scanf("%d%d",&a,&b);这样书写对不对?是啥意思啊

scanf("%d",&a); scanf("%c",&c); scanf("%d",%b); scanf("%d %c while(scanf("%d%d",&a,&b)! scanf("%d%d",&a, while(scanf("%d %d %ld",&a,&b,&n),a+b+n),为什么可以这样表达? C语言scanf("%d,&a[i][j]");什么意思啊 while(scanf("%d%d",&a,&b)!=EOF,a||b) scanf("%d %d",&a, &b) != EOF是什么意思 scanf("%d", scanf("%d%d*d%d",&a,&b,&c);这条语句会输入几个数据? #include main() { double a,b,c,s,v; scanf("%d,%d,%d",&a,&b,& # include void main() {int a,b,c,t; scanf("%d%d%d",&a,&b,&c) #include void main(){int a,b;scanf("%d %d" ,a,b);printf("%d
