Converting PHP to C and I need a little help

Allenport · #1 14-Aug-2006, 09:35

Ok so I coded something in php (what I am good at) and it keeps timing out on my server so now I am trying to do it in "C" (I have not so much experience).

Basically all I did was take my PHP code and thak the function that does the calculations and try to turn that function into C code. (I know it's sloppy

)
What I need help with is fixing some of my errors and getting the code to print the results of the calculations to a text file.

CPP / C++ / C Code:

#include <stdio.h>
#include <string>
int temp_file_name, record_counter, total_requests, total_transfers, success_transfers, problem_array, fp, j, k; 
int problems_counter, line, fName, fTime, fTask, fStatus, user_array[1000], temp_name, temp_time, temp_task, t_status;

int main(int argc, char** argv){
    
}

   FILE *fp;   /* file pointer */

  /* see if correct number of command line arguments */
   if(argc !=2)
    {
      printf("File not found \n");
      exit(1);
    }

   /* open file for input */
   if ((fp = fopen(argv[1], "r"))==NULL)
    {
      printf("Cannot open file \n");
      exit(1);
    }
	

   record_counter = 0;
	while(!feof(fp))
	{
		line = fgets(fp,1024);
		line = rtrim(line);
	
		if(line == "" || strchr(line,"|") == FALSE)
		{
		
			break;
		}
		list(fName,fTime,fTask,fStatus) = split("\|",line);
		temp_file_name = strchr(fName,"/");
		temp_file_name = ltrim(temp_file_name,"/");
		temp_file_name = rtrim(temp_file_name,"/");
		if(temp_file_name == "")
			break;
		user_array[record_counter] = array(temp_file_name, fTime, fTask, fStatus);
		record_counter++;
	
	}

	total_transfers = 0;
	total_requests = 0;
	success_transfers = 0;
	problem_counter = 0;
	file_name_array_counter = 0;
	for(j = 0; j < record_counter; j++ )
	{
	
		temp_name = user_array[j][0];
		temp_time = user_array[j][1];
		temp_task = user_array[j][2];
		temp_status = user_array[j][3];
		problem_array[problem_counter] = array(temp_name,temp_time,temp_task,temp_status);
		problem_counter++;
	
		if(temp_status == "RM")
			total_requests++;
		else if(temp_status == "RE")
			total_transfers++;
		else if(temp_status == "RG")
		{
			success_transfers++;
		
			for(k = 0; k < problem_counter; )
			{
				if(temp_name == problem_array[k][0])
				{
					
					if(problem_array[k][2] == temp_task || (temp_task == "UF" && problem_array[k][2] == "DFR"))
					{
						t_status = problem_array[k][3];
						if(\problem_array[k][3] == "RF")
						{
							total_requests--;
						}
						if(problem_array[k][3] == "RE")
						{
							total_transfers--;
						}
						array_splice(problem_array,k,1);
						problem_counter--;
						if(t_status == "RG")
							break;
						if(empty(problem_array))
						{
							
							break;
						}
					
						if(problem_counter != 0 && problem_counter != k)
						{
							if(problem_array[k][0] == temp_name&& 
								problem_array[k][3] == "RG" &&
								problem_array[k][2] == temp_task)
							{
								array_splice(problem_array,k,1);
								problem_counter--;
								break; //stop searching in problem array
							}
						}
						else
							break; //problem_counter is 0 - so stop searching in problem array
					}
					else
					{
							k++;
					}
					if(empty(problem_array))
					{
						
						break;
					}
				}
				else
				{
						k++;
				}
			}
		}
	}
	
	if(!empty(problem_array))
	{
		
		process_problem_array();
	}
	if(!empty(problem_array))
	{
		
		total_requests += total_transfers;
	}
}

There are 36 errors in my code and I am stuck. Any and all help would be appreciated.

If you are converting to c, then why does your file end with .cpp?

Anyway, (just for a start, there will be other errors/warnings) it looks like you have nothing in main(), because there appears to be an extra '}' in the wrong place.

Yeah I fixed that and its cpp because I am using a C++ compiler.

If you are writing C, the extension needs to be C. A file ending in CPP will be built as C++, not C
