用c在microsoft Visual C++2010版上编写学生信息管理系统要具体代码

抱歉，由于学生信息管理系统的具体需求和功能不同，代码也会有所不同，无法给出完整的具体代码。以下是一个简单的示例，供参考：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <windows.h>
#include <sql.h>
#include <sqlext.h>

// 定义数据库连接句柄和语句句柄
SQLHDBC hdbc;
SQLHSTMT hstmt;

// 连接数据库
int ConnectDB()
{
    SQLRETURN ret;
    SQLCHAR *dsn = (SQLCHAR*)"学生信息管理系统";
    SQLCHAR *user = (SQLCHAR*)"sa";
    SQLCHAR *password = (SQLCHAR*)"123456";
    ret = SQLAllocHandle(SQL_HANDLE_ENV, SQL_NULL_HANDLE, &henv);
    ret = SQLSetEnvAttr(henv, SQL_ATTR_ODBC_VERSION, (void*)SQL_OV_ODBC3, 0);
    ret = SQLAllocHandle(SQL_HANDLE_DBC, henv, &hdbc);
    ret = SQLConnect(hdbc, dsn, SQL_NTS, user, SQL_NTS, password, SQL_NTS);
    if (ret != SQL_SUCCESS && ret != SQL_SUCCESS_WITH_INFO)
    {
        printf("数据库连接失败.\n");
        return -1;
    }
    else
    {
        SQLAllocHandle(SQL_HANDLE_STMT, hdbc, &hstmt);
        return 0;
    }
}

// 关闭数据库连接
void CloseDB()
{
    SQLFreeHandle(SQL_HANDLE_STMT, hstmt);
    SQLDisconnect(hdbc);
    SQLFreeHandle(SQL_HANDLE_DBC, hdbc);
    SQLFreeHandle(SQL_HANDLE_ENV, henv);
}

// 查询学生信息
void QueryStudentInfo(char *name)
{
    SQLCHAR *sql = (SQLCHAR*)"SELECT * FROM Student WHERE Name = ?";
    SQLCHAR *pName = (SQLCHAR*)name;
    SQLINTEGER cbName = strlen(name);
    SQLBindParameter(hstmt, 1, SQL_PARAM_INPUT, SQL_C_CHAR, SQL_CHAR, 20, 0, pName, cbName, NULL);
    SQLExecute(hstmt);
    while (SQLFetch(hstmt) == SQL_SUCCESS)
    {
        SQLCHAR Id[20], Name[20], Gender[10], Age[10];
        SQLGetData(hstmt, 1, SQL_C_CHAR, Id, 20, NULL);
        SQLGetData(hstmt, 2, SQL_C_CHAR, Name, 20, NULL);
        SQLGetData(hstmt, 3, SQL_C_CHAR, Gender, 10, NULL);
        SQLGetData(hstmt, 4, SQL_C_CHAR, Age, 10, NULL);
        printf("%s %s %s %s\n", Id, Name, Gender, Age);
    }
}

// 添加学生信息
void AddStudentInfo(char *id, char *name, char *gender, char *age)
{
    SQLCHAR *sql = (SQLCHAR*)"INSERT INTO Student VALUES (?, ?, ?, ?)";
    SQLCHAR *pId = (SQLCHAR*)id;
    SQLCHAR *pName = (SQLCHAR*)name;
    SQLCHAR *pGender = (SQLCHAR*)gender;
    SQLCHAR *pAge = (SQLCHAR*)age;
    SQLINTEGER cbId = strlen(id);
    SQLINTEGER cbName = strlen(name);
    SQLINTEGER cbGender = strlen(gender);
    SQLINTEGER cbAge = strlen(age);
    SQLBindParameter(hstmt, 1, SQL_PARAM_INPUT, SQL_C_CHAR, SQL_CHAR, 20, 0, pId, cbId, NULL);
    SQLBindParameter(hstmt, 2, SQL_PARAM_INPUT, SQL_C_CHAR, SQL_CHAR, 20, 0, pName, cbName, NULL);
    SQLBindParameter(hstmt, 3, SQL_PARAM_INPUT, SQL_C_CHAR, SQL_CHAR, 10, 0, pGender, cbGender, NULL);
    SQLBindParameter(hstmt, 4, SQL_PARAM_INPUT, SQL_C_CHAR, SQL_CHAR, 10, 0, pAge, cbAge, NULL);
    SQLExecute(hstmt);
}

int main()
{
    if (ConnectDB() == 0)
    {
        QueryStudentInfo("张三");
        AddStudentInfo("2022001", "李四", "男", "20");
        CloseDB();
    }
    return 0;
}

以上示例中，使用了 SQL Server 数据库，通过 ODBC 连接方式连接数据库，并实现了查询学生信息和添加学生信息的功能。需要注意的是，以上代码仅供参考，实际开发中需要根据具体需求和功能进行修改和完善。
