[https://mp.weixin.qq.com/s/ydhK8HYuRD0lZazPsPxsvg] c/c++语言具备一个不同于其他编程语言的的特性,即支持可变参数。 例如C库中的printf,scanf等函数,都支持输入数量不定的参数。printf函数原型为 int printf(const char *format, …); printf("hello world");///< 1个参数printf("%d", a);///...

10. int const *pa;指向整型常量的pointer,可以修改pointer value,但不可以修改它所指向的value。int *const pb;指向整型的常量pointer,无法修改pointer value,但可以修改它所指向整型value。int const *const pc;pointer vale和指向的整型的value都不可被修改。const修饰的对象不变,上例前两个为:*pa和pb,也就是...

in these function calls. None is passed as a C NULL pointer, bytes objects and strings are passed aspointer to the memory block that contains their data (char * or wchar_t *). Python integers are passed as theplatforms default C int type, their value is masked to fit into the C ...

2、C语言传递参数均是以值传递(pass by value),另外也可以传递指针(a pointer passed by value)。3、不同的变量类型可以用结构体(struct)组合在一起。4、只有32个保留字(reserved keywords),使变量、函数命名有更多弹性。5、部份的变量类型可以转换,例如整型和字符型变量。6、通过指针(pointer),C语言可以容易的...
