Error: "expected '(' before string constant"

c

Solution

`extern "C"` is not valid C (it's only valid in C++). Just remove it if you're working in pure C.

Problem

Working on computing the geometric mean of values in an array The function should compute the geo mean correctly, but i'm getting a weird error message ``` #include <stdio.h> #include <stdint.h> #include <math.h> extern "C" double geomean(double myarray[], int count) ////error here, expected '(' before string constant { double geomean = 1; double root = (1/(double)count); int i; for(i = 0; i < count; i++) { geomean = geomean * myarray[i]; } geomean = pow(geomean, root); return geomean; } ```
