scanf("%d%d%d",&x,&y,&z); 帮忙逐个符号解释下作用

scanf(%d, int x,y; scanf(%d,&x); if(x 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();} scanf(%d%d,&a, if(x!=y) scanf(%d,&x) else scanf(%d,&y)这个if语句形式对吗?为什么? C语言中一些符号什么意思?scanf(%d %d,&x,&y)中%d, scanf(%d%d%d,&x,&y,&z); 帮忙逐个符号解释下作用 C语句while(scanf(%d%d,&x,&y)==2&&(x!=0||y! while(scanf(%d%d,&x,&y)==2&&(x!=0||y!=0)) 请问scanf(%2d%f%3*d%f%c%*d%d,&i,&x,&y,&ch,&j);中的%3*d #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 这道题哪里出错了,main() { int x; float y; scanf (%d,x); if (x 编程分段函数#include void main(){int x,y;scanf(%d,&x);if(x #include main() { int x,y; scanf(%d,&x); y=(x>=0)?((x=0)?0:1):-1; printf(x=%d,y=%d ,x #includevoid main(){ int x,y,z; printf(문용남 24호); printf(Input x:); scanf(%d,&x); printf(Input y:); scanf(%d,&y); printf(Input z:); scanf(%d,&z); printf((x+y)*(x+z)/(y%z)=%d,(x+y)*(x+z)/(y%z)); ret 在线等logo(x 28,y 21,t3,COPY_PUT);scanf(%d,elsebreak;b=temp;printf(gongyueshu:%d ,a); #include #include int main() { int x,y,sqrt; scanf (%d,&x); y=sqrt(x); if (x> 程序改错,请问怎么改?#includeint main(void){char sign;int x,y;printf(输入x运算符y:);scanf(%d%c%d,&x,& sign,&y);if(sign='*')printf(%d*%d=%d ,x,y,x*y);else if(sign='/')printf(%d/%d=%d ,x,y,x/y);else if(sign='%')printf(%dMod%d=%d
