任何人都可以帮助我编写代码

void gotoxy(int, int);
void clrscr();
void dispMenu();

int main(void){
    int choice;

    choice = 0;
menu:
    dispMenu();
    scanf("%d", &choice);

    if(choice==1){
        clrscr();

        char name[100];

        printf("Please Input your Complete name: ");
        scanf("%[^\n]s", &name);

        printf("Your name is: %s \n", name);
    }

    getch();
    goto menu;
}

void dispMenu(){
    gotoxy(23,9);
    printf("List of C-Lang Activities\n");
    gotoxy(23,11);
    printf("1. Input Name");
    gotoxy(23,12);
    printf("2. (blank) \n");
    gotoxy(23,13);
    printf("3. (blank) \n");
    gotoxy(23,14);
    printf("4. (blank)\n");
    gotoxy(23,15);
    printf("5. (blank)\n");
    gotoxy(23,17);
    printf("Please Enter the Number of your choice: ");
}

void gotoxy(int x, int y){
    HANDLE hConsoleOutput;
    COORD dxCursorPosition;
    dxCursorPosition.X = x;
    dxCursorPosition.Y = y;

    hConsoleOutput = GetStdHandle(STD_OUTPUT_HANDLE);
    SetConsoleCursorPosition(hConsoleOutput, dxCursorPosition);
}

void clrscr(){
    system("cls");
}

当我尝试将程序放入表格菜单时遇到问题，如下所示:

输出将是这样的

Please Input your Complete Name: John Kenneth

Your Name is: John Kenneth

Answer 1

使用标准函数fgets。例如

fgets( name, sizeof( name ), stdin );
name[strcspn( name, "\n" )] = '\0';

请考虑到使用 goto 语句不是一个好主意。您应该忘记 C 中有 goto 语句。请使用 while 或 do-while 循环。
