#include
int main(int argc, char *argv[])
{
~FILE *fp1, *fp2;
~char ch;
fp1 = fopen("file1.txt", "r");
~if (fp1 == NULL ) {
~~printf("file1.txt open error\r\n");
~~return -1;
~}
fp2 = fopen("file2.txt", "w")
~if (fp2==NULL ) {
~~printf("file2.txt open error\r\n");
~~fclose(fp1);
~~return -1;
~}
~for (ch = fgetc(fp1); ch != EOF; ch = fgetc(fp1)) {
~~fputc(ch, fp2);
~}
~fclose(fp1);
~fclose(fp2);
~return 0;
