Question

Class work # 12 / Chapter 6 –> Arrays 3 (two dimensional arrays)

Part 1:

Create a 2-by-3 integer array and initialize it with 6 integers of your choice.

Using nested for loops, display the contents of the array on the screen

Part 2: (Continue on part 1)

Display the sum of all the integers in the array that you created in part 1.

Create a function

Part 3:

Create a function that will display the elements of the array you created in part 1. Call the function from main to display the 6 integers.

What to submit:

1. The .c code for the programming questions
2. Snap shots of your answers

Answer 1

The code is written in C

#include <stdio.h>

void display(int arr[][3])
{
        for(int i=0;i<2;i++)
        {
                for(int j=0;j<3;j++)
                {
                        printf("%d ",arr[i][j]);      // Printing the array element
                }
                printf("\n");
        }
}

int find_sum(int arr[][3])
{
        int sum=0;
        for(int i=0;i<2;i++)
        {
                for(int j=0;j<3;j++)
                {
                        sum+=arr[i][j];              // Adding the value of array element to the sum
                }
        }
        return sum;
}

int main(void) {
        
        int arr[2][3];                       // PART 1 starts
        
        int number=1;
        
        for(int i=0;i<2;i++)                                   
        {
                for(int j=0;j<3;j++)
                {
                        arr[i][j]=number;            // Initializing the array element with a number
                        number++;
                        printf("%d ",arr[i][j]);     // Printing the array element
                }
                printf("\n");
        }                                    // PART 1 ends
        
        
        int sum = find_sum(arr);             // PART 2
        printf("%s","The sum is: ");
        printf("%d\n",sum);
        
        display(arr);                        // PART 3
        
}

Following is the output:
