Here is the code FINALLY!!!!!!! for WSQ08.

// Solving Problems with Programming
// Professor Ken Bauer

// Jorge Alejandro Flores and Ken Bauer

// Standard libraries
#include <string>
#include <iostream>
#include <algorithm>

using namespace std;

// `BigIntegerLibrary.hh’ includes all of the library headers.
#include “BigIntegerLibrary.hh”

/*
* This function receives a BigInteger n and checks if it is a palindrome
* Return true if n is a palindrome, return false otherwise
*/
bool is_palindrome(BigInteger n){
string str1= bigIntegerToString(n);
string str2=str1;
reverse(str2.begin(), str2.end());
return (str2==str1);
}
/*
* This function receives a BigInteger n and returns the value of n plus the inverse of n.
*/
BigInteger apply196(BigInteger n){
string str1= bigIntegerToString(n);
string str2=str1;
reverse(str1.begin(), str1.end());
return n+ stringToBigInteger(str1);// you need to replace this with code that works
}

/*
* Your main program goes below and should use the two functions above
*/
int main() {
int nl=0;
int pal=0;
int l=0;
BigInteger n;
int low, up;

cout << “Give me the value of your lower bound” << endl;
cin >>low;
cout << “Give me the value of your upper bound” << endl;

for(int i=low; i<=up; i++){
n=i;

if(is_palindrome (n)==true){
pal=pal+1;
}
else {
int count=0;
bool lych= true;
while (count<=30){

lych=false;
break;
}
else{
count=count+1;
}

}
if (lych){
l=l+1;
}
}
}

cout<<“The analyzed numbers goes from “<<low;
cout<<” to “<<up<<endl;
cout<<“There are “<<pal;
cout<<” palindromes”<<endl;
cout<<“There are “<<l;
cout<<” lychrel numbers”<<endl;
cout<<“There are “<<nl;
cout<<” non-lychrel numbers”<<endl;
return 0;
}

I tried to do it for like 2 months and after a lot of explanations and time I finally did it. Thanks to everyone for your explanations! Ilysm. Here I used like a lot of mastery topics

My code is:

#include <iostream>

#include <fstream>

#include <string>

using namespace std;

int main()

{

string line;

int charCount, lineCount;

ifstream infile;

infile.open(“file.txt”);

charCount=0;

lineCount=0;

if (infile.is_open())

{

while( getline (infile, line))

{

lineCount++;

charCount += line.length();

}

}

cout<<“Number of characters: “<<charCount<<endl;

cout<<“Number of lines: “<<lineCount <<endl;

infile.close( );

return 0;

}

This program analyzes a file and returns the total of characters and the total of lines. I made this code with help from youtube videos and some other blogs.  Here I used #masterytopic21 because I read information from a file.

#include <iostream>
#include <string>
using namespace std;

int countChars(string userInput, char theChar){

int countChars = 0;

for (int i = 0; i < userInput.size(); i++)
{
if (userInput[i] == theChar)
{
++ countChars;
}
}
return countChars;
}

int main() {
string userInput;
char theChar=’a’;

cout<<“This program will tell you the number of ‘a’ inside your sentence”<<endl;
cout<<“Please type ‘:)’ followed by the sentence you want to analyze.”<<endl;
cin>>userInput;
getline(cin,userInput);

cout<<“Your sentence was “<<userInput<<endl;

cout<<“The number of “<<theChar <<” inside “<<userInput<< ” is: “<< countChars (userInput, theChar)<<endl;

return 0;
}

I’ve been 3 weeks or so trying to figure out how to make the “yosoy169” file and finally making something that runs reliefed me for like 5 seconds. This program was kinda hard too but not impossible. #quizweek10 #banana #kenbauer #masterytopic19 #masterytopic20 #masterytopic21
