Dev C++ 5.11 Inputting Argv Argc
Jan 11, 2018 Learn how to take contents of an input #file so that program can #read and process it. How to display contents on to console window and also. Learn how to accept command line arguments in C using the argv and argc parameters to main. Size of dev c. Starting out How to begin. Command line arguments in C using argc and argv. Command-line arguments are given after the name of a program in command-line operating systems like DOS or Linux, and are passed in to the program from the operating.
Hi everyone,
i have this problem. im using in my program input variables argc and argv. when im firstime start program with some input parameters which fill out argv everything is ok (BTW : argc and argv are input parametres for my subprogram which im calling in my main function) but when im calling that subprogram again in that main with another argv parametres it works bad. i think that problem is that when im going back from that subprogram by return it will not erase variables in that subprogram and when im calling it secondly than with another parametres he dont know what to do So my question is: Is there some possible way how to erase all those variables before that second calling?? or some another way how to solve this problem??
In that code below you can see that when i start program i put parametres similar like for char *mP only IP address is on second place so mujAVG1 i get without any problems but then when i put for Xping another arguments in that form what you can see ( there has to be IP on the last place couse at the end of first calling Xping parameters in argv are in this sequence) and program will retype that argv but in result of ping isnt 5 echo massages like it should be but only one it dont have lengh 20 data bytes but same like in first start 32 and if i took a look what is inside argv after all of this there is still that first sequence of parametres what i put on the beginig of program.

You can also pass parameters to your program through Dev by going to Execute - Parameters. Type the name of your file in the text field and then run your program. Edited by cod3b3ast, 23 December 2009. Aug 07, 2009 argc tells you how many command-line arguments there were. It is always at least 1, because the first string in argv (argv0) is the command used to invoke the program.argv contains the actual command-line arguments as an array of strings, the first of which (as we have already discovered) is the program's name.

I think that. May 27, 2011 In this tutorial on C I want to show you the command line arguments. Actually we will give parameters to the main function. Jan 10, 2015 In this tutorial I explain the meaning of the argc and argv variables that are often passed in the main function of a C or C program. This tutorial I explain the meaning of the argc and argv.
