@Bogdan/Prashant. 5: void main() is not valid c++

Answer 3

So where is that code? In order to help you, we need to know what you did :)

Answer 4

@jay - you're right. I corrected that when running the code, but forgot all about it when posting :))

Thanks!

Answer 5

void main()
{
char ch;
cout<<"input ";
cin>>ch;
if (isupper(ch)1)
{ch=tolower(ch);
cout<<"\n"<<ch;
}
else if (islower(ch)=1)
{ch=toupper(ch);
cout<<"\n"<<ch;
}getch()
}

Answer 6

Indentation is key - if you don't indent your code properly, you WILL miss things....

Here is the same code, indented:

void main()
{
char ch;
cout<<"input ";
cin>>ch;
if (isupper(ch)1) {
ch=tolower(ch);
cout<<"\n"<<ch;
}
else if (islower(ch)=1) {
ch=toupper(ch);
cout<<"\n"<<ch;
}
getch()
}

Running it, I get no error about "if statement missing". However, there are several issues:
1) isupper() and islower() return a boolean value, so there is no need to compare them with 1. Just use if(isupper(ch)){}
2) the comparison operator is "==", not "=" (so "islower(ch)=1" will not work)
3) getch() will not work in the code playground on sololearn
4) you need a ; after getch()
