Just for fun i tried this.

float abc[50][50];
float cba[50][50];
int main(void)
{
 abc[1][2]=59.72;
 swap(abc,cba);
 printf("%f\n",abc[1][2]);
 printf("%f\n",cba[1][2]);
 return 0;
}
swap (void* A, void* B)
{
 void* i=A;
 A=B;
 B=i;
}

This is the output:
59.720001
0.000000

so,IT DON'T WERK........
 

The real problem in this is that i need to 
change the value of a constant pointer...

There has to be a way to do this.
