//printf (" % d ", 1.0 * arr [I] + +/I).
Printf (" % lf, "1.0 * arr [I] + +/I). For a floating point value, using % d output is problematic,

Subjects were first, can pass the compilation besides,Don't defined illegal nested structure,
Since your status changed to int, using strncpy don't deal with it, or you change back to a character array,
