The realization of the Cheng of the Linux line play the alphabet function

Objective

Recently began my thread learning, a slight gain, compared with the process, its multi-threaded simultaneous execution of the code segment features, it is a huge charm.
Stealing that programming learning, such as martial arts training, learning moves but two strokes really should not, so do a dozen letters, practice.

Main ideas

The most important place to play the letter function is "the letter keeps falling, if the corresponding key is pressed, the letter disappears, and a new letter appears above, repeat this process".
In short, it is the need to accept user keys in real time when outputting information to the screen , which is in conflict with the sequence of programming we learned earlier, but threads can solve this problem.

Process Brief

1. Close the input buffer and enter the echo.
2. Create a global variable, save the character to be displayed, and its coordinate position.
   Initializes the string, assigns it a random number, and assigns a value to its coordinates.
3. Create a new thread, the function of the thread corresponding function for the clear screen after the output characters in their respective coordinates and after each loop, give the x-coordinate value of each of the sub-characters plus a
4. In the original thread also set a loop, real-time receive user input, according to user input to determine whether the key is correct, if correct, re-assign the character randomly, otherwise re-enter.
5. Real-time judgment, if there are letters over the lower bounds, if any, then the program ends
6. Input buffers and input echo

Code

#include <stdio.h>#include <string.h>#include <stdlib.h>#include <pthread.h>#include <unistd.h>#include <time.h>Charstr[Ten];Charx[Ten];Chary[Ten];int* Thread () {intI while(1) {System ("Clear"); for(i=0;i<Ten; i++) {//output character at corresponding coordinates            printf("\033[%d;%dh%c\n", X[i],y[i],str[i]);        x[i]++; } Sleep (1); }returnNULL;}intMain () {pthread_t thid;intICharC=' + '; System"Stty-icanon"); System"Stty-echo"); Srand ((unsigned) time (NULL)); for(i=0;i<Ten; i++) {//String initializationStr[i] =' A '+ rand ()% -; X[i] =2; Y[i] = i*3+3; }//Create thread    if(Pthread_create (&thid,null, (void*) Thread, (void*) &i)! =0)    {printf("error!\n");Exit(1); } while(1) {c = GetChar ();if(c!=' + ')        { for(i=0;i<Ten; i++) {if(c = = Str[i]) {Str[i] =' A '+rand ()% -; X[i] =2; C=' + '; Break; }            }        } for(i=0;i<Ten; i++) {if(x[i]>= -)            { Break; }}} System ("Stty Icanonon"); System"Stty echo");return 0;}

Conclusion

Because the main purpose is to learn the thread, so the basic function of the alphabet can not be implemented after the implementation of other functions.
After all, is a beginner, what is wrong, welcome criticism.
