A program for Matrix Addition, Subtraction using Array

 Matrix Addition & Subtraction

            In this example, we will understand to perform Matrix  Addition, Subtraction using Array and know how to write, compile and debug it in C language and also learn how to implement it in c.

        

In order to do this you will need

• Basic knowledge of c programming language.
• As well as know how to operate codeblocks.   

            An array is a fixed-size sequential collection of  elements of same data types that share a common  name.It is simply a group of data types. An array is a  derived data type.An array is used to represent a list of numbers or  a list of names.

So let's begin with our program

1.Open a codeblocks software.

2.Open new empty file.

3.Copy and paste the code from below. 

Input code-

 //PROGRAM FOR ADDITION AND SUBTRACTION OF MATTRIX BY ARRAY.  
   
 #include<stdio.h>  
 int main()  
 {  
   int a[2][2],b[2][2],c[2][2],d[2][2],i,j,k,m[2][2]={0};  
   printf("Enter first 2*2 matrix elements");  
   for(i=0;i<2;i++)  
   {  
     for(j=0;j<2;j++)  
     {  
       scanf("%d",&a[i][j]);  
     }  
   }  
   printf("Given 2*2 matrix elements of first: \n ");  
   for(i=0;i<2;i++)  
   {  
     for(j=0;j<2;j++)  
     {  
       printf("\t %d",a[i][j]);  
     }  
     printf("\n");  
   }  
   printf("Enter second 2*2 matrix elements");  
   for(i=0;i<2;i++)  
   {  
     for(j=0;j<2;j++)  
     {  
       scanf("%d",&b[i][j]);  
     }  
   }  
   printf("Given 2*2 matrix elements of second: \n ");  
   for(i=0;i<2;i++)  
   {  
     for(j=0;j<2;j++)  
     {  
       printf("\t %d",b[i][j]);  
     }  
     printf("\n");  
   }  
   //// logic for addition  
   for(i=0;i<2;i++)  
   {  
     for(j=0;j<2;j++)  
     {  
       c[i][j]=a[i][j]+b[i][j];  
     }  
   }  
   printf("Addition result: \n ");  
   for(i=0;i<2;i++)  
   {  
     for(j=0;j<2;j++)  
     {  
       printf("\t %d",c[i][j]);  
     }  
     printf("\n");  
   }  
    //// logic for Sub  
   for(i=0;i<2;i++)  
   {  
     for(j=0;j<2;j++)  
     {  
       d[i][j]=a[i][j]-b[i][j];  
     }  
   }  
   printf("Sub result: \n ");  
   for(i=0;i<2;i++)  
   {  
     for(j=0;j<2;j++)  
     {  
       printf("\t %d",d[i][j]);  
     }  
     printf("\n");  
   }  
   
   return 0;  
 }  
   

Now simply build the code. Look for any error. Now run the code.

For output enter any four number for first 2X2 matrix then press enter key & again enter any four number for second 2X2 matrix and now press enter key .
