程序设计题：1、 有一个函数：y= 写程序,输入x的值,输出y相应的值.

C :
int input()
{
int x;
printf("input %d",x);
scanf("%d",&x);
return x;//x*x)
}
int main()
{
int y;
y=input();
printf("input %d",y);
}
Pascal:
program input ;
var x,y :integer;
readln(x);
writeln(x)
y:=x;
writeln(y);
end;
Basic:
dim x as integer,y as integer
read x
print x,y
end
