JavaScript is not currently enabled, but is required for full CodeSonar manual search and browse functionality.

If you are viewing this file in your hub's Web GUI, enable JavaScript in your browser: you will also need it for GUI functionality.

If you opened this file directly from disk, your browser may be directly suppressing JavaScript functionality: certain browsers perform this suppression on local files (but not files delivered by web servers) for security reasons.

If you access the manual through the hub's Web GUI, the functionality will not be suppressed because the hub is a web server.
Alternatively, your browser may allow you to explicitly disable the security setting that suppresses functionality. See the CodeSonar FAQ for more information.

例

関数 f() と g() は同じ内容で(インデントのみが異なります)、両方に対してこのワーニングが検出されます。インデントによって、g() 中の b(i) が if 文に含まれていると誤解し易くなっています。本体を明示的な括弧で囲むことにより、動作が明確になります。

void a(int p);
void b(int p);
void c(int p);

void f(int i){ 
    if (i > 5) /* 'Body Is Not Compound Statement' warning issued here */
        a(i);
    b(i);
    c(i);
}  

void g(int i){ 
    if (i > 5) /* 'Body Is Not Compound Statement' warning issued here */
        a(i);
        b(i);
    c(i);
}
