void foo() {
int *c = "hello weakly typed C!";
}
192:/tmp deets$ gcc -c test.c
test.c: In function `foo':
test.c:5: warning: initialization from incompatible pointer type
So I wouldn't call C strongly typed....
The distinction is usually made on two axis: strong-weak and
static-dynamic. Python is a strong-typed, dynamic language. JAVA is
strong-typed static. And PHP is weakly-typed dynamic.
