文件的简单操作

int main(int argc, const char * argv[]) {
    FILE *fp;
    char ch,fileName[10];
    scanf("%s",fileName);
    if ((fp=fopen(fileName, "w"))==NULL) {
        printf("无法打开文件");
        exit(0);
    }
    ch=getchar();
    ch=getchar();
    while (ch!='#') {
        fputc(ch, fp);
        putchar(10);
    }
    return 0;
}
