Hi,

Can anyone tell me general ways to access command-line arguments? plz give an example.

Thanks,

hey,

Command line arguments are space seperated character strings. In our contest, you enter these strings in a special window in the client.

These arguments are given to your program in specially defined character arrays. In C/C++ the number of arguments is also passed into your program in a specially declared integer. In java, this can be obtained by getting the length of the argument array, as shown below.

In the code skeletons (provided in the client), you can access the command line arguments in the following ways.:


Example of using command line args with C++

#include <stdio.h>
#include <stdlib.h>

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

for (i = 1; i < argc; i++)
printf("%s ",argv[i]);

printf("\n");

printf("The first argument as a number is: %d\n", atoi(argv[1]) );

return 0;
}

Java
