c/c++语言开发共享我的function或主要问题是什么？

除了我的“播放”function之外，我的所有代码都按照我希望的方式工作。 我正在尝试让程序读取“记录”function创建的.txt文件，然后回放说明。 不幸的是，当用户按下P以播放他们记录的音符时，它只是不断弹出相同的菜单而不是前进到程序的下一步。 任何帮助高度赞赏，它可能是一些小的，但我一直在努力，我正在努力解决自己的问题。

#include "aservelibs/aservelib.h" #include  #include  #include  float mtof(int note, float frequency); FILE play(void); FILE record(void); FILE record2(void); int main() { FILE *textFilePointer; FILE *textFilePointer2; int counter = 0; char user; do { printf("Press A to Record 1st Melody (A), B to Record 2nd Melody (B)nP to Play Melodies (P):"); scanf(" %c", &user); if (user == 'a' || user == 'A') { textFilePointer = fopen("/Users/Luke/Desktop/midinotes1.txt", "w"); *textFilePointer = record(); counter = 0; } else if (user == 'b' || user == 'B') { textFilePointer2 = fopen("/Users/Luke/Desktop/midinotes2.txt", "w"); *textFilePointer2 = record2(); counter = 0; } else if (user == 'p' || user == 'P') { textFilePointer = fopen("/Users/Luke/Desktop/midinotes1.txt", "r"); textFilePointer2 = fopen("/Users/Luke/Desktop/midinotes2.txt", "r"); counter = 0; } } while(counter  0) { fprintf(file, "%d, %dn", note, velocity); counter++; } } while (counter  0) { fprintf(file, "%d, %dn", note, velocity); counter++; } } while (counter < 16); fclose(file); return *file; } 

  fclose(file); return *file; 

 else if (user == 'p' || user == 'P') { ... play (); } 

  file = fopen("/Users/Luke/Desktop/midinotes1.txt", "r"); file = fopen("/Users/Luke/Desktop/midinotes1.txt", "r"); 

 file = fopen("/Users/Luke/Desktop/midinotes1.txt", "r"); if(file) //if fopen fails, file == NULL { do { ... 

 void recordToFile(char const* file) { int counter; FILE* file = fopen(file, "w"); if ( file == NULL ) { // Deal with error } else { // Your code to record to the file. // Close the file fclose(file); } } void record(void) { recordToFile("/Users/Luke/Desktop/midinotes1.txt"); } void record2(void) { recordToFile("/Users/Luke/Desktop/midinotes2.txt"); }
