Implement function prt_triangle that takes an integer
n from the user and prints a n-row triangle using
asterisk. It first prompts the message "Enter the size
of the triangle:", takes a number from the user as
input, and then prints the triangle. You should use the
function printf to display the message, allocate
memory for one null-terminated strings of length up
to 2 characters using char rows[3], and then use the
function fgets to read the input into the strings, e.g.
fgets(rows, sizeof(rows), stdin). You also need to
declare one integer variable nrows using int nrows,
and use the function atoi to convert the string rows
into the integer nrows. You can use the command
man atoi to find more information on how to use the
atoi function. A sample execution of the function is as
below:Enter the size of the triangle: 5
