using argv in c++ code example
Example 1: c++ argv
#include <iostream>
using namespace std;
int main(int argc, char** argv){
for(int i = 0; i < argc; i++){
cout << "argv" << i << ": " << argv[i] << endl;
}
return 0;
}
Example 2: command line options in c++
int main(int argc, char *argv[])
{
for(int i = 1; i < argc; i++){
if(!strcmp(argv[i], "-h") || !strcmp(argv[i], "--help") ){
printf("Usage: App <options>\nOptions are:\n");
printf("Option list goes here");
exit(0);
}else if(!strcmp(argv[i], "-c") || !strcmp(argv[i], "--custom")){
printf("argument accepted");
}else{
if(i == argc-1){
break;
}
MessageBox(NULL, TEXT("ERROR: Invalid Command Line Option Found: \"%s\".\n", argv[i]), TEXT("Error"), MB_ICONERROR | MB_OK);
}
}
MessageBox(NULL, TEXT("ERROR: No Command Line Option Found. Type in --hep or -h"), TEXT("Error"), MB_ICONERROR | MB_OK);
}
