Your declaration of main is correct. The numeric value will be passed into main in a stringized format as one of the values of argv. Assuming you pass it in as your first command line parameter it'll be in argv[1]. You can then use atoi() to convert it to an integer value.<br />
<br />
Something like...<br />
int n = atoi(argv[1]);<br />
<br />

int new;
if( argc > 1 ){
  new= atoi(argv[1]);
}

i doubt if you can change the signature of main method as:<br />
int main(int argc, int* argv[])<br />
<br />
what you can do is to convert char* into integers. this you can do using atoi method.<br />
<br />
check out:<br />

What I want to do is take an integer as input. &nbsp;How do I declare main?<br />
Would I say:<br />
int main(int argc, int* argv[])???<br />
<br />
If so, how then do I copy the argument I passed into a new variable?<br />
<br />
Thanks.

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.
