This gives error:
int len;
scanf("%d",&len);
char str[len]="";
This also gives error:
int len=5;
char str[len]="";
But this works fine:
int len=5;
char str[len]; //so the problem lies with assignment not declaration

For a function that returns an int and takes a char you would do
typedef int (*functiontype2)(char);
and to use it
int dosomethingwithchar(char a) { return 1; }
functiontype2 func2 = &dosomethingwithchar
int result = func2('a');

What does the restrict keyword mean in C++?
... saved, as mentioned by supercat and michael.
Consider for example:
void f(char *restrict p1, char *restrict p2, size_t size) {
for (size_t i = 0; i < size; i++) {
p1[i] = 4;
p2[i] = 9;
}
}
Because of restrict, a smart compiler (or human), could optimize that to:
