Try the following:
#include<stdio.h>
#include<stdlib.h>
#include<math.h>
#define EPSILON 0.000001
/* Compares two floating point numbers for 'equality'
Returns 0 if left ~= right
Returns -1 if left < right
Returns 1 if left > right
*/
int fp_compare(double left, double right){
double diff = left-right;
if (fabs(diff) > EPSILON){
if (diff > 0){
return 1;
}else{
return -1;
}
}
return 0;
}
int main(void)
{
float num_a, num_b, num_c;
printf("Enter three integer(larger than zero):");
scanf("%f%f%f", &num_a, &num_b, &num_c);
printf("%f\n%f\n%f\n", 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)*/
if(fp_compare(num_a + num_b, num_c) <= 0 || fp_compare(num_a + num_c,
num_b) <= 0 || fp_compare(num_b + num_c, num_a) <= 0)
printf("can't!\n");
else
printf("can!\n");
system("pause");
return 0;
}
