在命令行参数数组中查找元素数量？

Question

I'm working off of a Linux command line with g++ and the code will be executed like so:

./mycode arg1 arg2 arg3 ... 

This works fine as I am using the array argv[] and the following for main:

int main (int argc, char *argv[])

However there is a part of my program where I need to know the number of command line arguments given. sizeof() is failing me here. Any ideas of how this could be accomplished?

Answer 1

这就是argc参数是为-它是的ARG umentÇ'mount argv （ARG ument 价值）阵列。
