c - 错误: Expected Expression '/' before token

Question

这是我的 C 程序。我在无法调试的代码中遇到错误。帮我找到解决方案。我收到此错误:在主函数的第一行中期待表达式“/”标记

Answer 1

1. 我认为，scanf("%c",&more);应该是scanf("%c",&type);
2. 您失踪了;在puts(album[i]?"Album":"Single")
3. 您失踪了#include <ctype.h>对于 toupper()功能

经过这些更改后，我能够在 Visual studio 2005 中正确编译并运行该程序(看起来)。
