Need the program to read txt file with bunch of characters
After reading it should show most commonly used character and least common

using namespace std;

const int SIZE = 50;
char line[SIZE];

void mostFrequent(char *, int);

int main()
{
ifstream inputFile;

//Open the file
inputFile.open("c:/letter_count.txt");
if (inputFile.fail())
{
cout << "Error opening file.\n";
}
else
{
// Process the file.
}

char string[SIZE];
int length;

cin.getline(string, SIZE);
length = strlen(string);
char *stptr = string;
mostFrequent(stptr, length);

cin.get();

return 0;
}

void mostFrequent(char *ptr, int length)
{
int array[256] = { 0 };
int i;
int index = 0;
char ch;

for (i = 0; ptr[i] != '\0'; i++)
{
if (ptr[i] != ' ')
++array[ptr[i]];
}
for (i = 0; i < 256; i++)
cout << array[i];
cout << endl;

int max = array[0];
for (i = 1; i < 256; i++)

{
if (array[i] > max)

{
max = array[i];
index = i;
}
}

cout << "The most common letter occurrences "

<< static_cast(index);

}

kata gayab ho C++ experts haru, help me with this code its not compiling

sigh!! kati desperate bhako bro..tait..and start using stackoverflow jeez.
I hope now you can figure out on how to do with file input...

string mostFrequent(string input)
{
int max = 0;
int count = 0;
string mostOccuringChar;
for(char a=' ';a<='~';a++)

{
count = 0;
for(int i=0; i) {
if(input[i]==a)
count++;
}

if(count == max)
{
mostOccuringChar += a;
}

if(count>max)
{
max=count;
mostOccuringChar=a;
}
}

return mostOccuringChar;
}
int main()
{
cout <<"The letter that occurs most is: "<< mostFrequent("Hello World") < system("pause");
}

toupper A kata cha code ma bro,
and i added entire code and modified few but stilll no go
project due tomorrow cha

tyo file in c:/letter_count.txt read bhako nai chaina kina hola
error aihalcha

File read bhako chaina ? what error are you getting?
Paste you errors.
Here is info on how to read..it's not that hard..
http://www.cplusplus.com/doc/tutorial/files/

toupper kata cha?... why don't u add that?

not sure what am i doing wrong here bro, can you debug and see it for me please

Here, this works assuming your text file has no spaces between words..
So, modify accordingly.Seriously, can't sit here all day and debug your code.
#include "stdafx.h"

#include <fstream>

#include <iostream>

#include <fstream>

#include <string>

using namespace std;

string mostFrequent(string input)
{
int max = 0;
int count = 0;
string mostOccuringChar;
for(char a=' ';a<='~';a++)

{
count = 0;
for(int i=0; i) {
if(input[i]==a)
count++;
}

if(count == max)
{
mostOccuringChar += a;
}

if(count>max)
{
max=count;
mostOccuringChar=a;
}
}

return mostOccuringChar;
}


int main()
{
fstream f("C:\\test.txt", fstream::in );
string s;
getline( f, s, '\0');
string test = s;
cout << s << endl;
cout <<"Most frequent is-->"<< mostFrequent(test) <<endl;

thanks for your help alece bro

is it good ? can you take it from here now ?

As you can see its not showing the total number of most commonly used letter
Not sure what is happening, i will have to keep searching

this code actually compiles and shows right result, however i can't use this because it is using C-strings and C-strings functions

I am only allowed to use C++ string class and no global variables are to be used

did you even bother to read the comment i put at the top ? i told you it will work if the file has no spaces in it.. sigh!!

any thoughts on how to make it work including spaces in text? again i appreciate all your inputs and help

thanks much

alece any thoughts and btw after testing your code it shows all characters and does not calc total occurrence

Does anyone know how to convert c to c++ prg

There is one opening for c/c++ developer, is there anyone with solid experience on it? I can refer to a company. send me email at findmeitjob@gmail.com
