Question Details:

1 #include <iostream>

2 using namespace;

3 /* This program indicates if a triangle is a

4 valid triangle or not. A triangle is a

5 valid triangle, if the sum of any of it’s

6 two sides is greater than the third one.

7 /*

8 int read_numbers(double& , double& , double& );

9 bool triangle (double a, double b);

10 void read_numbers(double& x, double& y, double& z)

11 {

12 cout << "\nEnter the first number: ";

13 cin >> x;

14 cout << "\nEnter the first number: ";

15 cin >> y;

16 cout << "\nEnter the first number: ";

17 cin << z;

18 }

19 int main()

20 {

21 double x, y = 0 , z;

22 bool true_or_false;

23 read_numbers(x, y);

24 If(!x || !y || !z)

25 cout << "Invalid input.";

26 else if(triangle(x, y, z))

27 cout << "this a valid triangle.";

28 else

29 cin << "this is not a valid triangle. ";

30 return;

31 }

32 bool triangle (double x, double y, double z)

33 {

34 if ( x + y > z && x + z > y && z + y > x)

35 return true

36 }

There are ten compiler errors. can you someone help me with them. thanks.. i have found 7 of them. will rate lifesaver.. need to study for exam.

Line 2: std is missing

Line 10: void should be int

Line 17: Should be cin >> z

Line 24: “If” should be “if”

Line 29: cin should be cout

Line 30: Should be return 0;

Line 35: Needs semicolon
