Question

If the input is negative, make numItemsPointer be null. Otherwise, make numItemsPointer point to numItems and multiply the value to which numItemsPointer points by 10. Ex: If the user enters 99, the output should be: Items: 990

Answer 1

To implement the desired functionality, you can use a conditional statement in your code. If the input is negative, you can assign a value of null to the variable numItemsPointer. If the input is positive, you can assign the memory address of the numItems variable to the numItemsPointer variable and then multiply the value at that memory address by 10.

Step-by-step explanation:

To implement the desired functionality, you can use a conditional statement in your code. If the input is negative, you can assign a value of null to the variable numItemsPointer. If the input is positive, you can assign the memory address of the numItems variable to the numItemsPointer variable and then multiply the value at that memory address by 10.

Example Code:

// Assuming userInput contains the input value
if(userInput < 0) {
numItemsPointer = null;
} else {
numItemsPointer = &numItems;
*numItemsPointer = *numItemsPointer * 10;
}
