I am getting some box as ouput instead pf numerical value....what changes should i do

#include
#include
using namespace std;

int main()
{
string s;
getline(cin,s);
int n=s.length();
int freq[26]={0};
for(int i=0;i<n;i++)
{
int digit=s[i]-‘a’;
freq[digit]++;
}
char cstring[100]={0};
int k=0;
for(int i=0;i<n;i++)
{
int digit=s[i]-‘a’;
if(freq[digit]!=0)
{

		cstring[k]=s[i];
		cstring[k+1]=freq[digit];
		freq[digit]=0;
		k=k+2;
	}
	
}
for(int i=0;cstring[i]!='\0';i++)
{
	cout<<cstring[i];
}

return 0;	
}

hey @angivanshikaangi, please share the code saved in Coding blocks ide as text gets mismatched here.

hey @angivanshikaangi, you are getting these boxes because you are storing int value in char array. Check line number 25.(cstring[k+1]=freq[digit]; ) . Make it cstring[k+1]=freq[digit] + ‘0’;

Moreover you approach is also not correct as it is printing wrong answer when same character occurs after gap.
example
input:
aaabbccbbds

your code’s output:
a3b4c2d1s1

but the expected output is:
a3b2c2b2d1s1
