The Python int () function converts a given object to an integer or converts a decimal (floating-point) number to its integer part by truncating the fractional part. Example: In this example, we passed a string as an argument to the int () function and printed it.
The statement int&&a = 2; is in C++11 (and later) and refers to the way 'rvalue references' are declared. If you do just int& a = 2; the compiler will complain, since the literal value 2 is an rvalue, and 'normal' references cannot take rvalues as references.
1 Allocates, on the stack, space for [an array of] two int s. Populates [the array of] the two int s with the values 0 and 2, respectively. Declares a local variable of type int* and assigns to that variable the address of [the array of] the two int s.
p1 先与" []"结合，构成一个数组的定义，数组名为p1，int 修饰的是数组的内容，即数组的每个元素。 那现在我们清楚，这是一个数组，其包含10 个指向int 类型数据的指针，即指针数组。
Definition and Usage The int() function converts the specified value into an integer number.
int a=2; a*=2+3 C语言最后为什么运算结果是12。最好能解释的简单点，我是初学者a*=2+3先计算右侧加法, 于是是a*=5等效于a=a*5然后 带入aa=2*5=10;这个是不可能等于12的.
Int a, int b will hold value of whatever value the same assigned. When variable 'a' is created, it has a memory address and value assigned. The same description works equally well for int *a. The only difference is "the value stored in the variable is a pointer", rather than "the value stored in the variable is an integer". Pointers are values.

若有说明:int a [] [3]= {1,2,3,4,5,6,7定义二维数组时，若第一维不确定第二维确定，则数组必须初始化;初始化后数组中元素个数除以第二维大小加上1得到第一维大小;若第一二维全部确定，可以不初始化，默认元素全部为0;不允许第二维不定
