linux下g++和gcc

gcc和g ++之间的区别 (Difference between gcc and g++)

Both are the compilers in Linux to compile and run C and C++ programs. Initially gcc was the GNU C Compiler but now a day's GCC (GNU Compiler Collections) provides many compilers, two are: gcc and g++.

两者都是Linux中用于编译和运行C和C ++程序的编译器 。 最初， gcc是GNU C编译器，但如今，今天的GCC(GNU编译器集合)提供了许多编译器，其中两个是： gcc和g ++ 。

gcc is used to compile C program while g++ is used to compile C++ program. Since, a C program can also be compile complied through g++, because it is the extended or we can say advance compiler for C programming language.

gcc用于编译C程序，而g ++用于编译C ++程序。 因为，C程序也可以通过g ++编译，因为它是扩展的，或者可以说是C编程语言的高级编译器。

编译器命令通过gcc编译C程序 (Compiler command to compile C program through gcc)

gcc  program.c  -o binary

program.c is the C source file name and binary is the name of binary (object file) that will be executed.

program.c是C源文件的名称，binary是将要执行的二进制文件(目标文件)的名称。

通过g ++编译C ++程序的编译器命令 (Compiler command to compile C++ program through g++)

g++  program.cpp  -o binary

program.cpp is the C++ source file name and binary is the name of binary (object file) that will be executed.

program.cpp是C ++源文件的名称，binary是将要执行的二进制文件(目标文件)的名称。

C示例(main.c)-编译，通过gcc运行 (C Example (main.c) - Compile, Run through gcc)

/* main.c */ #include 
    
      int main(){
       printf("Hello, World!\n");     return 0;}
    

Output

输出量

sh-4.3$ gcc main.c -o main    sh-4.3$ ./main    Hello, World!

C ++示例(main.cpp)-编译，通过g ++运行 (C++ Example (main.cpp) - Compile, Run through g++)

/* main.cpp */ #include 
    
      using namespace std; int main(){
      cout << "Hello World" << endl;        return 0;}
    

Output

输出量

sh-4.3$ g++ main.cpp -o main    sh-4.3$ ./main    Hello, World!
