将字符串写入文件

#include <stdio.h>
#include <stdlib.h>
int main()

    char sentence[1000];
    FILE *fptr;
    fptr=fopen("runoob.txt","w");
    if(fptr==NULL)
    
        printf("error");
        exit(1);

    
    printf("输入字符串:\\n");
    fgets(sentence, (sizeof sentence / sizeof sentence[0]), stdin);
    fprintf(fptr,"%s", sentence);
    fclose(fptr);
    return 0;

java如何将一个InputStream写入文件？

参考技术A

java通过InputStream读取和写入文件操作实例代码

1. File to InputStream

File file = new File("file.xml");
InputStream inputStream = new FileInputStream(file);

2.InputStream to File

InputStream inputStream = new FileInputStream("file.xml");

OutputStream  outputStream = new FileOutputStream("file-new.xml");

int bytesWritten = 0;
int byteCount = 0;

byte[] bytes = new byte[1024];

while ((byteCount = inputStream.read(bytes)) != -1)

outputStream.write(bytes, bytesWritten, byteCount);
bytesWritten += byteCount;

inputStream.close();
outputStream.close();
