Assume that we are employing the cooperative approach to switch between processes running on the CPU (i.e., no timer interrupts). We have included a function yield() that allows the process to transfer control of the CPU to the operating system. Which of the following code segments can keep control of the CPU from the operating system indefinitely?

Accepted Answer

int magicNum; 
while(1){ 
  magicNum = 3520; 
} 
yield();

Answer

int magicNum = 3520; 
while(1){ 
  printf("The Magic Number is %d", magicNum); 
} 
yield();

Answer

int magicNum; 
while(1){
  scanf("%d", &magicNum);
} 
yield();

Answer

int magicNum, denom, quo; 
magicNum = 3520; 
denom = magicNum; 
while(1){ 
  quo = magicNum / denom; 
  denom--; 
} 
yield();
