can someone identify the error in my funtion?

[byronflds]

I continue to get error:

 try.cpp: In function `double trigSum(double, double)':
try.cpp:30: parse error before `)' token
try.cpp: In function `int main()':
try.cpp:62: parse error before `return'

on line 59 you are missing the semicolon.

[byronflds]

thanks. is there a program that you know of that can identify those kind of simple errors?

[LB]

Yes, there are many programs. They generally fall under the category of program known as C++ Compilers. Some give you better error messages than others.

[byronflds]

alright thanks ill look those up.

last thing: now that it compiles my answer always returns as 1, any clue why?


this is my updated code:

double trigSum(double num1,double num2)

double sum;

sum = cos(num1) + sin(num2);

return sum;
} 


int main()

double num1;
double num2;

return 0;
} 

[pogrady]

try using either fixed or setprecision, but not both.

[byronflds]

that didnt work.

compiler gives this error though:

warning: the address of `double trigSum(double, double)', will
always be `true'

[LB]

End of line 62:

<< trigSum << endl;

You're printing a function itself, not its return value. Try removing line 59 and actuall calling the function:

<< trigSum(num1,num2) << endl;

[fg109]

Replace trigsum in line 62 with line 59.

[byronflds]

that worked thanks to you all.
