如题,这是“无限猴子小说家”：
#includerand()%0x10000;
printf("%lc",t);
}
return 0;
}
那么“无限猴子音乐家”要怎么写呢？
要用C语言生成随机音频，可以使用C语言的音频库，比如PortAudio或SDL音频库。以下是一个使用PortAudio库生成随机音频的简单示例：
#include "portaudio.h"
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#define SAMPLE_RATE (44100)
#define FRAMES_PER_BUFFER (512)
#define NUM_SECONDS (5)
#define NUM_CHANNELS (2)
#define DITHER_FLAG (paDitherOff)
#define WRITE_TO_FILE (0)
typedef struct
{
float left_phase;
float right_phase;
}
paTestData;
static int paTestCallback( const void *inputBuffer, void *outputBuffer,
unsigned long framesPerBuffer,
const PaStreamCallbackTimeInfo* timeInfo,
PaStreamCallbackFlags statusFlags,
void *userData )
{
paTestData *data = (paTestData*)userData;
float *out = (float*)outputBuffer;
unsigned int i;
(void) timeInfo; /* Prevent unused variable warnings. */
(void) statusFlags;
(void) inputBuffer;
for( i=0; i<framesPerBuffer; i++ )
{
/* 生成随机音频数据 */
*out++ = (float)rand() / RAND_MAX;
*out++ = (float)rand() / RAND_MAX;
}
return paContinue;
}
int main(void);
int main(void)
{
PaStreamParameters outputParameters;
PaStream *stream;
PaError err;
paTestData data;
int i;
srand(time(NULL));
printf("Generating random audio...\n"); fflush(stdout);
err = Pa_Initialize();
if( err != paNoError ) goto error;
outputParameters.device = Pa_GetDefaultOutputDevice(); /* 默认音频输出设备 */
if (outputParameters.device == paNoDevice) {
fprintf(stderr,"Error: No default output device.\n");
goto error;
}
outputParameters.channelCount = NUM_CHANNELS;
outputParameters.sampleFormat = paFloat32;
outputParameters.suggestedLatency = Pa_GetDeviceInfo( outputParameters.device )->defaultLowOutputLatency;
outputParameters.hostApiSpecificStreamInfo = NULL;
err = Pa_OpenStream(
&stream,
NULL, /* no input */
&outputParameters,
SAMPLE_RATE,
FRAMES_PER_BUFFER,
paClipOff, /* 不需要剪裁处理 */
paTestCallback, /* 回调函数 */
&data ); /* 用户数据 */
if( err != paNoError ) goto error;
err = Pa_StartStream( stream );
if( err != paNoError ) goto error;
/* 等待音频播放完毕 */
Pa_Sleep(NUM_SECONDS * 1000);
err = Pa_StopStream( stream );
if( err != paNoError ) goto error;
err = Pa_CloseStream( stream );
if( err != paNoError ) goto error;
Pa_Terminate();
printf("Done generating audio.\n");
return 0;
error:
Pa_Terminate();
fprintf(stderr, "An error occurred while using the portaudio stream\n");
fprintf(stderr, "Error number: %d\n", err );
fprintf(stderr, "Error message: %s\n", Pa_GetErrorText( err ) );
return -1;
}

"无限猴子音乐家"的实现方式类似于"无限猴子小说家"，不同的是需要生成的是音乐而不是文字。以下是一个简单的示例程序，它会随机生成指定数量的MIDI音符：
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#define NOTE_COUNT 128
#define VELOCITY_COUNT 128
int main(void) {
srand((unsigned int)time(NULL));
int note_count, velocity_count;
printf("请输入要生成的音符数和速度数(0 < 音符数 <= %d, 0 < 速度数 <= %d):\n", NOTE_COUNT, VELOCITY_COUNT);
scanf("%d %d", ¬e_count, &velocity_count);
int i;
for (i = 0; i < note_count; i++) {
int note = rand() % NOTE_COUNT;
int velocity = rand() % velocity_count;
printf("音符:%d 速度:%d\n", note, velocity);
}
return 0;
}
这个程序使用了MIDI音符的编号和速度来表示音乐，其中音符编号的范围是0-127，速度的范围也是0-127。可以根据实际需要调整生成音符的范围和数量。同时，还可以使用第三方库来生成更复杂的音乐，例如MIDI库。
