How to set parameters in command line

[vutek0328]

I have a code of which I need to set parameters in order to run.

I'm wondering how I can input the parameters through the command line.

./brownian 10 15 100 200

with each number being a parameter for a certain variable in the code.

I found this on the internet, but i'm not sure how that can help me.

#include <stdio.h>

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

printf("%d\n",argc);
for (x=1; x<argc; x++)
printf(argv[x]);
return 0;
}

You could try just compiling it and running it to see what it does.

For the command line

./brownian 10 15 100 200

in

int main(int argc, char *argv[])
{
...
}

then

argc = 5

argp[0] = "./brownian"
argp[1] = "10"
argp[2] = "15"
argp[3] = "100"
argp[0] = "200"

allowing you to access the data from the command line
