if ( x< y ) { t=x; x=y; y=t; } 怎么理解呢?

if ( x< y ) { t=x; x=y; y=t; } 怎么理解呢? #include void swap(int a,int b){ int t;if(a>b)t=a,a=b,b=t;}void main(){ int x=13,y=11,z=12;if(x>y) swap(x,y);if(x>z) swap(x,z);if(y>z) swap(y,z);printf(%d %d %d ,x,y,z);} 这个C语言程序怎么解呀?求两个正整数x和y的最大公约数.求两个正整数x和y的最大公约数#include #include int main( ){ int x,y,t,i;scanf(%d,%d,&x,&y);if(x > y) {t = x; x = y; y = t;}for( _______________ ){ if( x%i==0 && y if(x!=y) return((x+y)/2)啥意思? 微分方程 矩阵 x'(t)=x(t)+y(t)+2t y'(t)=x(t)+y(t)-2t Dim x%:If x Then y = x Else y = x + 1:Print y为什么结果是1?If x Then y = x Else y = x + If two even number x,y satisfy equation x×x+100=y×y,x #includeint main(void){int x,y,t,n,flag=1,s,i;while( scanf(%d%d,&x,&y)==2 ){if(x>y){t=x;x=y;y=t;}if(x==0&&y==0) continue;for(n=x;n if(z=y=x) int main() { int x,y,z,t; scanf(%d,%d,%d,&x,&y,&z); if(x>y) {t=x;x=y;y=t;}/*交换x,y的值*/ if(x>z)为什么输出以后现实的最小值是个负数. if (w!=0 && (x+y)/wJAVA if(x) y+=2是什么意思 #includemain(){int x=1,y=2,z=3;if(x>y)if(y int x=1,y=2,z=3if (x>y)if(y 填空题,括号内#include #include #include void main(){ int x,y,t,max,min,i,n1,n2;printf(Please enter two numbers:);scanf(%d,%d,&x,&y);if(x > y){t = x; x = y; y = t;}n1=x; n2=y;t = n2 % n1;//max = ();min = x * y / max ;printf(max is :%d ,ma C语言中If(!x) y ++; x) 求自然数对数Private Sub Command1_Click()For x = 1 To 100For y = 1 To 100If x < y Then t = x:x = y:y = tIf x + y = (Sqr(x + y)) ^ 2 And x - y = (Sqr(x - y)) ^ 2 ThenList1.AddItem Format(x,@@@@) & Format(y,@@@@)End IfNextNextEnd Subx < y Then 请高手给予程序讲解,特别对于if(f){x=x*10+c;} else{y=y+c/t;t=t*10;}} double fun(char*s) { double x=0,y=0,t=10; int c,f=1; while(*s) { if(*s=='.') f=0; else { c=*s-'0';if(f){x=x*10+c;}else{y=y+c/t;t=t*10;}}s++;}return x+y;}
