Question

I have questions declare of array several form.

Question .

Write array declarations for the following data:

i) x = An array of 15 double type numbers
ii) ? = [ 1 0 0 2 0 0 3 0 0]
iii) word = 10 words of at most 9 characters each

iv) Z = A 5 × 10 matrix of all zeroes

THX!

language is C

Answer 1

1. double x [14];

As array indexing starts from 0. So, taking 14 as the size of the array to store 15 elements.

2. int M[] = {1,0,0,2,0,0,3,0,0};

An integer array M is declared.

3. char arr[10][9] =

                { "one",

                "two",

                "three",

                "four",

                "five",

                "six",

                "seven",

                "eight",

                "nine",

                "ten"

                };

A two-dimensional character array is declared where first dimension is for array size and second dimension is for length of string.

4. int Z[5][10] = {{0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, {0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, {0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, {0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, {0, 0, 0, 0, 0, 0, 0, 0, 0, 0}};

A two-dimensional integer array is declared where the first dimension is for row size and the second dimension is for column size.
