/*
MAE 9: Final Exam, Fall 2005
Due on Monday, December 5th, before 10:00 pm
Use this template as a starting point for your final. Add code for the
3 void functions at the bottom. Add additional functions after each prob().
For example, if you are adding a function for prob2(), write the function
bewteeen prob2() and prob3() below. The function prototypes can be in any
order. You do not need to change anything in main(). Your entire final
should be one large C program, and should be turned in as usual.

The assigned problems are:
prob1(): Compute the first 35 elements of an integer sequence
defined by a recursive relation:
n[i+2] = 2*n[i+1]-n[i]+5, with n[0]=1 and n[1]=2.
Print the computed elements on the terminal screen, 5 per line,
using the format %10d.
Then, compute the quantity
R = (n[25]-n[24])/n[25]
by using double floating-point values and print the result on
the terminal screen by using the format %11.5f.
......................
prob2(): By using the functions calloc() or malloc() allocate memory
to store n integer values in int *v. Suppose n=6. Enter 6 integer
values randomly from the keyboard and save them in int v[]. Print the
components of the vector v[] on the screen.
Rearrange the components of v[] in ascending order starting from
the smallest number. Print the components of rearranged v[] on
the screen and in the data file "vector.dat".
...........................
prob3(): The elements of the (4x3) matrix are b[i][j]=1.5*(i+2)*(j+1).
Use the calloc function and pointer to pointer **b to allocate
the memory space for the matrix. Pass the pointer to pointer to
the function trans_matrix(double **b,int rows,int cols) which will transpose
the matrix. Print the original and the transpose matrix. Print the
memory address of b[1][2].
