Help to see if there has a problem, subject requirements are 3 are floating point Numbers in the input, use function respectively determine whether can form a triangle, triangle area is also expressed in function calculation

CodePudding user response:

P=(a + b + c)/2; First ABC hasn't enter, first it is wrong to calculate p
Secondly if the judge whether the else is wrong? Not on both sides and a triangle were greater than the third? That is I is 0, enter the if branch

Oh oh, crab crab, I change

Why or not, see

CodePudding user response:

J=red (a - b, c) & amp; & Red (a, c, b) & amp; & plus (b, c, a);

CodePudding user response:

T=area (a, p, p - p - b, p - c); Need in this way, not t=area (p, a - p, b - p, c - p).

CodePudding user response:

Fun

reference 5 floor response:

j=red (a - b, c) & amp; & Red (a, c, b) & amp; & plus (b, c, a);

Oh oh oh, too careless

CodePudding user response:

Fun

reference 6 floor response:

t=area (a, p, p - p - b, p - c); Need in this way, not t=area (p, a - p, b - p, c - p).

I think is right, but when playing too fast, you made a mistake

reference 6 floor response:

t=area (a, p, p - p - b, p - c); Need in this way, not t=area (p, a - p, b - p, c - p).
