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;
}
