例如说我要进入这个代码整块到一个命令:谈到的代码的整体结构成一条线用C
int k = 0;
for (k = 0; k < 50; k++)
{
sprintf(buf, "M LR 10 -10\n"); //We put the string "M L 10" into the string buffer.
write(sock, buf, strlen(buf)); //We send the buffer into the socket.
memset(buf, 0, 80); //Clear the buffer, set buffer to value 0.
read(sock, buf, 80); //Read from the socket to get the results.
int lme, rme;
sprintf(buf, "S MELR\n"); //sensor command to find ME values
write(sock, buf, strlen(buf)); //sends the buffer to the socket
memset(buf, 0, 80); //Clear the buffer, set buffer to value 0.
read(sock, buf, 80); //read from socket to get results.
sscanf(buf, "S MELR %i %i\n", &lme, &rme); //takes lme and rme values from results
printf(buf, "%3i %-4i\n", lme, rme);
//distance = 2 * (22/7) * r
}
for (k = 50; k < 51; k++)
{
sprintf(buf, "C RME\n"); //We put the string "C RME" into the string buffer to reset.
write(sock, buf, strlen(buf)); //We send the buffer into the socket.
memset(buf, 0, 80); //Clear the buffer, set buffer to value 0.
read(sock, buf, 80); //Read from the socket to get the results.
}
,使我只是改变{sprintf(buf, "M LR 10 -10\n");}
字符串的值即10
和-10
,其余的过程会自行执行:
例如,set_motor_speed(10 -10\n)
在主代码中会执行整个功能,该怎么做呢?
这是一个_really_基本问题,的排序更好地解决一个基本的编程教科书比在线问答网站。你在C中寻找的术语是“函数定义”,但如果你还不知道,那么你可能根本不应该用C语言编写代码 - 对于初学者来说,它太低级了。 – zwol 2013-02-14 14:30:09
如果只有C中有一种方式来反复执行某个'函数... ....呃,那只是一个管道梦。 – 2013-02-14 14:30:22
有时候我们甚至想要一个函数*不能被一次又一次地调用... – 2013-02-14 14:32:38
