1. Write a program to find sum of two fractions
void input(int *num1, int *den1, int *num2, int *den2);
void add(int num1,int den1, int num2, int den2, int *num3, int *den3);
void output(int num1, int den1, int num2, int den2, int num3, int den3);
input:
1 4
1 2
output:
1/2 + 1/4 = 3/4

2. Write a program to find the smallest of three fractions.
struct _fraction
{
int num,den;
};
typedef _fraction Fraction
Fraction input_fraction();
Fraction Largest_fraction(Fraction f1, Fraction f2, Fraction f3)
void output(Fraction f1, Fraction f2, Fraction f3, Fraction largest)

3. Write a program find the nCr given n and r.
int input_n_and_r(int *n, int *r)
int ncr(int n, int r);
void output(int n, int r, int result);

4. Write a program to evaluate a polynomial at a given point using horners method.
int input_degree();
float input_x();
void input_coefficients(int n, float a[n]);
float evaluate_polynomial(int n, float a[n], float x);
void out_put(int n, float a[n], float x, float result);
input:
1 1 1
output:
1+1*x + 1*x^2 at 1.000000 is 1.000000

5. write a program to find the index of the largest number in an array.
int input_size();
void input_array(int n, int a[n]);
int find_largest(int n, int a[n]);
void out_put(int n, int a[n], int largest);

6. Write a program to count the number of words in a string using strtok ( string.h)
void input_string(char *a);
int count_words(char *string);
void output(char *string, int no_words);
input:
hello world hello

output:
3

7. Write a program to add two fractions.
struct _fraction
{
int num,den;
};
typedef _fraction Fraction;
int find_gcd(int a, int b);
Fraction input_fraction();
Fraction add_fractions(Fraction f1, Fraction f2)
void output(Fraction f1, Fraction f2, Fraction f3, Fraction sum)

8. Write program to add n fractions
struct _fraction
{
int num,den;
};
typedef _fraction Fraction;
int find_gcd(int a, int b);
Fraction input_fraction();
void input_in_fractions(int n, Fraction f[n]);
Fraction add_fractions(Fraction f1, Fraction f2);
Fraction add_n_fractions(int n,Fraction f[n]);
void output(int n, Fraction f[n], Fraction sum);
