String compression

what is wrong with my code,can you modify it
int main(){
string s;
cin>>s;
string str;
str=s[0];
int count=1;
for(int i=1;i<s.length();i++){
char curr=s[i];
char pre=s[i-1];
if(curr==pre){
count++;
}
else{
if(count>1){
str=str+count;
count=1;
}
str=str+curr;
}
}
if(count>1){
str=str+count;
count=1;
}
cout<<str;
}

hi @dips123deepali_c25f140838182212
refer this https://ide.codingblocks.com/s/642772

why did you use the second if else condition in the code

hi @dips123deepali_c25f140838182212
i have used that if else to check the corner cases… it may be possible that the last character occurs only single time or it is repeating… so just to handle these cases i have used that… try to dry run on 2-3 test cases, u will get better insight…

hi @dips123deepali_c25f140838182212
is it clear now??
