执行C程序，直至按Ctrl + C在终端打 [英] Execute C program till Ctrl+C hit in the terminal

问题描述

我写一个程序，反复做，直到按Ctrl + C的操作是通过在Linux终端的用户打。我编程在C任何想法如何，我可以实现这一点。

I am writing a program that repeatedly does an operation till Ctrl+C is hit by the user in the Linux terminal. I am programming in C. Any ideas how i can implement this.

我以为我的测试程序符合条件循环，但现在我希望把它只要按Ctrl + C被用户打和中断运行。

I have tested my program by using "for" loops with a condition but now i want to make it run as long as Ctrl+C is hit by the user and interrupted.

我在想什么是写做的while循环类似于​​下面的

What I was thinking was of writing a do while loop like the following

做{
   /的计算的/
}
而（Ctrl + C键是打不到）

do{ /Computation/ } while(Ctrl+C is not hit)

但我不知道如何检查由用户按Ctrl + C输入。

But i dont know how to check for the Ctrl+C input from the user.

任何建议将AP preciated。

Any suggestions will be appreciated.

感谢

推荐答案

一个信号陷阱会做的伎俩更清洁比spudd86的建议。这个例子可以显著得到改善，虽然

A signal trap will do the trick more cleanly than spudd86's suggestion. This example can be improved significantly, though.

#include <signal.h>
/* ... */

int execute;
void trap(int signal){ execute = 0; }

int main() {
    /* ... */
    signal(SIGINT, &trap);
    execute = 1;
    while(execute){
        /* ... */
    }
    signal(SIGINT, SIG_DFL);
    /* ... */
}
