Consider the following program in C language:

#include <stdio.h>

main()
{
   int i;
   int*pi = &i; 
   
   scanf("%d",pi);
   printf("%d\n", i+5);
}

Which one of the following statements is TRUE?

View worked solution

Answer: D

Let us analyze the execution of the given C program step-by-step:

Variable Declaration:
```
int i;
```
This declares an integer variable i.
Pointer Initialization:
```
int* pi = &i;
```
This declares an integer pointer pi and initializes it with the address of i (i.e., &i). Thus, pi points to the memory location of i.
Reading Input:
```
scanf("%d", pi);
```
The scanf function expects the address of the variable where the input integer should be stored. Since pi holds the address of i (equivalent to &i), the integer entered by the user is successfully stored in the variable i.
Printing Output:
```
printf("%d\n", i + 5);
```
This prints the value stored in i plus $5$ $5$ .

Thus, the program compiles and executes successfully, printing a value that is $5$ more than the integer value entered by the user.

Therefore, the correct option is D.
