scanf("%d%d",&a,&b);这样书写对不对?是啥意思啊

while(scanf(%d%d,&a,&b)! scanf(%d%d,&a, scanf（%d%d,&a,&b）；%d%d scanf(%d %d,&a, &b) != EOF是什么意思 scanf(%d, 有定义char ch,s[30];int a,b;下列输入语正确的是A.scanf(“%d%f”,&a,&b); B.scanf(“%s%c”,&s,&ch);C.scanf(“%d,%s”,&ch,s); D.scanf(“%d%c”,a,ch) scanf(〃%d,%d〃,&a, while( scanf(%d%d%d,&a,&b,&c)!=EOF)是什么意思? #include void main() { int a,b; float x,y; char c1,c2; scanf(a=%d b=%d,&a,&b); scanf(%f#includevoid main(){int a,b;float x,y;char c1,c2;scanf(a=%d b=%d,&a,&b);scanf(%f%e,&x,&y);scanf(%c%c,&c1,&c2);printf(%d%d%f%f%c%c);}老运行不正常 请 while(scanf(%d %d %ld,&a,&b,&n),a+b+n),为什么可以这样表达? #include main() {int a,b,c,t1,t2; scanf(%d%d%d,&a,&d,&c); t1=a scanf(%d%d*d%d,&a,&b,&c);这条语句会输入几个数据?scanf(%d%d*d%d,&a,&b,&c);scanf(%d%d%*d%d,&a,&b,&c);输入的时候第三个是 %*d 不会对c地址赋植.所以第一次输入数值的时候 是输入的a 第二次输入的是B第三 # include void main() {int a,b,c,t; scanf(%d%d%d,&a,&b,&c); if(a 比如：while(scanf(%d%d,&a,&b)!=EOF)这句是什么意思? scanf(%d%d,&a,&b);这样书写对不对?是啥意思啊 #include int main() { int a,b,c; scanf(%d,%d,&a,&b); printf(c=a+b ,a,b); } 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();} C语言 按大小排列#include stdio.hvoid main(){int a,b,c,d,temp;scanf(%d,%d,%d,%d,&a,&b,&c,&d);if(a
