Exercise 6

Write a C program to implement sorting of an array of elements.

SOURCE CODE:

/*Program to implement sorting of an array of elements.*/

#include<stdio.h>

#include<conio.h>

void main()

{

 int a[30],n,i,j,temp;

 clrscr();

 printf("\nEnter the array size:");

 scanf("%d",&n);

 printf("\nEnter %d elements:\n",n);

 for(i=0;i<n;i++)

  scanf("%d",&a[i]);

 printf("\nBefore sorting array is:\n");

 for(i=0;i<n;i++)

  printf("%d\t",a[i]);

 printf("\nAfter sorting array is:\n");

 for(i=0;i<n;i++)

 {

  for(j=i+1;j<n;j++)

  {

   if(a[i]>a[j])

   {

    temp=a[i];

    a[i]=a[j];

    a[j]=temp;

   }

  }

 }

 for(i=0;i<n;i++)

  printf("%d\t",a[i]);

}

OUTPUT:

Write a C program to input two m x n matrices, check the compatibility and perform addition them.

SOURCE CODE:

/*Program to perform sum of two matrices*/

#include<stdio.h>

#include<conio.h>

void main()

{

 int a[20][20],b[20][20],c[20][20],i,j,r1,c1,r2,c2;

 clrscr();

 printf("Enter first matrix row and column size:");

 scanf("%d%d",&r1,&c1);

 printf("Enter second matrix row and column size:");

 scanf("%d%d",&r2,&c2);

 if((r1!=r2)||(c1!=c2))

  printf("\nMatrix addition is not possible.");

 else

 {

  printf("\nEnter first matrix elements %d X %d:\n",r1,c1);

  for(i=0;i<r1;i++)

   for(j=0;j<c1;j++)

    scanf("%d",&a[i][j]);

  printf("\nEnter second matrix elements %d X %d:\n",r2,c2);

  for(i=0;i<r2;i++)

   for(j=0;j<c2;j++)

    scanf("%d",&b[i][j]);

  for(i=0;i<r1;i++)

  {

   for(j=0;j<c1;j++)

   {

    c[i][j]=a[i][j]+b[i][j];

   }

  }

  printf("\n::Addition of Two Matrices is::\n");

  for(i=0;i<r1;i++)

  {

   for(j=0;j<c1;j++)

   {

    printf("%d\t",c[i][j]);

   }

   printf("\n");

  }

 }

}

OUTPUT:

Write a C program to input two m x n matrices, check the compatibility and perform multiplication them.

SOURCE CODE:

/*Program to perform product of two matrices*/

#include<stdio.h>

#include<conio.h>

void main()

{

 int a[20][20],b[20][20],c[20][20],i,j,k,r1,c1,r2,c2;

 clrscr();

 printf("Enter first matrix row and column size:");

 scanf("%d%d",&r1,&c1);

 printf("Enter second matrix row and column size:");

 scanf("%d%d",&r2,&c2);

 if(c1!=r2)

  printf("\nMatrix multiplication is not possible.");

 else

 {

  printf("\nEnter first matrix elements %d X %d:\n",r1,c1);

  for(i=0;i<r1;i++)

   for(j=0;j<c1;j++)

    scanf("%d",&a[i][j]);

  printf("\nEnter second matrix elements %d X %d:\n",r2,c2);

  for(i=0;i<r2;i++)

   for(j=0;j<c2;j++)

    scanf("%d",&b[i][j]);

  for(i=0;i<r1;i++)

  {

   for(j=0;j<c2;j++)

   {

    c[i][j]=0;

    for(k=0;k<c1;k++)

    {

     c[i][j]=c[i][j]+a[i][k]*b[k][j];

    }

   }

  }

  printf("\n::Multiplication of Two Matrices is::\n");

  for(i=0;i<r1;i++)

  {

   for(j=0;j<c2;j++)

   {

    printf("%d\t",c[i][j]);

   }

   printf("\n");

  }

 }

}
