Compile C language programs in Linux 1. First install the gcc package, run the C ++ program, and install the gcc-c ++ package If no installation is available, install it on your own. 2. Edit the C language program, Print the multiplication table [Root @ Db1 c] # vim chengfa. c On the editing page, enter # Include Save and exit 3. Compile with the gcc command After compilation, an a. out file

Someone in the group yesterday asked Linux C how to obtain the absolute path of the program. When I first read this question, I thought it was very simple. Just use getcwd or argv [0. I wrote a program and tried it, # Include Compile: Gcc-wall-pipe-g-static-O getpath. c It is found that getcwd does not work. This function returns the current execution path. If you execute this program in another directory, such ~ /. The call will not work. Argv

Run the shell command through the C program, using the EXECLP function EXECLP Several parameters are: file name, each parameter, (char*) 0 Where the first parameter in the "Parameters" section is the file name (equivalent to the file name entered two times) Last parameter Write (char*) 0 Yes File B.cpp Code: Loop through the commands → execute the command until you press CTRL + C to end #include Compile b.cpp into executable file B (input command: g++ b.cpp-o b) Then open file B and enter the c

The simplest way to count the size (number of bits) of a directory is to enter the command in the console: DU-SB Directory Address implementing this function in C + + is achieved by recursively traversing files and subdirectories in the directory. It is important to note that because the byte count is too large, only one integer is counted for the number of bytes, and a larger directory will overflow. So I used TB, GB, MB, KB, and byte five levels to represent the size of a directory. My code

The most important software development tool in Linux is GCC. GCC is the GNU C and C + + compiler. In fact, GCC can compile three kinds of C, C + +, and object C (an object-oriented extension of the C language). Use the GCC command to compile and connect both C and C + + source programs at the same time. #DEMO #: HELLO.C If you have two or a few C sources, you can also easily compile, connect, and build e

Open terminal (terminal) and enter the following command:Export swt_gtk3=02. Then enter the Eclipse directory, open the Eclipse,ini file with gedit, and modify it as follows:Cd/home/lt/eclipse/jee-mars/eclipse/sudo gedit Eclipse.ini3. In front of

Solutions for QT programs not being able to input Chinese in LinuxA netizen asked me how to enter Chinese in the QT application of Linux, I didn't think it was a problem at first, but I tried it on the back. Not only QT-made applications, even QT creator are not supported. After reading some information, understand the QT application methods, here to share with you.Write a bash script that reads as follows:

Here's a piece of code:#include Execution results under Linux:Main call FUN1 Call fun---exit exitFor the problem with this result:Obviously did not call the fun function, why do the fun function, the function is how to jump?How does the stack frame save the information and return it?Analysis Reason:View important stack segments in assembly code650) this.width=650; "src=" Http://s1.51cto.com/wyfs02/M02/83/17/wKiom1dqdS7ChdVmAACpe1R_wTY604.png "title=" screen Shot 2016-06-22 at 19.22.39.png "alt="

waste of hard disk space; (two executable files contain ONE.O)Second, when the program loads, the memory is wasted. (Since the ONE.O was loaded two times)Dynamic library, you can solve the above two problems.The same code, the hard disk should be able to exist only one copy, in memory should only exist in order to achieve the savings.This is why, dynamic linking is the time when the program is loaded, only to link. (Because the early link, do not occupy the hard disk space?)That's why, dynamic

file, and also to a target file, that is, there is only one function in a target file, there is no other thing.When you use it, you can pick and choose which target file to link to.For example, your colleague already has these:ONE.C contains the void One () {} functionTWO.C contains the Void () {} functionTHREE.C contains the void three () {} functionWait a minute....... And it also provides a header file called All.h, which contains a declaration of all the functions he wrote.When you use it,
