I[i]=4(FR*FR+FI*FI);应改为 I[i]=4*(FR*FR+FI*FI);注意，C语言中乘号不可省略。
The following sample code long offset(long v) { if (!v) return 0; if (v > 0) return 1; if (v < 0) return -1; } produces warning: non-void function does not return a value in all control paths [-Wreturn-type] So does long offset(long v) {...
