文件复制 c语言实现

文件复制，在linux中，将生成的read.o 重新文件拷贝一份复制到ReadCopy.o中，并且更改ReadCopy.o文件的操作权限。使其能够正常运行。

#include <stdio.h>
int main(){
FILE *r_file = fopen ("read.o","rb");
FILE *w_file = fopen ("ReadCopy.o","w");
char temp[10];
int judge = 0;
if (r_file){
do {
judge = fread(temp,sizeof(char),10,r_file);
if (!judge){
break;
}
fwrite(temp,sizeof(char),10,w_file);
}while(1);
}
fclose(r_file);
fclose(w_file);
r_file = NULL;
w_file = NULL;
return 0;
}
