How to install opengl on windows xp. So,you need a library to handle run time access of Openg API function and best library is GLEW. But if you are using Modern Opengl version (upto latest version 4.x) you can't call the opengl API function just include freeglut because in modern version Opengl API function are called at run time rather than compile time.

New download of DEV C will compile and run sources, then save the source (.cpp) and Application (.exe). DEV C will let me re-load the source, and it will run again. The Application appears to re-load, but it will not run. The ONLY msg I get is that DEV has turned the problem over to our NOD32ANTIVIRUS. I suspect pilot error, but even that. Feb 28, 2018 argc stands for argument count and argv stands for argument values. These are variables passed to main function when it starts executing. When we run a program we can give arguments to that program like −. I am using Dev C 5.11 for some time. I think I meet with a bug of it. When I start. 4 years ago Robbert Williams modified a comment on discussion Compiling. I have this activity for programming class. I'm only allowed to place codes where. 4 years ago Robbert Williams posted a comment on. That might be an issue with the used GCC or you did something wrong. This or that way this is surely not linked anyhow to dev-cpp. Voting to close.

In C++ it is possible to accept command line arguments. Command-linearguments are given after the name of a program in command-line operating systems like DOS or Linux, and are passed in to the programfrom the operating system. To use command line arguments in your program, youmust first understand the full declaration of the main function, whichpreviously has accepted no arguments. In fact, main can actually accept twoarguments: one argument is number of command line arguments, and the otherargument is a full list of all of the command line arguments.

The full declaration of main looks like this: The integer, argc is the ARGument Count (hence argc). It is the number of arguments passed into the program from the command line, including the name of the program.
The array of character pointers is the listing of all the arguments. argv[0] is the name of the program, or an empty string if the name is not available. After that, every element number less than argc is a command line argument. You can use each argv element just like a string, or use argv as a two dimensional array. argv[argc] is a null pointer.
How could this be used? Almost any program that wants its parameters to be set when it is executed would use this. One common use is to write a function that takes the name of a file and outputs the entire text of it onto the screen. This program is fairly simple. It incorporates the full version of main. Then it first checks to ensure the user added the second argument, theoretically a file name. The program then checks to see if the file is valid by trying to open it. This is a standard operation that is effective and easy. If the file is valid, it gets opened in the process. The code is self-explanatory, but is littered with comments, you should have no trouble understanding its operation this far into the tutorial. :-)
