一直说double int pt函数之前有一个预期的表达式

 #include <stdio.h>
 int pt (int a, int b)
 {
    int c, result;
      c = (a * a) + (b + b);
        result = double sqrt (double c);
   return result;
 }
 int main (void)
 {
     int d, e, f;
     int pt (int a, int b);
     printf("type enter after input of the two legs");
     scanf("%i", &d);
     scanf("%i", &e);
     f = pt (d,e);
     printf("the hypotenuse is %i", f);
     return 0;
 }
