A function in C is a block of code that performs a specific task. It is a reusable code module that can be called by other parts of a program. Functions help in modular programming, where complex programs are divided into smaller, simpler parts that can be easily understood and maintained.

OUPUT:

enter two number 4 5

the sum of two numbers is 9

PROGRAMS:

#include<stdio.h>

int sum(int*,int*);

int main()

{

int a,b;

printf("enter two number ");

scanf("%d%d",&a,&b);

int...

Recursion in C is a process where a function calls itself as a subroutine in order to solve a particular problem. In this process, the function repeats itself with different arguments until a specific termination condition.

OUPUT:

Enter any number 6

factorial is 720

PROGRAMS:

#include<stdio.h>

int fact (int);

int main()

{

int n,f;

printf("Enter any number ");

scanf("%d",&n);

f = fact(n);

printf("factorial is %d",f);

return 0;

}

int fact (int n)

{

if (n<=1)

return 1;

else
