Question

Question 5 (5 marks] Consider the syntactically correct C code below, which is missing a function print_diagonal include <stdio.h> • typedef int Table(100) (100); */• print diagonal (T, n) . Given a Table T, which will have n rows and n columns, print all of the 1 entries on the main diagonal of T (that is, entries whose row number and column number are equal). Remember to print a newline at the end. / ► / (your code from below would be placed here) */ int main() { Table T1 = { { 10, 10, 2019). { 11, 14, 2019), (111, 116, 225} }; Table T2 = {{1, 2, 3, 4), { 5, 6, 7, 8). (9,10,11,12). (13, 14, 15, 16 } }; print diagonal (T1, 3); print_diagonal (T2, 4); return 0; Once the print_diagonal function is implemented correctly, the program will generate the following output. 10 14 225 1 6 11 16 Write a definition of the function print_diagonal (including the function signature). For full marks, your implementation should work correctly on all input values, not just the ones above.

Please explain answer :D

Answer 1

The following code of the program is explained with comments. Please let me know if you have any doubts regarding the code.

Code:

#include <stdio.h>
typedef int Table[100][100];
/* print_diagonal(T,n)
 * Given a Table T, which will have n rows and n columns, print all of the
 * entries on the main diagonal of T ( that is, entries whose row number and
 * column number are equal). Remember to print a newline at the end. */
void print_diagonal(Table T,int n)
{
    // This variable is used to keep track of index of T
    int i=0;
    // Iterating over the Table T
    for(i=0;i<n;i++)
    {
        // printing the element on the main diagonal which is element at index T[i][i]
        printf("%d ",T[i][i]);
    }
    // Printing the new line
    printf("\n");
}

// This is the main function
int main()
{
    // These three Tables are the inputs that are used to test the above function
    Table T1 = { {10, 10, 2019},
                 {11, 14, 2019},
                 {111, 116, 225} };

    Table T2 = { {1, 2, 3, 4},
                 {5, 6, 7, 8},
                 {9, 10, 11, 12},
                 {13, 14, 15, 16} };

    Table T3 = { {1, 2, 3, 4, 5, 6, 7, 8, 9},
                 {10, 11, 12, 13, 14, 15, 16, 17, 18},
                 {19, 20, 21, 22, 23, 24, 25, 26, 27},
                 {28, 29, 30, 31, 32, 33, 34, 35, 36},
                 {37, 38, 39, 40, 41, 42, 43, 44, 45},
                 {46, 47, 48, 49, 50, 51, 52, 53, 54},
                 {55, 56, 57, 58, 59, 60, 61, 62, 63},
                 {64, 65, 66, 67, 68, 69, 70, 71, 72},
                 {73, 74, 75, 76, 77, 78, 79, 80, 81}};

    // Calling the function print_diagonal with above inputs
    print_diagonal(T1, 3);
    print_diagonal(T2, 4);
    print_diagonal(T3, 9);

    return 0;
}

Sample Output:

10 14 225 1 6 11 16 1 11 21 31 41 51 61 71 81 Process finished with exit code o
