How to use <ctype.h> headerfile?

Question

It shows \302 error.

Answer 1

Use <cctype> for a c++ program not <ctype.h>.
I usually get the "\302" error when I copy and paste into "code playground" (probably pasting some "invisible" characters), so just back-space each line to left-had-side of the code pane then re-indent/re-align.

It's <cctype> not <ctype) ...although it's not actually used in the code posted.

@Mohan 333....
Separate your input from your "sort" routine i.e:-
for(i=0; i<5; i++)
{
cout<<" ";
cin>>str[i];
}

for(i=0; i<5; i++)
for(j=1; j<5; j++)
{
if(strcmp(str[j-1],str[j])>0)
{
strcpy(t,str[j-1]);
strcpy(str[j-1],str[j]);
strcpy(str[j], t);
}
}
