C++制表符"\t”的用法

#include <iostream>
int main()
{
 std::cout << "The size of a short int is:\t" << sizeof(short int) <<"\n";
 std::cout << "The size of an int is:\t" << sizeof(int) << "\n";
 std::cout << "The size of a long int is:\t" << sizeof(long int) << "\n";
 std::cout << "The size of a char is:\t" << sizeof(char) << "\n";
 std::cout << "The size of a float is:\t" << sizeof(float) << "\n";
 std::cout << "The size of a double is:\t" << sizeof(double) << "\n";
 std::cout << "The size of a bool is:\t" << sizeof(bool) << "\n";
 return 0;
}

 

 

显示出来却是：

The size of a short int is:     2
The size of an int is:  4
The size of a long int is:      4
The size of a char is:  1
The size of a float is: 4
The size of a double is:        8
The size of a bool is:  1
Press any key to continue

 

制表符没起作用吗？

追问：问题是，在每一行我都输入了“\t”，但是貌似只有几行有效果，其它行都没效果。

答案：
这不是已经起了效果了么，相当于你输入文字时候按了键盘上的tab键啦。
