An Exercise Using Pointers in C

Given the following Point Struct Create 5 points and chain them together using the next pointer, then print them out using a while loop.

Struct Position { int x; int y; point *next;

}

int main ( int argc, char **, argv) {

position a; a.x = 100; a.y = 200;

position a2; a2.x = 1000; a2.y = 2000; a2.next = NULL; a.next = &a2;

position a3; a3.x = 10000; a3.y = 20000; a3.next = NULL; a2.next = &a3;

position a4; a4.x = 100000; a4.y = 200000; a4.next = NULL; a3.next = &a4;

position a5; a5.x = 1000000; a5.y = 2000000; a5.next = NULL; a4.next = &a5;

position aa = &a;

while (aa != NULL) {

printf("%d,%d\n", aa->x, aa->y); aa = aa->next;

}

}

That is my solution…:D

There is no #include

int main(int argc, char** argv) you had a random extra comma in there

all of your "position" declarations should be "point" because that's the name of the struct

return(0)

I did not run this through a compiler before posting this. Thank you for spotting those small errors and I might just change "point" to "position".
