CALL BY VALUE AND REFERENCE PROGRAMS

RECURSION ADVANTAGES AND DISADVANTAGES

What are recursive functions? What are the advantages and disadvantages of Recursive algorithms?

A recursive function is a function which calls itself.

Advantages of recursive functions:

-Avoidance of unnecessary calling of functions.

-A substitute for iteration where the iterative solution is very complex. For example to reduce the code size for Tower of Honai application, a recursive function is best suited.

- Extremely useful when applying the same solution

Disadvantages of recursive functions :

-A recursive function is often confusing.

-The exit point must be explicitly coded.

-It is difficult to trace the logic of the function.

APRIL 2016 Supply Paper Solutions

1.Addition of two numbers without using +

#include<stdio.h>

 int main() {

   int num1 = 10, num2 = 5;

   num1 = num1 - (-num2);

   printf("Sum is : %d",num1);

   return (0);

}

2.Max of three numbers using ternary operator

Void main()

{

Int a=5,b=6,c=10,max;

Max=((a>b)&&(a>c)?a:((b>c)?b:c));

Printf(“Max is %d”,max);

Getch();

}

3.print the average of n numbers in the array and pass array to function

#include<stdio.h>

void print(int a[10],int);

int main()

{

               int a[10],n=5;

               print(a,n);

               return 0;

              

}

void print(int a[10],int n)

{

               int i,sum=0;

               for(i=0;i<n;i++)

               {

                              printf("Enter element into array");

                              scanf("%d",&a[i]);

                              sum=sum+a[i];

               }

               printf("Average of array is %d",sum/n);

}
