Plz clear the two doubts.
1) how can I modify a letter of string. Like I did this,
Str="cat";
Str[0]='b';
But it said 'can't change character to string implicitly'. Is there any way to do it explicitly ?
2) is there any way to reverse a string thru a function coz I first tried to swap characters like I did in c but the doubt 1 👆stopped me
