while (scanf("%d%d",&w,&h),在程序中是一个已经定义的数嘛?

while(scanf(%d%d,&a,&b)! while (scanf(%d/%d,&i,&j), while(scanf(%d,&m)!=EOF) while (scanf(%d%d, &m, &n))什么意思? scanf(%d, while(scanf(%d,&n)&&n!=-1)和while(scanf(%d,&n)!=-1)有什么区别》》具体的解释 scanf(%d%d,&a, while( scanf(%d%d%d,&a,&b,&c)!=EOF)是什么意思? C语句while(scanf(%d%d,&x,&y)==2&&(x!=0||y! while(scanf(%d %d %ld,&a,&b,&n),a+b+n),为什么可以这样表达? while(scanf(%d%d,&x,&y)==2&&(x!=0||y!=0)) 比如：while(scanf(%d%d,&a,&b)!=EOF)这句是什么意思? while (scanf(%d%d,&w,&h),在程序中是一个已经定义的数嘛? ACM规则:while(scanf(%s%d,s,&n)!=EOF){//.}while(scanf(%s%d,s,&n)!=EOF){//.}//请问这句话到底是拿来干什么的? 请问在c语言里：scanf（%d,&m）;while(i 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? #include < stdio.h > main() { int m,n; scanf(%d%d,&m,&n); while (m!=n) { while(m>n) m=m-n;while(m
