#include <stdio.h>

int main(void) {
    int a=100;
    do{
        printf("insert a");
        scanf("%d",&a);
    }while(a<10);
    return (0);
}

我在Eclipse C \ C ++ IDE中编写了此代码，但没有用.

推荐答案

不正确.它实际上执行了一些操作:总是执行循环的第一次迭代，至少有一个插入a"输出到控制台(如果有的话；取决于项目配置)，其他则取决于您输入的a的值.当然，该代码几乎没有意义-您需要告诉我们您想首先实现什么.

Not true. It actually does something: first iteration of the loop is always executed, at least one "insert a" outputs to console (if one is available; it depends on project configuration), others depend on what value for a you are entering. Of course, the code makes little to no sense — you need tell us what did you want to achieve first.

如果您正在研究Windows，那么您可能会对此感兴趣: [

If you are working on Windows then this may interest you: "Eclipse console does not show output on Windows"[^].

我没有刷新.

这有效:

i was missing a flush.

This works:

...
printf("insert a");
fflush(stdout);
scanf("%d",&a);
...
