Password is:” << pass<<endl; for(size_t i = 0; i < pass.size(); ++i){ x += pass.at(i)^enc.at(i%enc.size()); } cout<<“\n\nEncrypted … Read more
How do I create a C++ code that will allow a user to enter several percentage grades and then display the corresponding letter grade? solved How do I create a C++ code that will allow a user to enter several percentage grades and then display the corresponding letter grade?
Not only are you confusing the order or parametres in strcpy (it’s destination, then source, so strcpy(xstring, animalsarray[j][0]); would have it’s parametres inverted), you’re confusing a char with a pointer-to-char. xstring is a char, and you’re trying to use it as a string. If you want to set all the elements of the array to … Read more
You can use regular expressions from re module: import re s = “(‘-1259656819525938837′, 598679497)\t0.036787946” re.findall(r'[-+]?[0-9]*\.?[0-9]+’, s) % gives: [‘-1259656819525938837’, ‘598679497’, ‘0.036787946’] solved how to parse this string in Python? [duplicate]
To replace a backslash you have to escape it with another backslash. So in your example to replace \\ you have to escape each of them with backslash, so you can try this $replaced = str_replace(‘\\\\’, ‘\\’, $str1); solved How can I replace a blackslash character? [duplicate]
The assumption here is that you want to print the number a character repeats before it changes. You can try: public class MyClass { public static void main(String args[]) { String input = “aaaaaggff”; char c = input.charAt(0); int count = 1; System.out.print(c); for (int i = 1; i < input.length(); i++) { if (input.charAt(i) … Read more
You could try this. String nbr = input.nextLine(); int a=nbr.charAt(0)-‘0’; int b=nbr.charAt(1)-‘0’; int c=nbr.charAt(2)-‘0’; Also, you could use substring and parse the result Using Integer.parseInt int a=Integer.parseInt(nbr.substring(0,1)); //Contains the leftmost digit 2 solved How do I select the first, second, or third digit from a String containing three digits?
