Finding the max/min value in an array of primitives using Java
... class MinMaxValue {
public static void main(String[] args) {
char[] a = {'3', '5', '1', '4', '2'};
List b = Arrays.asList(ArrayUtils.toObject(a));
System.out.println(Collections.min(b));
System.out.println(Collections.max(b));

String literals: Where do they go?
... dependent on your platform and could change over time), just use arrays:
char foo[] = "...";
The compiler will arrange for the array to get initialized from the literal and you can modify the array.

...point.
It has one of these two signatures:
int main();
int main(int argc, char* argv[]);

And then, to make it easier to switch between Unicode (UTF-16) and their multibyte character...

In C, how should I read a text file and print all strings

putchar(c);
fclose(file);
}
c is int above, since EOF is a negative...
