OUTPUT SCREEN:

RESULT:

The result of this program is a comprehensive data in tabulated form obtained with the help of raw data provided by the user.

CONCLUSION:

The use of structures and structures within structures can be implemented to easily categorize input variables and manipulate those values by passing structures within functions.

Step1	Start of userdefined function mergex(int a[], int b[])
Step2	Initialize k=0 and i=0
Step3	Is i<x?
YES	Goto step4
NO	Goto Step8
Step4	Set c[k]=a[i]
Step5	Increase the value of k by 1
Step6	Increase the value of i by 1
Step7	Goto Step3

Step9	Is i<y?
YES	Goto step10
NO	Goto Step14
Step10	Set c[k]=b[i]
Step11	Increase the value of k by 1
Step12	Increase the value of i by 1
Step13	Goto Step9
Step14	Stop

SOURCE CODE:

#include <stdio.h>

#include <conio.h>

#define x 5

#define y 6

int c[x+y];

void main()

{

clrscr();

void mergex(int a[],int b[]);

int a[x]={1,2,3,4,5},b[y]={6,7,8,9,10,11},i;

mergex(a,b);

printf("Merged array:\n\n");

for(i=0;i<x+y;i++)

{

printf("%d ",c[i]);

}

getch();

}

void mergex(int a[],int b[])

{

int i,k=0;

for(i=0;i<x;i++)

{

c[k]=a[i];

k++;

}

for(i=0;i<y;i++)

{

c[k]=b[i];

k++;

}

}

OUTPUT SCREEN:

RESULT:

The result of this program  is the combined contents of two arrays, a[] and b[], which was stored in a third array c[] whose array size was the combined array size of the former two arrays.

CONCLUSION:
The objective of this program, to show how data are stored in arrays, was completed by fulfilling a secondary objective that required the programmer to be able to merge arrays. In any method used to solve this problem, a particular space in destination array is always given to oneparticular value in the target array. i.e. the values of arrays a[] and b[] are consecutively and successively stored inside the array c[].
