Command Line Arguments‣ Recommended usage:– Upon startup check argc to make surethe user has input the desired numberof args (remember the executablecounts as one of the args.)‣ Problem:– Each argument is a textstring…for numbers we want itsnumeric representation not itsASCII representation– cstdlib defines:atoi() [ASCII to Integer] andatof() [ASCII to float/double]– Each of these functions expects apointer to the string to convertargv[0]argv[1]argv[2]argv[3]#include #include using namespace std;p r o g 1 \04 \00 . 5 \01 0 0 0 0 0 \0// char **argv is the same as char *argv[]int main(int argc, char **argv){int init, num_sims;double p;if(argc < 4){cout
Exercise‣ Write a program that– Defines a function that accepts an integer, N as input and thengenerates an array of N random integers and returns it to the caller– From main ask the user for N, call your function and "store" thereturn result– Iterate over the array returned by your function and average thevalues.– Print that average…is that value close to _______________(expected value)?© Copyright 2013 Brent Nash & Mark Redekopp, All Rights Reserved11
