Where is the mistake

Question

https://code.sololearn.com/c0H6gTW07mEA/?ref=app here I did a code to convert to uppercase using function and pointers. I don't know what I am missing?

Answer 1

C++ is strictly typed, means you have to define what is *lower1* and *lower2* inside main before using them.

edit: Same is with str1 and str2 in your function which are undeclared and uninitialised anywhere

Answer 2

Also while calling the function capit() remove those single quotes from arguments ( I don't know why you put it there at first place )

edit : in function defination, both of the parameters have same name which will result in ambiguity

Answer 3

Oh okay I get it now. Will try thanks Arsenic ☺️
