Directions to Solve

In the questions below the sentences have been given in Active/Passive voice. From the given alternatives, choose the one which best expresses the given sentence in Passive/Active voice.

Q1: The doctor advised the patient not to eat rice.

A The patient was being advised by the doctor that he should not rice by the doctor.

B The patient was advised by the doctor that he should not eat rice.

C The patient was advised by the doctor not to eat rice.

D The patient has been advised not to eat rice by the doctor.

Q2:
What will be the output of the program? 
#include<stdio.h>
int fun(int **ptr);

int main()
{
    int i=10;
    const int *ptr = &i;
    fun(&ptr);
    return 0;
}
int fun(int **ptr)
{
    int j = 223;
    int *temp = &j;
    printf('Before changing ptr = %5x\n', *ptr);
    const *ptr = temp;
    printf('After changing ptr = %5x\n', *ptr);
    return 0;
}

A Error: cannot convert parameter 1 from 'const int **' to 'int **'
