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;
}
