command-line-arguments

问题 Is there any simple way to manage command line arguments for C++ project (I suppose the same for C#) in Visual Studio like it works in Visual Studio Code where you have dropdown with different run presets? I'm developing CLI and need to change arguments pretty often. Now I have to copy paste them from txt file. I guess it's not the easiest way to handle this :) UPD: Just to clarify I'm speaking about Console application project properties -> Debugging -> Command Arguments block. 回答1: You can

问题 I am working on a program that is supposed to take one required command line argument and one optional command line argument. The first argument is the name of an output file where data will be written to, and the second is a number that will be used to calculate the data to be written to the output file. If the user does not enter a number, then it should just use a default value to calculate the data. For example, if the user entered command line arguments "Foo.csv 1024" the program would

问题 Can you pass your code directly into gcc? If so what is the command line option for it? For example: g++ -? 'int main(){return 0;}' I need to know because I am using a system command and I rather not make files: system("g++ -C "+code_string+" -o run.out"); Basile Starynkevitch solution worked, however I am getting compile errors when I use newlines: echo '#include\nint main(){printf("Hello World"); return 0;}' | g++ -x c++ -Wall -o myprog /dev/stdin Edit: fixed it echo -e '#include\nint main(

问题 I am trying to parse a command line using argparse from argparse import ArgumentParser argparser = ArgumentParser(prog="parse", description="desc") create.add_argument("--name",dest="name",required=True,help="Name for element") args = argparser.parse_args() print(args) When I execute this with below command python argparser.py --name "input$output$" The output is: ('args:', Namespace(name='input$')) Expected Output: ('args:', Namespace(name='input$output$')) Can you please help figure out

问题 I am trying execute my Python script as: python series.py supernatural 4 6 Supernatural : TV Series name 4 : season number 6 : episode number Now in my script I am using the above three arguments to fetch the title of the episode: import tvrage.api import sys a = sys.argv[1] b = sys.argv[2] c = sys.argv[3] temp = tvrage.api.Show(a) name = temp.season(b).episode(c) # Line:19 print ( name.title) But I am getting this error: File "series.py", line 19, in <module>: name = super.season(b).episode

问题 I have a simple program that prints out argv character by character, and I want to pass in carriage return ( '\r' or ASCII# 0x0D) as a program argument. How do I achieve this in linux OS (Ubuntu)? I am using bash. #include <stdio.h> #include <string.h> int main(int argc, char* argv[]) { int i; for(i = 1; i < argc; i++) { char* curr = argv[i]; while(*curr != '\0') { printf("[%c %x] ", *curr, *curr); curr++; } printf("\n"); } return 0; } Assuming our executable program is called test , if the

问题 I have a question regarding structuring of code. I have let us say three types of packages A,B and C. Now, classes in package A contains classes which contain the main() function. These classes need some command line arguments to run. In package B, there are classes which contains some public variables, which need to be configured, at different times. For example before calling function A, the variable should be set or reset, the output differs according to this variable. In package C, uses
