Array is a collection of elements which are of similar types. Array is very useful in C. Suppose we want to store 50 students marks then for this purpose we need to use 50 variable which is not possible and hard to manage so to avoid this situation we use array in which 50 students ...

Well, in C, the name of an array, is actually a pointer to the first element of the array.Confused? Let's try to understand this better, and use our "memory address example" above again. The memory address of the first element is the same as the name of the array:...
Pointers and arrays in C: Relationship between Arrays and Pointers Following 3 for loops are equivalent: Code: #include <stdio.h> #define N 5 int main() { int i, * ptr, sum = 0; int nums[N] = {1, 2, 3, 4, 5}; for (ptr = nums; ptr < & nums[N]; ++ptr) ...
按照The C Programming Language中介绍,这个表达式应该看成int (*p),也就是*p是个变量,它是一个int类型,与int v是等价的。*在变量前表示把当前的指针类型解析成它指向的数据类型,那么去掉*,就表示它是一个指针。 进一步说,就是,p是一个指针,*的作用是把p(指针)解析成它指向的数据,*p就是p指向的数据,类型...

可以进入到Arrays.toString里面看源码，因为c是二维数组，所以这里的a[i]就是一个数组，并不是一个实际的数。然后每次执行String.valueOf(a[i])方法。然后进入源码String类里面的valuefOf方法。在valueOf里面调用的是obj.toString()方法，这里返回的字符串格式就是你控制台输出的样式。
public static <T> void sort(T[] a, Comparator<? super T> c) Sorts the specified array of objects according to the order induced by the specified comparator. All elements in the array must be mutually comparable by the specified comparator (that is, c.compare(e1, e2) must not throw a...
指针作为 C/C++ 语言最强大的底层操作功能,它表现多少有些类似于变量。 首先,指针和变量一样,具有两个部分的属性,一个是关联类型属性,另一个是地址值。 其次,指针本身也可以变量一样占用内存,但是指针占用的内存是固定的,例如使用sizeof(char *)获取字符指针的大小,在 32-bit 平台里,指针本身占据了 4 个字节...
