for a program
int main(int argc char **argv) ....
&&
sizeof(int) number of arguments are possible
hence 32767 args are possible for a 32 bit computer

NEVER!If you are deciding the numbers of arguments on the basis of size of int in 32 bit compiler it should be 2^31-1. that is almost square of 32767.And The memory allocated to argv is from RAM. SO do you really think compiler allocates memory holding 2^31-1 strings of any size!
