11: Consider the following program (This question is worth 2 marks.). int i; void foo (int x) { a[0] *= 3; i++; x *= 4; } void main() { i = 0; int a [2] = {1, 2}; foo (a[i]); } Assuming pass-by-value-result as the parameter passing method, what is the content of the variable a [0] at the end of the main program? 12: Consider the program from Question 11 again. (This question is worth 2 marks.). Assuming pass-by-reference as the parameter passing method, what is the content of the variable a [0] at the end of the main program? 13: Consider the program from Question 11 again. (This question is worth 2 marks.). Assuming pass-by-name as the parameter passing method, what is the content of the variable a [0] at the end of the main program
