Loop an If condition until .. ?

Is it possible to have a code that would do my math until the results are between 50 and 200 ?
My equation can go very high and I have to work with either /2 or *2 until I get between those 2 targets. As high as 11 times doing /2 (hence the 11 if)

Could you help me please ?

Code:

  switch (choix)
  {  
   case 1:        
    printf("f: "); 
    scanf("%lf", &B);
    C = A/(1/B);
    if(C<50) C=2*C;
    if(C>200) C=C/2;   
    if(C<50) C=2*C;
    if(C>200) C=C/2;
    if(C<50) C=2*C;
    if(C>200) C=C/2;
    if(C<50) C=2*C;
    if(C>200) C=C/2;   
    if(C<50) C=2*C;
    if(C>200) C=C/2;
    if(C<50) C=2*C;
    if(C>200) C=C/2;
    if(C<50) C=2*C;
    if(C>200) C=C/2;
    if(C<50) C=2*C;
    if(C>200) C=C/2;
    if(C<50) C=2*C;
    if(C>200) C=C/2;
    if(C<50) C=2*C;
    if(C>200) C=C/2;
    if(C<50) C=2*C;
    if(C>200) C=C/2;
    printf("t = %.10f \n\n",C);
    break;

Code:

while ( C<50 || C>200 ) {
    if(C<50) C=2*C;
    if(C>200) C=C/2;   
}

Or even

Code:

while ( C < 50 ) C = C * 2;
while ( C > 200 ) C = C / 2;
