CIS 15BG Answers Chapter 8 Arrays: Two Dimensional Arrays 1. Declare a 2D-array of integers, with 4 rows and 10 columns, and initialize all its elements to 0. Then assign 50 to the last element in the second from the last row and 99 to the first element in the second column. int table[4][10] = {0}; table[2][9] = 50; table[0][1] = 99; 2. Given the square two-dimensional array of integers shown below, what will be printed from the following program fragment? 50 11 12 13 20 80 22 23 30 31 25 33 40 41 42 10 for( r = 0; r < 4; r++ ) for( c = 0; c < 4; c++ ) if( r == c ) printf( %d , table[r][c] ); Output: 50 80 25 10 1

CIS 15BG Answers Chapter 8 Arrays: Two Dimensional Arrays 3. Rewrite the fragment of code in Exercise 3 as a function then call it from main. Define two parameters: the 2D-array, table , and its actual size, n . Also, give a simpler and more efficient algorithm. #include<stdio.h> #define MAX_SIZE 100 void printDiagonal(int table[][MAX_SIZE], int n); int main( void )
