- When any document file is opened then every point has some particular address. so there is a pointer which states that where the read operation and the write operation is going on.
- When any person writes any program to read a file or write a file then there is a need for some variable that is pointed for the reading and the write operation.
- The document which is used for the write data or read data is also designed and maintained by some software.
- Hence we can say that there are needs of some variable that point the operation of the file and it is also stated from the above question. Hence the above question statement is a true statement.

According to the given question, sales is a two-dimensional array and contains 10 rows and 7 columns wherein each component is of type integer and the variables sum and j are also of integer type.
<u>Explanation:</u>
In order to find the sum of the elements of the fifth row of sales, the correct piece of code should be:
sum=0;
for(j=0;j<7;j++)
sum=sum+sales[4][j];
The indexing in an array always starts from zero, therefore, to calculate the sum of the fifth row, the user has to write 4 in the index to point to the fifth row.
Answer:
120
Explanation:
This question is basically asking how many ways can we arrange 5 sizes of shirts if they come in 4 colors.
5 permutation of 4
To find permutation, we use the formula
P(n, r) = n! / (n - r)!
Where
n is the size of the shirts available, 5
r is the color of each shirt available, 4
P(5, 4) = 5! / (5 - 4)!
P(5, 4) = (5 * 4 * 3 * 2 * 1) / 1!
P(5, 4) = 120 / 1
P(5, 4) = 120
Therefore, the total number of shirts available is 120
