Type casting: Computing average kids per family

Compute the average kids per family. Note that the integers should be type cast to doubles.
#include <stdio.h>

int main(void) {
 int numKidsA;
 int numKidsB;
 int numKidsC;
 int numFamilies;
 double avgKids;

numKidsA = 1;
 numKidsB = 4;
 numKidsC = 5;
 numFamilies = 3;

avgKids = (double) (numKidsA + numKidsB + numKidsC) / numFamilies;

printf("Average kids per family: %lf\n", avgKids);

return 0;
}
