Thread: What's wrong?

The only thing wrong at compile time is the lack of a return statement:

Code:

#include <string>
#include <cmath>

using namespace std;

inline float tang(string A_O_Aj, float angle, float opposite, float adjacent)
{
    float x = 0;

    if(A_O_Aj == "A")
    {
        x = opposite / adjacent;
        x = atan(x);
        x = x * (180 / 3.141592);
        return x;
    }

    if(A_O_Aj == "O")
    {
        x = angle * (3.141592 / 180);
        return x;
    }

    if(A_O_Aj == "Aj")
    {
        x = opposite / (tan(angle * (3.141592 / 180)));
        return x;
    }
}

int main()
{
    tang("A", 1, 2, 3);
}

The compiler output:

Code:

test.cpp: In function 'float tang(std::string, float, float, float)':
test.cpp:29: warning: control reaches end of non-void function

If you disagree, post the smallest and simplest program that demonstrates the error, and post the exact error message.

Which line number?
And which line of your code is that?
