scanf("%d %d %ld",&a,&b,&n),a+b+n 这个是一个逗号表达式,scanf("%d %d %ld",&a,&b,&n)进行一步为a,b,n的输入,a+b+n的值则作为while（）里的判定条件当a+b+n==0时退出循环
否则继续输入a,b,n的值

while(scanf("%d %d %ld",&a,&b,&n),a+b+n),为什么可以这样表达? while (scanf(\"%ld %ld %ld\",&a,&b,&c) == while(scanf("%d%d",&a,&b)! 素数回文数#includemain(){ int i,n,a,b,c,d,j,count; while (scanf( while(scanf("%d%d",&a,&b)!=EOF,a||b) scanf("%d",&a); scanf("%c",&c); scanf("%d",%b); scanf("%d %c while( scanf("%d%d%d",&a,&b,&c)!=EOF)是什么意思? main( ) { long a,b,c,d,e,x; scanf("%ld",&x); a=x/10000;/*分解出比如：while(scanf("%d%d",&a,&b)!=EOF)这句是什么意思? while(scanf("%s%d",a,&n)==2)什么意思 while (scanf("%d%d", &m, &n))什么意思? main () {int m,n; scanf ("%d%d",&m,&n); while (m!=n) { while
