Netbeans代码默认为灰色 [英] Netbeans code becoming grey in colour by default

问题描述

#else

static double prev_value = 0.0;    // this lines becomes grey

// CLOCK_MONOTONIC represents the absolute elapsed wall-clock time 
//since 
// some arbitrary, fixed point in the past. It isn't affected by 
//changes in 
// the system time-of-day clock.

int r = clock_gettime( CLOCK_MONOTONIC, &t );   // this line also 
 // become grey  

#endif   

if ( r < 0 ) 
{
    // gettime can fail, so we need to do a check and possibly 
    //print error

    fprintf(stderr, "%s\n", strerror(errno)); 


 // On error return previous time


    return prev_value;   // Compiler throws an error that it could not 
                         // resolve the identifier prev_value 

}

推荐答案

是的，因为它位于if / else / end子句的'false'部分内，因为你可以清楚请参阅上面的代码。请参阅＃if，＃elif，＃else和#endif Directives（C-C ++） [ ^ ]。

Yes, because it is inside the 'false' section of an if/else/end clause, as you can clearly see in your code above. See #if, #elif, #else, and #endif Directives (C-C++)[^].
