If the program name is hello then:
int main(int argc,char *argv){
----------------
----------------
----------------
statements;
return o;
}
The output id:
cd>exc hello.c jailani sukanya tej
the value of argc is :3
and argv[0] is hello
argv[1] is jailani
and so on.

Command line argument is the information followed by program's name on the command line of operating system.
Two special built in functions are present which specify the number of arguments on command line and pointer to an array of character pointers, those are argc and argv respectively.
Hence 1st argument is always program name.
