Program to read numbers from two files using fscanf function and write it in another file using fprintf function in ascending order

 
# include<stdio.h>
# include<conio.h>
void main(int argc, char *argv[])
{
    FILE *ptf1,*ptf2,*ptf3;
    int a,b;
    clrscr();
    a=b=0;

    ptf1=fopen(argv[1],\"r\");
    ptf2=fopen(argv[2],\"r\");
    ptf3=fopen(argv[3],\"w\");

    fscanf(ptf1,\"%d\",&a);
    fscanf(ptf2,\"%d\",&b);

    while(1)
    {
        if(b==0 || a==0)
            break;
        if(a<b)
        {
            fprintf(ptf3,\"%d \",a);
            fscanf(ptf1,\"%2d\",&a);
        }
        if(a>b)
        {
            fprintf(ptf3,\"%d \",b);
            fscanf(ptf2,\"%2d\",&b);
        }
        if(a==b)
        {
            fprintf(ptf3,\"%d \",a);
            fscanf(ptf1,\"%2d\",&a);
            fscanf(ptf2,\"%2d\",&b);
        }
    }
    if(a==0 & b!=0)
    {
        while(1)
        {
            fprintf(ptf3,\"%d \",b);
            //putw(b,ptf3);
            //b=getw(ptf2);
            fscanf(ptf2,\"%2d\",&b);
            if(b==0)
                break;
        }
    }
    if(a!=0 & b==0)
    {
        while(1)
        {
            fprintf(ptf3,\"%d \",a);
            fscanf(ptf1,\"%2d\",&a);
            if(a==0)
                break;
        }
    }
    fclose(ptf1);
    fclose(ptf2);
    fclose(ptf3);
}
