hi,
the below attached program uses the argument command line the copy a file to
another file. my question is what can I change in the program to make only
part of the first file be copied to the second.
#include<stdio.h>
int main(int argc, char *argv[])
{
FILE *inFilePtr; /*input file pointer*/
FILE *outFilePtr; /*output fole pointer*/
int c,i;
/*check number of command-line arguments */
if(argc != 3){
printf("Usage: mycopy infile outfile\n");} /*end if*/
else /*if input file can be opened*/
{
if((inFilePtr=fopen(argv[1],"r"))!=NULL) /*if input file can be
opened*/
{ if((outFilePtr =fopen(argv[2], "w")) != NULL) /*if output file can
be opened*/
{while((c = fgetc(inFilePtr)) !=EOF) /*read and output characters*/
{
fputc(c,outFilePtr);}/*end while*/
}/*end if*/
else /*output file could not be opened*/
{printf("File\"%s\" could not be opened\n", argv[2]);
} /*end else*/
}/*end if*/
else /*input file could not be opened*/
{ printf("File\"%s\" coulk not be opened\n", argv[1]);} /*end else*/
} /*end else*/
return 0; /*indicates successful termination*/
}/*end main*/
