long int即long,给人的感觉好像是长整型,但实际上,它和int一样,只有32位。cppreference给出的定义是—— int– basic integer type. The keyword int may be omitted if any of the modifiers listed below are used. If no length modifiers are present, it’s guaranteed to have a width of at least ...

In this program we are giving comment-line argument conversion to long long integer. Open Compiler #include <iostream> #include <string> using namespace std; int main(int argc, char * argv[]) { if (argc != 2) { cerr << "Usage: " << argv[0] << " <number>" << endl; return...
在计算机编程中,long 和 int 都是整数类型,用于存储整数值。它们之间的主要区别在于存储空间的大小和平台依赖性。存储空间大小:int:在大多数现代编程语言中,int 类型通常用于存储在内存中的整数值。其大小通常是32位(即4个字节),它可以存储的值的范围从 -2,147,483,648 到 2,147,483,647(...

Long.getLong() 与 Long.valueOf() 的区别 Long.getLong(String nm) 这个方法并不是 字面意思 把字符串转成long,看源码会发现它是获取系统属性,然后将值转成Long Long.valueOf(String s) 这个方法是将字符串转换成long 然后再转成Long...byte、short、int、long 最高位:0正数1负数 byte:可以取-128...
