Answer:
Below is the explanation for the C code.
Explanation:
#include <stdio.h>
#include <stdbool.h>
int main(void) {
int userNum;
bool isPositive;
bool isEven;
scanf("%d", &userNum);
isPositive = (userNum > 0);
isEven = ((userNum % 2) == 0);
if(isPositive && isEven){
printf("Positive even number");
}
else if(isPositive &&!isEven){
printf("Positive number");
}
else{
printf("Not a positive number");
}
printf("\n");
return 0;
}
Answer:
Option (A) is the correct choice.
Explanation:
The situation describes an invalid boot disk error occurring during startup, indicating that the system fails to recognize the hard disk necessary for booting.
MBR / GPT is the partition layout that holds the essential code for system startup. Occasionally, the partition files that contain this code may become corrupt, causing an invalid boot disk error during the boot process.
Therefore, the most fitting answer is option (A).
The remaining choices are incorrect for these reasons:
- If the boot system malfunctions, it cannot produce an invalid boot disk error.
- If the files of the operating system are corrupted, the error will pertain to missing files.
- A device driver cannot influence the system's booting process.
The provided C++ code is designed to sort three double variables: void sort3(double &a, double &b, double &c). The logic within functions attempts to ensure that these values are ordered correctly, implementing swaps accordingly.
