How should character arrays be used as strings?（4个答案）
3天前关闭。
伙计们，我正在用c语言做一个票务程序，但是有一个小问题。我在结构体和正确打印结构体方面有问题。问题是：程序打印块在时间选项每次。as you can see time:20.00a or something我怎么能解决这个问题？有一个代码：

#define _CRT_SECURE_NO_WARNINGS
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <conio.h>
#include <windows.h>
#include <time.h>
void blink();
void bloksira(int a);
void pay();
struct ticketdetails
{
    char match[50];
    char tribunename[5];
    char time[5];
    char blok[1];
    int seatnumber[20];
    int ticketfee;
}ticket1;
int main()
{
    char choose[100],tribune[10],yesno[2];
    int  matchnumber;
    system("color B");
    blink();
    _getch();
    menu:printf("**********\nTICKET APP\n**********\n");
    printf("Choose your option:\n");
    printf("1-)Match\n2-)Concert\n3-)Events\n");
    scanf("%s",choose);
    if (strcmp(choose, "Match")==0 || strcmp(choose, "match")==0 || strcmp(choose, "MATCH")==0 || strcmp(choose, "1") == 0)

我以为没有时间块名称。例如时间：20.00时间：18.00
