Big Quiz 2 Time: 50 minutes Notes: - Implement each problem in a different file - Implement Problem1 - Implement any two problems from 2, 3 and 4 <File Name: BigQuiz1.c> 1. The following program asks the user to enter the scores of 6 students and computes their average. However, there are some bugs in it, please fix. #include<stdio.h> int * getValue(void) { static int a[6]; int i; for (i=1; i<6; i++) scanf("%d", a++); return a; } int main(void) { int j, sum; int *score; printf("Enter the 6 scores:"); score = getValue (); for (j=1; j<6; j++) sum += &score[j]; printf("Average score is: %.2f\n", sum/6); return 0; } <File Name: BigQuiz2.c> 2. Write the following function: Function name: WhichTriangle Argument Names and Types: sides (integer array indicating length of the three sides), perimeter (pointer to an integer) Returns: an integer, 0 if the triangle is scalene (all sides different), 1 if it is equilateral, 2 if only two sides are equal. Requirement: Cannot use array brackets inside the function <File Name: BigQuiz3.c> 3. Implement a program that asks the user to input a positive value n, then calculate the value of 1*2+2*3+3*4+...+(n-1)*n by using a recursive function with the prototype: void func(int n); Do not just print out the solution, print the sequence of numbers as well [i.e. for n = 4, print "1*2+2*3+3*4 = 20"] **No loops are allowed. <File Name: BigQuiz4.c> 4. Given the following declarations, convert each statement below to an equivalent statement without using square brackets, []. /* declarations */ int a, b[3] = {2, 4, 6}, c[2] = {0, 1}; int *ptr1; /* statements */ ptr1 = &a[0]; a = c[1]; b[2] = a;
