How can I compare each element of the string with the rest of the string?

Question

For example :
string "hello"
compare string[0] with the rest ( " ello " )
then string [1] with ( " llo ")

I mean comparing one symbol with each symbol of the rest string

Answer 1

#include <iostream>
#include <string>
#include <cctype>
#include <cstring>

using namespace std;

int main() {
string word;
cin>>word;

int len = word.length();
for(int i=0;i<len;i++){
for(int j=i+1;j<len;j++){
if(word[i]==word[j]){
cout<<word[i]<<" at i = "<<i<<" matches with "<<word[j]<<" at j = "<<j<<endl;
}
}

}

return 0;
}

Answer 2

your attempt?

you will need nested for loop for this.
the outer loop will deal with "h' and the inner for loop will deal with "ello" and so on.

post your code for better view.

thx for help

Answer 5

I had an idea to make a loop with a counter that resets if the character is equal to the character

Answer 6

#include <iostream>
#include <string>
#include <cctype>
#include <cstring>

using namespace std;

int main() {
string word;
cin>>word;
int dejcnt;int elcnt;
int len = word.length();
for(int i=0;i<len;i++){

dejcnt += 1;
if(word[i]==word[dejcnt])
{
dejcnt = 0;
elcnt += 1;//counter of comparings;

}

}

return 0;
}
