Answer Program 1:
Output:
Explanation:
In the above program, we created two functions changeValue() and main(). The changeValue() function assigns a new value to the specified pointer. In the main() function, created a variable val initialized with 10. Then passed the address of the val variable. Then we printed the updated value of the val variable.
Answer Program 2:
Output:
Explanation:
The above program will generate a syntax error because function prototype func changeValue(v *int); is not required in the Go language.
Answer Program 3:
Output:
Explanation:
In the above program, we created a variable val and pointer ptr. Then we assigned the address of val into pointer ptr. After that, we assigned the new value to the *ptr. It will change the value of val. Then we printed the value of val and *ptr.
Answer Program 4:
Output:
Explanation:
In the above program, we created a variable val, ptr1 and ptr2. Then we assigned the address of val into pointer ptr1, and assigned the address into ptr2. After that, we assigned the new value to the **ptr2. It will change the value of val. Then we printed the value of val, *ptr1, and **ptr2.
Answer Program 5:
Output:
Explanation:
In the above program, we created a variable val, ptr. Then we assigned the address of val into pointer ptr. After that, we printed the *ptr and the 2nd character of the string val.
