: Write a C program to take a list of N numbers, separate even and odd numbers and put them in two appropriate files (evenfile and oddfile). Use File Handling concept.

Ans.

#include<stdio.h>

#include<math.h>

void main()

{

FILE *all,*even,*odd;

int number,i,records;

scanf("INPUT THE TOTAL NUMBER OF RECORDS THAT U WANT TO ENTER

");

scanf("%d",& records);

all=fopen("ANYNUMBER","w");

for(i=1;i<=records;i++)

{

scanf("%d",&number);

if(number==-1)break;

putw(number,all);

}

fclose(all);

all=fopen("ANYNUMBER","r");

even=fopen("EVENNUMBER","w");

odd=fopen("ODDNUMBER","w");

while((number=getw(all))!=EOF)

{

if(number%2==0)

putw(number,even);

else

putw(number,odd);

}

fclose(all);

fclose(even);

fclose(odd);

even=fopen("EVENNUMBER","r");

odd=fopen("ODDNUMBER","r");

scanf("THE EVEN NUMBERS ARE");

while((number=getw(even))!=EOF)

scanf(" %4d",number);

scanf("THE ODD NUMBERS ARE");

while((number=getw(odd))!=EOF)

scanf("  %4d",number);

fclose(even);

fclose(odd);

}
