摘要: This paper provides formulas relating the number of faults or ``bugs'' to lines code and conditional jumps. A result is that there are, on average, about 21 bugs per KSLOC discoverable after successful compilation. major motivation for work presented here was determine if some published data suggest any relationship between level coding language employed (e.g., Jovial a ``high'' language) found. It shown appears not be function ``level'' employed. In addition, knowledge items such as size vocabulary (operator operand) used little consequence estimate bug content beyond based SLOC count.
