i was writting a program that can read a set of numbers file called dog.txt;
and also writes to two file separating odd and even. i was able to compile my program however, the output expected is not the same which was supposed to be even numbers in one file called EVEN, odd numbers in file odd.
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char *argv[])
{
int i;
int even,odd;
int num;
if (argc != 4) {
printf("Usage: executable in_file output_file\n");
exit(0);
}
FILE *dog = fopen(argv[1], "r");
FILE *feven= fopen(argv[2], "w");
FILE *fodd= fopen (argv[3], "w");
while (fscanf(dog, "%d", &num) != EOF)
{
if (0==i%2){
i++;
printf("even= %d\n", num);
}
else if(i!=0){
i++;
printf("odd= %d\n", num);
}
}
fclose(feven);
fclose(fodd);
fclose(dog);
return 0;
}
output:
even= 1
odd= 2
even= 34
odd= 44
even= 66
odd= 78
even= 94
odd= 21
even= 23
odd= 54
even= 44
odd= 65
even= 78
odd= 68
even= 92
