Programming

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&lt;input

and it does not print 5 and 4, it prints some jumble of numbers.
Please help!

The reason that you are getting a bunch of numbers is that the int vars k and m are never assigned a value. You are displaying the values of what is in the memory address of k and in the memory address of m at the time of execution. The contents of an unassigned variable at execution time is commonly referred to as "compilter garbage".

Hi!

What exactly are you trying to do???
From what I've understood, you are trying to pass the values 5 and 4 from the file input to the file output. If this is what you are trying to do, your files should look like:

input:
======
5
4

output.c
=======
#include < stdio.h >

int main()
{
int k;
int m;

scanf("%d", &k);
scanf("%d", &m);

printf(" %d, %d\n", k, m);

return 0;
}

ofcourse, you can go about with your C Programs also by modifying your input.c file to "printf()" 'k' and 'm' and your output.c should be like the code pasted above, but you'll have to use pipes:
input | output

and just one more thing, check your uninitialized variables!!!
