接上文题目，解二，c++的c语言实现

#include <iostream>#include <string>#include <cstdio>#pragma warning(disable : 4786) //Disable warning messages#include <vector>#include <fstream>using namespace std;int main(int argc, char *argv[]){char map[20][20];char command[10];int pox = 0;int poy = 0;int direction = 270;int i, j;for (i = 0; i < 20; i++)for (j = 0; j < 20; j++)map[i][j] = '.';freopen("input", "r", stdin);while( scanf("%s", &command) != -1){if (strcmp(command, "FORWARD") == 0){map[poy][pox] = '*';int len;scanf("%d", &len);switch(direction){case 0:while( len-- > 0){if (pox == 19) break;pox++;map[poy][pox] = 'X';}break;case 90:while( len-- > 0){if (poy == 0) break;poy--;map[poy][pox] = 'X';}break;case 180:while( len-- > 0){if (pox == 0) break;pox--;map[poy][pox] = 'X';}break;case 270:while( len-- > 0){if (poy == 19) break;poy++;map[poy][pox] = 'X';}break;}}else{direction+=90;direction= direction%360;}};for (i = 0; i < 20; i++){for (j = 0; j < 20; j++){printf("%c", map[i][j]);}printf("/n", map[i][j]);}return 0;}
