How do I check for a null operator to stop the floating point exception when trying to divide by the last number of the array(0)?

#include

int main() { int out = 0, tot = 0, cnt = 0; int val[] = {5, 54, 76, 91, 35, 27, 45, 15, 99, 0};

while(cnt < 10) { out = val[cnt]; tot = tot + 0xffffffff/out; cnt++; }

printf(" Total = [%d] ", tot); return 0; }
