[ad_1] 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 size for(int a = 0; a < word_nb; a++) { *(word_list + (word_nb-1)) = … Read more
[ad_1] 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; //System.out.println(“Length :”+length); for(int i=0; i<length; i++){ //System.out.println(test[i]); test1 += test[i]+”,”; } int len = … Read more
[ad_1] 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’}); [ad_2] solved Can we declare the reference variable as String for the char array? [closed]
[ad_1] 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 [ad_2] solved C# … Read more
[ad_1] 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”: … Read more
[ad_1] 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()); } … Read more
[ad_1] How do I create a C++ code that will allow a user to enter several percentage grades and then display the corresponding letter grade? [ad_2] 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?
[ad_1] 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 … Read more
[ad_1] 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’] [ad_2] solved how to parse this string in Python? [duplicate]
[ad_1] 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); [ad_2] solved How can I replace a blackslash character? [duplicate]
[ad_1] 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 … Read more
[ad_1] 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 [ad_2] solved How do I select the first, second, or third digit from a String containing three digits? [closed]
[ad_1] 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) { int len1; int len2; int count = 0; int minLen = 0; char *shortPtr … Read more
[ad_1] 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 the same as Striker[0], *Stirker+1 is the same as Striker[1] and so on. The … Read more
[ad_1] 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 whole input until you hit Enter. Regarding the rest of processing refer to that … Read more
