C语言利用fgetc复制拷贝文件内容

#include <stdio.h>

#include <stdlib.h>

//文件的内容复制

int main(int a,char *argv[]){

	if(a!=3){

		printf("useage:%s source!\n", argv[0]);

		exit(1);

	}

	FILE *fp1, *fp2;

	fp1 = fopen(argv[1],"r");

	if(fp1==NULL){

	     printf("source file open error");

	     exit(1);

	}

	fp2 = fopen(argv[2],"w");

	if(fp2==NULL){

	     printf("target file open error");

		exit(1);

	}

	int ch;

	while((ch=fgetc(fp1)) != EOF){

		fputc(ch, fp2);

	}

	//关闭流

	if(fclose(fp1)!=0){

		printf("source file close error");

	}else if(fclose(fp2)!=0){

		printf("target file close error");

	}

	return 0;
