linux 编译运行c文件

在ubuntu安装gcc

编辑 test.c

/* Not stdio.h */
#include <unistd.h>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！
