// removal of duplicate character form a given string
#include <string.h>
#include <stdio.h>

int main()
{
char os[30];
char ds[20];
int i=0,j=0, c;

printf("Enter string\n");
while ((c = getchar()) != '\n')
os[i++] = c;
os[i] = '\0';

ds[0] =os[0];
ds[1] = '\0';
i = 1;
while ( os[i] != '\0'){
j = 0;
while (ds[j] != '\0') {
if (ds[j] == os[i])
break;
else
j++;
}
if (ds[j] == '\0') {
ds[j] = os[i];

//using the std::string class from namespace std.

#include<iostream>
using namespace std;

int main()
{
string myStr;

cout<<"enter new string.";
getline(cin,myStr);
cout<<"entered value is "<<myStr;

char ch;
bool m=false;

string newStr;
newStr.resize(1);
int k=0;
for(int i=0;i<myStr.length();i++)
{
ch=myStr[i];
for(int j=0;j<k+1;j++)
{
if(ch!=newStr[j]) m=false;
else { m=true; break;}
}
if(m==false)
{
newStr.resize(newStr.size()+1);
newStr[++k]=ch;
