Editing Logic error (section)

==Examples==

This example function in [[C (programming language)|C]] to calculate the [[Arithmetic mean|average]] of two numbers contains a logic error. It is missing parentheses in the calculation, so it compiles and runs but does not give the expected answer due to [[Operator precedence in C|operator precedence]] (division is evaluated before addition).
<syntaxhighlight lang="c">
float average(float a, float b)
{
    return a + b / 2;  // should be (a + b) / 2
}
</syntaxhighlight>
