Passing External Enviroment Variable Problem

hednast · Aug 3, 2005

Hai....I am having problem in passing a value into an exe.

Eg:
c:\test.exe %computername%

the test.exe is a turbo c program.

I tried writing a small program that looks like below:

main(char *val)
{
printf("Value is %c ",val);
}

But I cannot get the value as I want. Please help.....

Try this:

Code:

void main(int argc, char* argv[])
{
    int count;

    for(count=1; count <= argc; count++)
        printf("Value is %c \n",argv[count]);
}

hope this helps and best regards

Hey C-Man, you must be half-asleep!

void main() is an error.
%c is an error.
count <= argc is an error.
missing stdio include.

Try this:

Code:

#include <stdio.h>

int main(int argc, char *argv[])
{
  int count;

  for (count=1; count < argc; count++)
    printf("Value is %s\n", argv[count]);
  return 0;
}

Or the compact version:

Code:

#include <stdio.h>

int main(int argc, char* argv[])
{
  while (*++argv)
    printf("Value is %s\n", *argv);
  return 0;
}
