我需要我的程序创建两个不同的文本文件(midinotes1 和 midinotes2)并在其中存储两位数据以供稍后读取。有没有不复制代码的有效方法?我知道我需要让 filepointer1 写入 midinotes1 和 filepointer2 写入 midinotes2 但我不知道如何让我的程序做到这一点? 感谢您的任何建议!
#include "aservelibs/aservelib.h"
#include <stdio.h>
#include <math.h>
#include <string.h>
float mtof(int note, float frequency);
int main()
{
FILE *textFilePointer;
FILE *textFilePointer2;
int note;
int velocity;
int program;
int counter = 0;
char user;
float frequency;
do
{
printf("Press R to Record (R) or (X) to Exit: \n");
scanf(" %c", &user);
if (user == 'r' || user == 'R')
{
textFilePointer = fopen("/Users/Luke/Desktop/midinotes1.txt", "w");
counter = 0;
if (textFilePointer == NULL)
{
printf("Error Opening file.\n");
}
else
{
do
{
note = aserveGetNote();
velocity = aserveGetVelocity();
if (velocity > 0)
{
fprintf(textFilePointer, "%d\n, %d\n", note, velocity);
counter++;
}
program = aserveGetProgram();
} while (counter < 16);
fclose(textFilePointer);
}
}
else if(user == 'x' || user == 'X')
break;
} while(user != 'x' || user != 'X');
return 0;
}
float mtof(int note, float frequency)
{
frequency = 440.0 * pow(2, (note-69) / 12.0);
printf("%d\n", note);
return frequency;
}
最佳答案
int index = 0;
char filename[128];
do
{
printf("Press R to Record (R) or (X) to Exit: \n");
scanf(" %c", &user);
if (user == 'r' || user == 'R')
{
snprintf(filename, 120, "notes%d.txt", (index+1));
textFilePointer = fopen(filename, "w");
counter = 0;
if (textFilePointer == NULL)
{
printf("Error Opening file.\n");
}
else
{
do
{
// your work
} while (counter < 16);
fclose(textFilePointer);
index++;
}
}
else if(user == 'x' || user == 'X')
break;
} while(user != 'x' || user != 'X');
return 0;
