Command-line Parameters in C program?

Question

How do I read command-line parameters in C? For example, in

./test --help

or

./test --build

how do I access "--build" or "--help"?

Answer 1

Your parameters are in argv:

int main(int argc, char **argv)

if you printf the content of argv (argv[0],argv[1] etc) youll get the idea.

try:

int main (int argc, char **argv)
{
    for(int i = 0;i< argc;i++) 
        printf("%s
",argv[i]);
}
