Explain how will you allocate memory dynamically for a two dimensional array of floating point numbers.
To allocate memory dynamically for a two-dimensional array of floating point numbers in C, we can use pointers and the `malloc()` function. The first step is to allocate memory for the array of pointers, where each pointer will represent a row. Then, for each row, we allocate memory to hold the elements (columns) of that row. _________ _____ ______ ________ __________ _____.

Given an integer n, what does the following function compute?
int function(int n)
{
int i;
for(i = 0; n != 0; n %=10, i++)
return i;
}
How would you differentiate between the terms pointer to an array and array of pointers? Give proper examples.
zWrite a C program which reads a line of text from keyboard, and writes the line to a file with lower case letters converted to upper case and vice-versa.
Parenthesise the following C statement for its proper evaluation.
