Thread: From input to output file creation

Hi,

I need to write down a program which contains an input file, the program needs to write an output file which contains the content from the input file in a specific order.

The input file contains:

name;surname;year
name;surname;year
name;surname;year
...

The resulting output file needs to have:

the initials1;theinitials1DTU;year;fullname
the initials2;theinitials2DTU;year;fullname
the initials3;theinitials3DTU;year;fullname
...

I hope some of you can give me some ideas how to write a program like this.

Best Regards
Urban

Tell you what... give it your best shot, post your code and we'll see...

Basically you have three steps to think about... loading the file, massaging the data and saving the new file...

Code:

void main ()
{
	
	
	char c;
	FILE * prt, *prt1;
	prt = fopen("Inputfil.txt","r");
	prt1 = fopen ("Outputfil.txt", "w");
	while((fscanf(prt, "%c", &c))==1)						
	{
		printf("%c",c);
		fflush(stdout);
		
		while (c!=';')										
		{
			fscanf(prt, "%c", &c);
		}
		fscanf(prt, "%c", &c);
		printf("%c", c);
		fflush(stdout);														
		

	
	
	}
	
	return 1;
	

	
	
}

I got stuck at at this point. So far this give me the the first two initials of the first line, and thats it. So the next step would be how to add 1 to the output line and so on.

i am an intermediate c programmer and i am still not very confident with all my programs. in your program you need to write to another file i suppose. then somewhere there should have been a fprintf if i am not wrong. Particularly inside your while loop. something like this:

Code:

while(fscanf(ptr,"%c",&c)==1)/*loop shall continue untill there are characters to read*/
{
         fprintf(ptr1,"%c",c);/*not the required code just an example*/
}

you will probably require to extract the necessary data and then print them into a file with some formatiing. also i didnot understand what is meant by DTU???

Ummm... not to nit pick too deeply... but Main or WinMain can return any value you assign to them.. it doesnt' have to be 0. I commonly return an error value or result code to be used in batch processing with "if errorlevel" statements.
