求line(x 6,y 19,x 10,y 17);scanf("%d",

int x,y; scanf("%d",&x); if(x if(x!=y) scanf("%d",&x) else scanf("%d",&y)这个if语句形式对吗?为什么? #include main( ) {int x,y; scanf("%2d%ld",&x,&y); printf("%d C语句while(scanf("%d%d",&x,&y)==2&&(x!=0||y! scanf("%2d%*2d%1d",&x,&y);是什么意思%2d%*2d%1d int main() { int x,y,z,t; scanf("%d,%d,%d",&x,&y,&z); if(x>y C语言求绝对值求一个数的绝对值.main(){main(){int x,y;scanf("%d",&x);if (x0) c语言的问题#includevoid main(){ int x,y; scanf("%d",x); if(x>2) i 编程分段函数#include void main(){int x,y;scanf("%d",&x);if(x 这道题哪里出错了,main() { int x; float y; scanf ("%d",x); if (x 请解释下这个程序main() {int x,y; scanf("%d",&x); y=x > 12?x+10:x一12; C语言中一些符号什么意思?scanf("%d %d",&x,&y)中%d,
