#include<stdio.h>
#include<stdlib.h>
int main()
{
float num_a, num_b, num_c;
printf("Enter three integer(larger than zero):");
scanf("%f%f%f", &num_a, &num_b, &num_c);
if(num_a + num_b <= num_c || num_a + num_c <= num_b || num_b + num_c <= num_a)
printf("can't!");

printf("can!");
system("pause");
return 0;
