: Consider the following code

int a; int *aPtr;

a = 9;

aPtr = &a;

printf(a is equal to %d ,a);

printf(the address of a is: %p , &a);

printf(Using the pointer, a is equal to %d , *aPtr);

printf(Using the pointer, the address of a is: %p , aPtr);

return 0;

adding functions to the above to calculate a*a and return the value: one function doing call-by- value and the other function doing call by reference

Problem 11: (1) Write a code defining an integer array of size=5 and a string array to store word, and prints all the elements of these two arrays in two separate lines.

Write a function ArrayModify that modifies the 4rd element of the integer array by making it 3 times bigger, and in main code print the original and modified elements

Write a function named ElementDouble that doubles the value of the modified 3rd element, and prints the value doubled. In main, print the 3rd element before and after calling function ElementDouble.
