scanf("%2d%*2d%1d",&x,&y);是什么意思%2d%*2d%1d输入1234567main(){int x,y;scanf("%2d%*2d%1d",&x,&y);printf("%d\n",x+y);getch();}

scanf(%d, scanf(%d%d,&a, scanf(%2d%*2d%1d,&x,&y);是什么意思%2d%*2d%1d输入1234567main(){int x,y;scanf(%2d%*2d%1d,&x,&y);printf(%d ,x+y);getch();} 请问scanf(%2d%f%3*d%f%c%*d%d,&i,&x,&y,&ch,&j);中的%3*d （1）执行语句”scanf（%d%d,&a,&b）与scanf“%d,%d&a,&b)分别表达的意思是什么?（2）设有int i=010,j=10; 则printf(%d,%d ,++i,j--);的输出是多少? （3）设a,b为字符变量,执行语句“scanf(a=%c,b=%c,&a,&b); C语句while(scanf(%d%d,&x,&y)==2&&(x!=0||y! while(scanf(%d%d,&x,&y)==2&&(x!=0||y!=0)) while(scanf(%d%d,&a,&b)! while (scanf(%d/%d,&i,&j), scanf(〃%d,%d〃,&a, scanf（%d%d,&a,&b）；%d%d main()main() { float a,b,c,d; scanf(%d%d,&a&b); c=a+b; d=a/2+b/2; printf(%d%d,a,b); 错在哪?main(){float a,b,c,d;scanf(%d%d,&a&b);c=a+b;d=a/2+b/2;printf(%d%d,a,b);getch();} while(scanf(%d,&n)&&n!=-1)和while(scanf(%d,&n)!=-1)有什么区别》》具体的解释 while(scanf(%s%d,a,&n)==2)什么意思 C语言 While (sanf(%d,scanf（）这个函数本身有值吗 ==2,3呢? while(scanf(%d,&m)!=EOF) for (scanf(%d,&m);m;m--)是什么意思 执行以下程序时输入1234567,则输出结果是?需要具体过程,#include main(){ int a=1,b;scanf(%2d%2d,&a,&b);printf(%d %d ,a,b);}
