your request are so general. Please specify yr requirement to get a detail help.

I suppose that you are using C language. Here is your function

#include <stdlib.h>

int  RunSystemCmd(char *pfilename)
{
    char buff[512] = {0};
    if (pfilename == NULL) return -1;
    sprintf(buff,"HandBrakeCLI -i /dev/hdc -o /root/%s -b 1024 -B 128 -R 48 -E faac -f mp4 -w 368 -l 208 -m", pfilename);
    return system(buff);
}

I think you should change your code as following:

#include<iostream>
#include<stdio.h>
#include<stdlib.h>
#include<math.h>
#include<string.h>

using namespace std;
main()
{ 
  // char *filenames[] = {"file1","file2","file3",NULL};
  int n; 
  char buf[256];
  FILE *fp = NULL;
  cout<<" enter number of input files :";
  cin>>n;
  for(int i =0;i < n;i++){
    sprintf(buf,"file%d.dat",i+1);
    fp = fopen ( buf,"w");
    if (fp == NULL) break;
    fprintf(fp,"Copy \"C:\\Program Files\\prog\\prog%d.IN\" prog.In\n",i+1);
    fclose(fp);
   }
}
