改变点坐标

Question

I need help solving this problem in my mind so if anyone had a similar problem it would help me.

We have one point in the function main , which represents the center of the coordinate system with a certain name O(0,0) , how to use the function function to change that point in A(1,2) ?

Here's my code:

struct Point {char m;float x, y;};
void function(struct Point t, char s,float array[2])
{
   t.m=s;
   t.x=array[0];
   t.y=array[1];

}
int main()
{
   float array[]={1,2};
   struct Point t1={'O',0,0};;
   function(t1,'A',array);
   printf("%c(%.2f,%.2f)",t1.m,t1.x,t1.y);
   return 0;
}

Note the function function must have a prototype function(struct Point t,char s,float array[2]);

Thanks in advance!

Best regards!

It cannot be done. The provided function prototype provides no way to return any modified values to its callers other than floats.
