C教程-----數(shù)據(jù)類型、變量和運(yùn)算符(1)

1. Turbo C程序的一般組成部分
    Turbo C 2.0 象其它語言一樣按其規(guī)定的格式和提供的語句由用戶編寫應(yīng)用程
    序。 請看下面一段Turbo C源程序。 例1:
    /*Example program of Turbo C*/
    #include /*包含文件說明*/
    void lgc(void);/*子函數(shù)說明*/
    char answer;/*定義全程變量*/
    int main()/*主函數(shù)定義*/
    {
    char a;/*定義局部變量*/
    clrscr();
    gotoxy(12,3);
    puts("Welcome to use Turbo C2.0!");
    gotoxy(15,13);
    printf("--Exit");
    gotoxy(15,15);
    printf("--Continue");
    while(1)
    {
    a=getch();
    if(a==27)
    break;
    if(a==13)
    {
    lgc();
    if(answer==’y’||answer==’Y’)
    {
    gotoxy(23,14);
    puts("Please Write to the Company");
    getch();
    break;
    }
    }
    }
    return(0);}void lgc(void){
    clrscr();
    gotoxy(12,8);
    printf("The Excellent Selection!");
    gotoxy(21,12);
    printf("Do you have any question?(Y/N)");
    answer=getche();}
