在ubuntu安装gcc

编辑 test.c

/* Not stdio.h */#include 
    
      void main(){    char str[100];     /*Write on screen*/    write(1,"\nType Something : ",17);     /*Read at most 100 chars from console into 'str' */    read(0,str,100);     write(1,"\nYou typed :\n",13);     /*write 10 chars from 'str' to screen */    write(1,str,10);     /*newline*/    write(1,"\n",1);}
    

# gcc -o test test.c

完成后会出现一个可执行文件test，这就是编译好的文件，直接./test 就可以执行了！
