这是一个复合语句吧，首先需要知道bits--这条语句的意思，他就是使变量bits的值自减一，而--放在变量的后面与其他的运算符复合时，先取到变量bits值，然后再自减一，所以这句的意思就是先然段bits是否大于0，如果大于0，就执行循环，否则跳出循环，不管跳不跳出循环,bits都会自减一。bits 是 函数...
int main() { int a,b,c; cin>>a>>b; c=a+b;cout<<c; return 0; } 当输入为“1 2”时,输出为( ) A. 1 B. 2 C. 3 D. 4 相关知识点: 试题来源: 解析 C 【详解】 本题考查的是C++语言。当输入为“1 2”时,即1和2分别a和b,执行c=a+b=3,最后输出c的值为3,故本题应选C。...
R语言 把整数转换为比特 - intToBits()函数 R语言中的 intToBits() 函数用于将一个整数转换成比特,即0和1。输出的长度是整数向量长度的32倍。 语法: intToBits(x) 参数: x: 整数或整数向量 例1 : # R program to convert an integer to bits # Calling the int
