Question

How to deal with string manipulation in c++ without using built-in functions. how to return the array (1d or 2d) from functions in c++)?

Answer 1

String maniputlation can be done easily by using loops in C++

Just run the loop from index 0 until null is recieved

ex

for(int i=0;s[i]!='\0';i++)

//do what you want

To return the arrays we can use 1 of the 3 methods

1)Using dynamically allocated arrays - int* fun(int *arr) { return arr;}

2)using static array - int* fun(){static int a[100]; return a;}

3)using structures - use structure
