Syntax error : missing ';' before 'type'

Question

So i have this error:

Error 3 error C2143: syntax error : missing \';\' before \'type\' g:\\lel\\tommy\\tommy\\tommy.c 34 tommy

Answer 1

Are you compiling with c99 or c89?

The error appears to be because you are defining a variable within the body of the function (allowed in c99 not c89). Move double *ptr to the beginning of the function and then just assign ptr = mat->matrix; where the error now is.
