Question You are given two arrays of integers a and b. For each element of the second array bj you should find the number of elements in array a that are less than or equal to the value bj.Input T

int a;while(cin>>a){ ···}       这时如果从键盘输入的为int类型的数据，则“cin>>a”这条语句返回a的地址，因为a的地址在计算机中不为0，因此，遇到判断语句时，就判断”真“。当输入的数据类型不为int型时，其返回值为0,表示“假”。       关键这种判断条件对我们造成的困扰在于，但我们想在其后继续输入数据时，却无法输入。 例如：int a;
