How to create a .txt file comparing the two rows from a file ?

[subhash1990]

I have a .txt file which contains 121 COLUMNS and 2 ROWS,now I want to create one new file new.txt which will contain only the class no(A,B,C) which is larger than the value 6 in ROW 2.How to create it?I have tried the following code.

my c.txt file look like following :

A B C D E ..... AAA
12 20 4 7 5 ..... 11

#include<stdio.h>
#include "conio.h"
#include "stdlib.h"
#include "string.h"


int main()
{
	FILE *fp,*fq,*dd;
	
	char Garbage[500];
	int a1[500];
	int i=0;

	fp=fopen("c.txt","r");
	fq=fopen("c.xt","r");
	dd=fopen("out.txt","w+");

	if(fp==NULL)
	{
	printf("\nNot Exists\n");
	exit(1);
	}


	for(i=0;i<=121;i++)
	{
	fscanf(fp,"%c",Garbage[i]);
	}

    for(i=0;i<=121;i++)
	{
	fscanf(fq,"%d",a1[i]);
	}
  
	if(a1>20)
	
	{
        fprintf(dd,"%c\n",Garbage);
		    
	}
		
	
	fclose(fp);
	fclose(fq);
	fclose(dd);
	return 0;
}
