char *str=&lpate;
for (int i=0 : i<strlen(str) : i++)
{
if (islower(*(str+i)))
toupper(*(str+i));
}#include <iostream>
#include <ctype.h>
#include <string>
using namespace std;
void makeupper (string& s)
{
int i = 0;
while (s[i])
{
s[i] = (toupper(s[i]));
i++;
}
}
int main ()
{
int i = 0;
string str = "It's 5 o'clock somewhere!\n";
makeupper(str);
cout << str;
return 0;
}
Maybe this will help:
Code:#include <iostream> #include <string> using namespace std; void makeupper (string& s) { int i = 0; while (s[i]) { s[i] = (toupper(s[i])); i++; } } int main () { int i = 0; string str = "It's 5 o'clock somewhere!\n"; makeupper(str); cout << str; return 0; }
EDIT: Damn, Virtuous beat me to it. I like mine better.
That and I dont remember if toupper() checks if a char is a lower case alpha. Probably does
Compiles and runs just fine.
Mostly because I couldn't remember how. I've been messing with Java for too long, and C++ is just different enough to throw me for a loop.
You need ctype.h in there too. Cant make it too easy for him though
Hey, I passed an argument by reference...
#include <iostream>
#include <ctype.h>
#include <string>
using namespace std;
int main ()
{
string str = "abc123\n";
str[0] = toupper(str[0]);
str[1] = toupper(str[1]);
str[2] = toupper(str[2]);
cout << str;
return 0;
}
I never been keen on pointers myself. The worst is a pointer to a pointer to a pointer.
Java is a great OOP language, because you are forced to use classes. In comparison C++ can be sloppy. I'm surprised that the OP's Computer Science Department hasn't switched over to Java. I know Rutgers has.

When I was doing my Computer Engineering undergraduate at Michigan State 95-99, they somewhat discouraged pointer use. I think for good reason too. You can get in a lot of trouble if you are not too careful. Pointers have their use, don't get me wrong, but it is not always clear what the code is attempting to do. I like my code clear and concise.
I think pointers can be a difficult concept to grasp but one absolutely necessary to being a good programmer. I nearly any language you work with you will be using pointers either explicitly (C) or indirectly (Java). How they are work is something that is important to understand to write efficient code.
In C/C++ arrays (x[]) , pointers (*ptr) and references (&ref) are all really pointers underneath.
Now I'm going off and confusing the new programmer
Sorry I'll try to stay on topic from now on.

. The problem with these, especially C++ is that the code can easily be obscured. You should see some of the code generated stuff from Simulink or Rhapsody.
