Help with redirection
Here is my problem. I don't know make this redirection thing work. The output file (called output.c) looks like this
#include<stdio.h>
int main()
{
int k;
int m;
print f("%d\n", k);
printf("%d\n", m);
return 0;
}
the input file(called input.c) is this
#include<stdio.h>
int main()
{
int k;
int m;
k=5;
m=4;
return 0;
}
I then compile the output file and do
a.out<input
and it does not print 5 and 4, it prints some jumble of numbers.
Please help!
