C语言作为一门历史悠久且应用广泛的编程语言，对于编程初学者来说是一个理想的起点。然而，仅仅学习理论知识是不够的，上机实践是提高编程技能的关键。本文将为你推荐一系列上机实践项目，帮助你快速提升C语言编程技能。

实践项目推荐

1. 贪吃蛇游戏

贪吃蛇是一个经典的入门级游戏项目，通过这个项目，你可以学习到控制台输入输出、循环、数组等基础概念。

代码示例：

#include 
#include 
#include 
#include 
int x, y, fruitX, fruitY, score;
int tailX[100], tailY[100];
int nTail;
enum eDirecton { STOP = 0, LEFT, RIGHT, UP, DOWN};
enum eDirecton dir;
void Setup()
{ dir = STOP; x = 20; y = 20; fruitX = rand() % 28 + 3; fruitY = rand() % 28 + 3; score = 0;
}
void Draw()
{ system("cls"); for (int i = 0; i < 27; i++) { for (int j = 0; j < 27; j++) { if (i == 0 || i == 26) { printf("#"); } else if (j == 0 || j == 26) { printf("#"); } else { if (i == x && j == y) { printf("O"); } else if (i == fruitX && j == fruitY) { printf("F"); } else { int ch = 0; for (int k = 0; k < nTail; k++) { if (tailX[k] == i && tailY[k] == j) { ch = 1; } } if (ch == 0) { printf(" "); } else { printf("o"); } } } } printf("\n"); } printf("Score:%d\n", score);
}
void Input()
{ if (_kbhit()) { switch (_getch()) { case 'a': dir = LEFT; break; case 'd': dir = RIGHT; break; case 'w': dir = UP; break; case 's': dir = DOWN; break; case 'x': exit(0); break; } }
}
void Algorithm()
{ int prevX = tailX[0]; int prevY = tailY[0]; int prev2X, prev2Y; tailX[0] = x; tailY[0] = y; for (int i = 1; i < nTail; i++) { prev2X = tailX[i]; prev2Y = tailY[i]; tailX[i] = prevX; tailY[i] = prevY; prevX = prev2X; prevY = prev2Y; } switch (dir) { case LEFT: x--; break; case RIGHT: x++; break; case UP: y--; break; case DOWN: y++; break; default: break; } if (x >= 27 || x < 0 || y >= 27 || y < 0) exit(0); for (int i = 0; i < nTail; i++) { if (tailX[i] == x && tailY[i] == y) exit(0); } if (x == fruitX && y == fruitY) { score += 10; fruitX = rand() % 28 + 3; fruitY = rand() % 28 + 3; } nTail++;
}
int main()
{ Setup(); while (1) { Draw(); Input(); Algorithm(); Sleep(10); } return 0;
}

2. 字符串处理工具

通过编写字符串处理工具，你可以深入了解C语言中的字符串操作，如复制、拼接、查找等。

代码示例：

#include 
#include 
void CopyString(char *dest, const char *src)
{ while (*src) { *dest = *src; dest++; src++; } *dest = '\0';
}
void ConcatenateStrings(char *dest, const char *src)
{ while (*dest) { dest++; } while (*src) { *dest = *src; dest++; src++; } *dest = '\0';
}
void FindString(const char *str, const char *toFind)
{ const char *p = str; const char *q = toFind; while (*p && *q) { if (*p != *q) { p++; q = toFind; } else { q++; } p++; } if (*q == '\0') { printf("Found '%s' in '%s'\n", toFind, str); } else { printf("'%s' not found in '%s'\n", toFind, str); }
}
int main()
{ char str1[100] = "Hello, world!"; char str2[100]; CopyString(str2, str1); printf("Copied string: %s\n", str2); ConcatenateStrings(str1, " and welcome."); printf("Concatenated string: %s\n", str1); FindString(str1, "world"); FindString(str1, "test"); return 0;
}

3. 学生成绩管理系统

构建一个简单的学生成绩管理系统，可以帮助你理解数据结构和文件操作。

代码示例：

#include 
#include 
typedef struct
{ int id; char name[50]; float score;
} Student;
void AddStudent(Student *students, int *count)
{ Student s; printf("Enter student ID: "); scanf("%d", &s.id); printf("Enter student name: "); scanf("%s", s.name); printf("Enter student score: "); scanf("%f", &s.score); students[*count] = s; (*count)++;
}
void DisplayStudents(const Student *students, int count)
{ printf("ID\tName\tScore\n"); for (int i = 0; i < count; i++) { printf("%d\t%s\t%.2f\n", students[i].id, students[i].name, students[i].score); }
}
int main()
{ Student students[100]; int count = 0; int choice; do { printf("1. Add student\n"); printf("2. Display students\n"); printf("3. Exit\n"); printf("Enter your choice: "); scanf("%d", &choice); switch (choice) { case 1: AddStudent(students, &count); break; case 2: DisplayStudents(students, count); break; case 3: break; default: printf("Invalid choice. Please try again.\n"); break; } } while (choice != 3); return 0;
}

4. 猜数字游戏

猜数字游戏是一个有趣的项目，可以让您体验到程序的互动性。

代码示例：

#include 
#include 
#include 
int main()
{ int number, guess, attempts = 0; srand(time(0)); number = rand() % 100 + 1; printf("Guess the number between 1 and 100:\n"); do { scanf("%d", &guess); attempts++; if (guess < number) { printf("Higher!\n"); } else if (guess > number) { printf("Lower!\n"); } else { printf("Congratulations! You guessed the number in %d attempts.\n", attempts); } } while (guess != number); return 0;
}

5. 井字棋游戏

井字棋是经典的游戏项目，通过这个项目您可以学习游戏逻辑的设计。

代码示例：

#include 
#include 
#include 
char board[3][3];
enum ePlayer { PLAYER_X, PLAYER_O };
enum eState { IN_PROGRESS, X_WON, O_WON, DRAW, INVALID };
enum ePlayer currentPlayer = PLAYER_X;
void InitializeBoard()
{ for (int i = 0; i < 3; i++) { for (int j = 0; j < 3; j++) { board[i][j] = ' '; } }
}
void DrawBoard()
{ printf(" %c | %c | %c \n", board[0][0], board[0][1], board[0][2]); printf("---|---|---\n"); printf(" %c | %c | %c \n", board[1][0], board[1][1], board[1][2]); printf("---|---|---\n"); printf(" %c | %c | %c \n", board[2][0], board[2][1], board[2][2]);
}
bool PlaceMark(int row, int col, enum ePlayer player)
{ if (board[row][col] == ' ') { board[row][col] = (player == PLAYER_X) ? 'X' : 'O'; return true; } return false;
}
enum eState CheckForWin()
{ for (int i = 0; i < 3; i++) { if (board[i][0] == board[i][1] && board[i][1] == board[i][2]) { if (board[i][0] == 'X') { return X_WON; } else if (board[i][0] == 'O') { return O_WON; } } } for (int i = 0; i < 3; i++) { if (board[0][i] == board[1][i] && board[1][i] == board[2][i]) { if (board[0][i] == 'X') { return X_WON; } else if (board[0][i] == 'O') { return O_WON; } } } if (board[0][0] == board[1][1] && board[1][1] == board[2][2]) { if (board[0][0] == 'X') { return X_WON; } else if (board[0][0] == 'O') { return O_WON; } } if (board[0][2] == board[1][1] && board[1][1] == board[2][0]) { if (board[0][2] == 'X') { return X_WON; } else if (board[0][2] == 'O') { return O_WON; } } for (int i = 0; i < 3; i++) { for (int j = 0; j < 3; j++) { if (board[i][j] == ' ') { return IN_PROGRESS; } } } return DRAW;
}
void SwitchPlayer()
{ currentPlayer = (currentPlayer == PLAYER_X) ? PLAYER_O : PLAYER_X;
}
void PlayGame()
{ InitializeBoard(); DrawBoard(); while (true) { int row, col; printf("Player %d, enter row and column: ", currentPlayer); scanf("%d %d", &row, &col); if (row >= 0 && row < 3 && col >= 0 && col < 3 && PlaceMark(row, col, currentPlayer)) { DrawBoard(); enum eState state = CheckForWin(); if (state != IN_PROGRESS) { if (state == X_WON) { printf("Player X wins!\n"); } else { printf("Player O wins!\n"); } break; } SwitchPlayer(); } else { printf("Invalid move, try again.\n"); } }
}
int main()
{ PlayGame(); return 0;
}
