Storing numbers in link list

Problem statement
Write a c program to store values using link list, your program should store the values in order they are entered and the print the values. total number of inputs will be given by user,
for example

3
5
1
then your program should print
1
2
3
5
1
and store in the same manner only, i.e. the number which will be entered in the list will be in the last of the list

Calculatinf solution of an equation using Bisection Method

Problem statement
Write a program that uses the bisection algorithm to find  a root of 
the equation x² − 2 = 0. 
The method of successive bisection works as follows: Start with a lower bound l and an 
upper bound u such that  f(l)*f(u) > 0, ie, f(l) and f(u) are of opposite signs. Then there is 
a foot of f(x) between l and u. Write a loop where in each iteration, you compute the 
middlepoint (mid) of the current interval [l, u]. Evaluate f(mid), and based on the sign of 
f(mid), change the current interval to [l, mid] or to [mid, u]. The loop terminates when 
width of the interval becomes smaller than  10⁻⁶

Starting address of words in a line

Problem statement
Write a c program to do the following
Consider the interface of a recursive function:
int wordIndex(char *x, int ind[]).
It takes a string and an int array as parameters.
It returns the word count(i.e. the number of words in that line). The int array after
return will hold the starting indexes of words in
the string.
For Example 
Consider the string
"This string has five words".
Your program should say that this line contains 5 words,and starting address of words are 1,5,...

Finding out SADDLE point

Problem statement

Write a c program to find out saddle point of a metrics
For a given m × n matrix A, the (i, j) the element is said to be a saddle
point if it is the maximum in row i and minimum in column j, or
minimum in row i and maximum in column j.
(a) Write a function int saddle (A, i, j) to test if the (i, j) the element
of the given matrix A is a saddle point or not. Choose the
function prototype in a suitable way, and use additional parameters,
if necessary. If the element is a saddle point, the function
must return 1; if not, it must return 0.
(b) Write a main function that would first read in an m × n matrix
A. Then all the saddle points of the matrix (along with their
positions) would be printed, using the function saddle(). Both
the given matrix and also the output should be printed in properly
formatted form.

(

     For a given m × n matrix A, the (i, j) the element is said to be a saddle
     point if it is the maximum in row i and minimum in column j, or
     minimum in row i and maximum in column j.
