Question

Hi,

I have here a program which count the occurrence of individual characters in a string. If more than one characters are the same and are next to each other (aka: Mazzuzu), you would get 1M, 1a, 2z, 1u, 1z, 1u. I was able to make it work to some extent, but it does not come out completely correct. I think it is a looping and variable issue, but if anything how can I fix it?

------------------------------------------------------------------------------------------C++ program

int main(int argc, char *argv[])

{

string i;

int y = 0;

string input_line;

char ii;

string last = "rWWWora";

for(int ii = 0; ii < last.size()-1; ii++)

{

if(last.at(ii)==last.at(ii+1))

{

y++;

}

else

y=1;

cout<< y<<last.at(ii)<<endl;

}

}

return 0;

}

----------------------------------------------------------------------current output:

1r
2W
3W
1W
1o
1r

------------------------------------------------------------------------------desired output: as an example, I only need 3W because I have 3 W's, which are next to each other.

1r
3W
1o
1r
1a

#include <iostream>
using namespace std;
int main(int argc, char *argv[])

{

string i;

int y = 0;

string input_line;

char ii;

string last = "rWWWora";

for(int ii = 0; ii < last.size()-1; ii++)

{

if(last.at(ii)==last.at(ii+1))

{

y++;

}

else{
if(ii==0){
    cout<<1<<last.at(ii)<<endl;
}
else{
    cout<< y<<last.at(ii)<<endl;
}
y=1;
}

}
cout<< y<<last.at(last.size()-1)<<endl;

return 0;
