Hey @Learning_bunny
first of all, in line no 24 of your code, you need to write
abc+=str[0];
instead of
abc[0]=str[0];

also, in your dupstr function you need to pass string abc by referrence so that the changed value remains between the subsequent calls (because you’re changing it’s value in every call). Try doing these changes

i have tried doing it lke abc+=str[0] but thats not working then i have changed it to abc[0]=str[0]

#5

and when i passed the string abc with reference then it is showing error in return abc; in line no 7
