2) Write a C Program that separates Odd and Even numbers from Integers using files.

 Write a program code in C which creates a data file of integers and  enters at least twelve integers through standard input in the file. Add a program code which reads these numbers .The program then should write all odd numbers to a file called ODD and all even numbers to a file called  EVEN. 

source file name: oddeven.C

#include<stdio.h>

int  main()

{

int n;

FILE *f1, *f2, *f3;

f1=fopen("data.txt","r");

f2=fopen("odd.txt","w");

f3=fopen("even.txt","w");

while(fscanf(f1,"%d",&n)!=EOF)

{

if(n%2==0)

fprintf(f3," %d",n);

else

fprintf(f2," %d",n);

}

//getch();

return 0;

}

 

Output available in following files:

data.txt (12,45,-78,58,-456,36,79,96,-59,65,111,-178)

even.txt(12,-78,58,-456,36,96,-178)

odd.txt(45,79,-56,65,111)
