Question

Hi i need a c++ program that can convert charactor into numbers

pseodocode

user input their name

for example john

every single charactor should have a value so it return correct result

eg:

j=2, o=1, h=7,n=2

and display these numbers

if you may need any question to ask me, i will be very happy to answer them.

Thanks!

example project close but not accurate

#include<iostream>
#include<string>
#include<exception>
#include <cstdlib>
#include<stdio.h>
#include<map>
#include <cctype>
#include<Windows.h>
#define INPUT_SIZE 8

using namespace std;

// Function to reverse a string
void reverseStr(string& str)
{
   int n = str.length();

   // Swap character starting from two
   // corners
   for (int i = 0; i < n / 2; i++)
       swap(str[i], str[n - i - 1]);
}
int main() {
   const std::string alpha = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";

   std::string text;
   std::cin >> text;

   // convert all lower case characters to upper case
   for (char& c : text) c = std::toupper(c);

   // sum up the values of alpha characters ('A' == 1, 'B' == 2 etc.)
   int sum = 0;
   for (char& c : text) // for each character c in text
   {
       // locate the character in alpha
       // http://www.cplusplus.com/reference/string/string/find/
       const auto pos = alpha.find(c);

       if (pos != std::string::npos) // if found (if the character is an alpha character)
                                   // note: non-alpha characters are ignored
       {
           const int value = pos + 1; // +1 because position of 'A' is 0, value of 'A' is 1
           sum += value;
           cout << sum;
       }
   }

Hi,

Please find the C++ program below:

There is some unnecessary function and code logic in the program.

There is no need to reverse a string. Iterate over the name and perform a lookup in the alpha array.

Calculation of sum of indices is not needed.

C++ program:

/******************************************************************************

C++ program.

#include<iostream>

#include<string>

#include<exception>

#include <cstdlib>

#include<stdio.h>

#include<map>

#include <cctype>

#define INPUT_SIZE 8

using namespace std;

int main() {

   const std::string alpha = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";

   cout << "Please enter your the name:";

   std::string text;

   std::cin >> text;

  

   // convert all lower case characters to upper case

   for (char& c : text) c = std::toupper(c);

   // Lookup character

   for (char& c : text) // for each character c in text

   {

      

       const auto pos = alpha.find(c);

       if (pos != std::string::npos) // if found (if the character is an alpha character)

                                   // note: non-alpha characters are ignored

       {

           const int value = pos + 1; // +1 because position of 'A' is 0, value of 'A' is 1

           // Print the character and the position

           cout << c << "=" << pos << endl ;

       }

   }

}

Can you let me know the output for j=2 , o=1 , h=7 and n=2 ?

Kindly let me know if you need more help on this.

Hope this helps.
