This answer is based on the assumption that you do proper handling of your pointers between the part where you allocate memory for 1 element each and where you try to reallocate the memory. This part // realloc to correct…
You can try the below code to convert string array to string public class JavaApplication20 { public static void main(String[] args) { // TODO code application logic here String test1 = “”; String[] test = {“this”,”this2″}; int length = test.length;…
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?…
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…
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…
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:”…
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…
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…
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…
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…
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,…
strcmp will not give you the number of characters matching in the given strings. Try the below code, It will give number of matching characters in the input strings. #include <string.h> int GetMatchingChars (const char *s1, const char *s2) {…
Explanation line by line: Striker=Track; Sets Striker to point to the memory of Track, so Striker[0] would be equals to Track[0]. Track[1]+=30; Increases the value of the second index of Track by 30 (Track[1] = 50). cout<<“Striker >”<<*Striker<<endl; *Striker is…
As mentioned in @Jhonny Mopp’s comment the primary problem is, that you don’t read a whole line here: cin>>line; it just reads up to the next whitespace delimiter. What you actually want is: getline(cin, line); This would read in the…
