I am trying to do a reverse String problem in C and I am aware that there are other ways to do this but I am confused as to why the following solution is not working. (I'll put the output below)

/*Write a function reverse (s) that reverses the character strings. Use it to write a program that reverses its input a line at a time*/#include <stdio.h>#define MAXLENGTH 1000int ngetline(char s[], int lim);void nreverse(char s[], int index);main(){    int len;    char line[MAXLENGTH];    while(len = ngetline(line, MAXLENGTH) > 0)    {        printf("length: %d\n", len);        nreverse(line, len);    }    printf("%s", line);    return 0;}int ngetline(char s[], int lim){    int c;    int i;    for(i = 0; i <  lim -1 && (c = getchar()) != EOF && c != '\n'; ++i)    {        s[i] = c;    }    if(c == '\n')    {        s[i] = c;        ++i;    }    s[i] = '\0';    printf("i: %d\n", i);    return i;}void nreverse(char s[], int len){    int i, backIndex;    int halfway;    char temp;    backIndex = len - 2;    halfway = backIndex / 2;    for(i = 0; i <= halfway; ++i)    {        printf("In the for\n");        temp = s[i];        s[i] = s[backIndex];        s[backIndex] = temp;        --backIndex;    }}

Here is the output:

./reverseStringentering whileString to be Reversedi: 22length: 1

As you can see in the code, I set the length equal to the function ngetline() which returns i. But then when I print/try to get length, it returns 1. Does anyone know why this is happening? Thanks.

I'm trying to write a program that reads a text from a file (only strings) and reverse it. The following code does that, but it doesn't take into account spaces between words:

#include<iostream>#include<vector>#include<fstream>using namespace std; int main(){    ifstream file("file.txt");    char i;    int x;    vector<char> vec;    if(file.fail()){        cerr<<"error"<<endl;        exit(1);    }    while(file>>i){        vec.push_back(i);    }    x=vec.size();     reverse(vec.begin(), vec.end());    for(int y=0; y<x; y++){        cout<<vec[y];    }    return 0;}

If the text on the file is "dlroW olleH", the program would print out "HelloWorld". What can I do so that it prints "Hello World" (with the space between both words)?

I have this function here that will print a string until it gets to the last character. The thing is I need it to do the opposite of that.

Instead of 'abc' printing 'abc, ab, c' I need it to print 'c, bc, abc'.

Thank you!

def reverse(string):  if len(string) == 0:    return string  else:    print(string)    return reverse(string[1:])

I have two strings. The first is normal string, the second I want to be a reversed string like first one, but in the console I didn't get the look of like first one listed by commas. How can I fix that ?

Normal string -

Revered string -

window.onload = function(){inputBox = document.getElementById("myText");btn = document.getElementById('sub');btn.addEventListener("click",function(event){event.preventDefault();    findPalindromes(inputBox.value);   });    str = inputBox.value;    function findPalindromes(str) {        var words = str.split(" ");            for (var i = 0; i < words.length - 1; i++) {                words[i] += " ";            }        console.log(words);        var newString = "";            for (var i = words.length - 1; i >= 0; i--) {                newString += words[i];            }        console.log(newString);     }} 

So I got stuck on a coding challenge that I almost knew the answer too. And I think I have to use the subString call in Swift 4 to get it 100%. I want to reverse every OTHER word in a string, but ignore or keep the punctuation in its original place( index ).

var sample = "lets start. And not worry about proper sentences."func reverseString(inputString: String) -> String {    let oldSentence = sample.components(separatedBy: " ")    var newSentence = ""    for index in 0...oldSentence.count - 1 {        let word = oldSentence[index]        if newSentence != "" {            newSentence += " "        }        if index % 2 == 1 {            let reverseWord = String(word.reversed())            newSentence += reverseWord        } else {            newSentence += word        }    }    return newSentence}reverseString(inputString: sample)

And this would be the expected output.

"lets trats. And ton worry tuoba proper secnetnes."

Notice the punctuation is not reversed.
