我究竟做错了什么？ （C）

Question

我真的不知道我对此做错了什么。每次我编译它，在第四个用户输入时，它只是停止并显示返回的＆＃34;进程＆＃34;东西。

#include <stdio.h>
#include <conio.h>

int main() {

char firstname[15], class, swordch0c1, swordch0c2;
int health, healthtot, armor, armortot;

printf("Hello there! Could I have your first name?\n>");
scanf("%s", firstname);

printf("\n---------------------The Legend of %s---------------------", firstname);
printf("\nPress Enter to continue.");
getch();

printf("\n\n\nYou are %s, a(n): \nA.Swordsman\nB.Assassin\nC.Archer\nD.Mage\n>", firstname);
scanf(" %c", &class);

/*swordsman story starts here*/
if (class=='a' || class=='A')
    {
    printf("\n\nThere you stand, at your boring everyday post.\nWhen you joined the army, you thought it would be more exciting than this.\nJust then, you see your general walking towards you.");
    printf("\n\nYou quickly improve your posture. \"Soldier, I have an opportunity for you\"\nA.\"Really? What is it?\"\nB.\"I'm not interested\"\n>");
    scanf(" %c", &swordch0c1);

    if (swordch0c1=='b'||swordch0c1=='B')
        {
        printf("\n\"But... I didn't even tell you what it was. Okay, suit yourself\" You are DOOMED to a life of boredom.\n\n\n\n\n");
        }

    if (swordch0c1=='a'||swordch0c1=='A')
        {
        printf("\n\n\n\"Well, you see, there's this dragon. He's been causing big problems.\nHe's destroyed villages, harrassed the priests on the mountain,\n");

... 编辑：它允许我输入第四个输入。点击进入后，它显示进程返回的内容。

这条线几乎肯定是问题所在：

scanf(" %c", &swordch0c1);

您要求读取单个字符，但要实际输入字符，您必须输入两个字符： A 输入。此scanf来电将会读取'A'，下一个scanf来电将会读取'\n'（ Enter ）键，该键仍在输入缓冲区。

我建议将fgets()用于所有用户输入。处理这种方式要容易得多，因为它与用户实际输入输入的方式相匹配（文本行加上 Enter ）。
