C language: define an integer variable and assign a value, and then output its value to the screen in three different ways (hint: directly refer to the variable name, level 1)
# include & ltstdio.h & gt
int？ main(){
int？ a= 10，* p 1 = & amp； a，* * p2 = & ampp 1；
printf("%d？ %d？ %d\n "，a，*p 1，* * p2)；
Return? 0;
}
