关于输入的问题

Question

在oj上做题时，他要求按照这样输入

但是一回车它就会运行程序啊  怎么才能达到这种效果呢？

Answer 1

#include<stdio.h> void main() { int i,n; for(i=0;i<5;i++) { scanf("%d",&n); printf("第一种输入方式\n"); } printf("第一种输入方式结束，限定输入次数\n"); while(scanf("%d",&n)==1) { printf("第二种输入方式\n"); } printf("第二种输入方式结束，满足特定条件\n"); }

Answer 2

你需要灵活运用printf（）函数，别想太多：①  int main(){                                                        ② int main(){        int a,b,c,d;printf("请在每行输入一个数据：\n");                            scanf("%d",&a); printf("\n");printf("First:%d\n",scanf("%d"));                                 scanf("%d",&b); printf("\n");printf("Second:%d\n",scanf("%d"));                            scanf("%d",&c); printf("\n");printf("Third:%d\n",scanf("%d"));                                scanf("%d",&d); printf("\n");printf("Fourth:%d\n",scanf("%d"));                            printf("a=%d\tb=%d\tc=%d\td=%d\n",a,b,c,d);return 0;                                                                     return 0;}                                                                                 }建议使用第二种，第一种我也是突发奇想，不知道可不可以，不过重在尝试嘛...

如果限定输入次数就用for循环,不限定输入次数而是有某种特定情况就用while循环。
