Use the point_t data type. Define a new function

void read_point(point_t *p1);

that will read in from the user three floating point numbers into

the point_t. Declare two point_t variables in main, and use the read_point

function to read in values to them. Define a

new function

float distance(const point_t *p1, const point_t *p2);

that should compute the euclidean distance between the two points

and return the result. Use the sqrt function that is in math.h

Your main function should call this

function to determine the distance between the two points and should

then print the result.
