40.arrays: Specification17-20

 Specification17:

Accept two vectors of same size, store addition of them into another vector and print the sum. (Addition of two vectors)

 

Logic:

We can’t directly add any two vectors.

We need to add individual elements and store into another vector. (c[i]=a[i]+b[i])

 

 

                                                                                 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Program:

#include<stdio.h>

void main()

{

int i,n,a[50],b[50],c[50];

 

printf("Enter the size of vector:");

scanf("%d",&n);

printf("Enter %d elements into 1^st vector:\n",n);

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

  scanf("%d",&a[i]);

printf("Enter %d elements into 2^st vector:\n",n);

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

  scanf("%d",&b[i]);

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

   c[i]=a[i]+b[i];

printf("Sum of two vectors:\n");

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

   printf("%5d",c[i]);

 

}

 

Execution:

Enter the size of vector: 6

Enter 6 elements into 1^st vector:

12   23   10   8   16   22

Enter 6 elements into 2^nd vector:

7     8     19   24   15   20

Sum of two vectors:

19   31   29   32   31   42

Specification18:

Accept "n" elements into an array, sort the elements in ascending order and print the resultant array.

 

Logic:

1. Select element by element as key element.
2. From the next element to the key element compare the elements with the key element.
3. If element is less than the key element then interchange with the key element and continue until the end of array.
4. Continue the same procedure until the end of array.

void main()

{

int n,i,k,temp,a[50];

 

printf("How many elements?");

scanf("%d",&n);

printf("Enter %d elements:\n",n);

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

   scanf("%d",&a[i]);

for(k=0;k<n-1;k++)

   for(i=k+1;i<n;i++)

    if(a[i]<a[k])

    {

         temp=a[i];

         a[i]=a[k];

         a[k]=temp;

    }

printf("Elements of array in ascending order:\n");

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

   printf("%5d",a[i]);

 

}

 

Execution:

How many elements? 6

Enter 6 elements:

34   56   12   45   18   23

Elements of array in ascending order:

34   56   12   45   18   23

 

Specification19:

Accept "n" elements into an array, arrange them in descending order and print the resultant array.

 

Program:

#include<stdio.h>

void main()

{

int n,i,k,temp,a[50];

 

printf("How many elements?");

scanf("%d",&n);

printf("Enter %d elements:\n",n);

Execution:

How many elements? 6

Enter 6 elements:

34   56   12   45   18   23

Elements of array in ascending order:

56   45   34   23   18   12

 

Specification20:

Accept "n" elements into two arrays and print whether they are equal or not.

 

Logic:

The flag is stored with 1 by default.

We will check for inequality by checking element by element in both the arrays.

If inequality is found then 0 is stored in flag.

At the end of loop if flag has 1 then both the arrays are equal otherwise not equal.

 

Program:

#include<stdio.h>

void main()

{

int i,n,flag,a[50],b[50];

 

printf("How many elements?");

scanf("%d",&n);

printf("Enter %d elements into 1^st array:\n",n);

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

   scanf("%d",&a[i]);

printf("Enter %d elements into 2nd array:\n",n);

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

   scanf("%d",&b[i]);

flag=1;

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

   {

        flag=0;

        break;

   }

if(flag)

  printf("Equals");

else

  printf("Not equal");

 

}

 

Execution:

How many elements? 5
