if(x!=y) scanf("%d",&x) else scanf("%d",&y)这个if语句形式对吗?为什么?

if(x!=y) scanf("%d",&x) else scanf("%d",&y)这个if语句形式对吗?为什么? int x,y; scanf("%d",&x); if(x main() { float x,y; scanf(%f,&x); if(x>=0) y=x; else y=-x; p int main() { int x,y,z,t; scanf("%d,%d,%d",&x,&y,&z); if(x>y 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 C语句while(scanf("%d%d",&x,&y)==2&&(x!=0||y! #include main() { float x,y; scanf("%f",&x); if(x #include mian() { float x,y; scanf("%f",&x); if(x>=0) { if(x 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) main ( ) {int y ,f ; scanf ( "% d ",&y ) ; if ( y % 400 = =
