Input and Output in C/C++ 1. 标准输入输出scanf()返回值为输入变量个数,终止输入使用Ctrl+z(等于输入EOF或-1)。1 2 3 4 5 6 7 8 #include<stdio.h> int main() { int x; while (scanf("%d", &x) == 1) { printf("%d\n", x); } return 0; }cin返回值为cin,终止输入使用Ctrl+z。
Programmers don’t need to write special input/output functions for each device (keyboard, disk, and so on). The program sees input/output as a continuous stream of bytes no matter where the input is coming from or going to. Every C stream is connected to a file. In this context, the...
