Hello everyone.

I'm trying to write a program where a user will enter a set of x,y coordinates and the program will sort them based on their distance from the origin using sqrt (x*x + y*y). The x and y coordinates each go into their own array, but are supposed to be sorted in one function.

This is what i have so far.

When I try to build this I get the following errors:Code:#include <stdio.h> #include <math.h> #define MAX_LIST_SIZE 10 float calc_z (int x, int y); void sort_xy (int x[], int y[]); int i,j,hold, choice, coordNumber; int x[MAX_LIST_SIZE], y[MAX_LIST_SIZE]; void main () { while (1) { printf ("Enter (1) to run (2) to quit: "); scanf ("%d", &choice); if (choice == 2) return; else { printf("How many coordinates do you want to enter in: "); scanf ("%d", &coordNumber); for (i = 0; i < coordNumber; i++) { printf ("enter x,y: "); scanf ("%d,%d", &x[i], &y[i]); } void sort_xy (int x[], int y[]); for (i = 0; i < coordNumber; i++) { printf("%d %d\n", x[i], y[i]);} } } } void sort_xy (int x[], int y[]){ for (j=1; j<coordNumber; j++){ for (i=0; i < coordNumber-1; i++){ /* VV Problem here probably VV*/ if (float sqrt(x[i]*x[i]+y[i]*y[i]) > float sqrt(x[i+1]*x[i+1]+y[i+1]*y[i+1])) { hold= x[i+1]; x[i + 1]=x[i]; x[i] = hold; }}}}

error C2061: syntax error : identifier 'x'

: error C2059: syntax error : '>'

error C2143: syntax error : missing ';' before '{'

I have tried using another function to figure out the distance, but I couldn't figure out how to incorporate it into the sorting one.

If someone could point this noob in the right direction it would be greatly appreciated.
