Program of Subtraction of two Matrix.

Solution:

void main()
{
    int i,j,a[10][10],b[10][10],c[10][10],n;
    int m;
    printf("Enter number of rows: ");
    scanf("%d",&n);

    printf("Enter Number of columns: ");
    scanf("%d",&m);

//taking first array element as input 
    for(i=0;i<i++)
    {
        for(j=0;j<j++)
        {
            printf("Enter the element of first array: ");
            scanf("%d",&a[i][j]);
        }
    }


//printing first array elements
    printf("First Matrix is: \n");
    for(i=0;i<i++)
    {
        for(j=0;j<j++)
        {
            printf("%d\t",a[i][j]);
        }
        printf("\n");
    }

//taking second array element as input 

    for(i=0;i<i++)
    {
        for(j=0;j<j++)
        {
            printf("Enter the element of Second array: ");
            scanf("%d",&b[i][j]);
        }
    }
//printing second array elements

    printf("Second Matrix is: \n");
    for(i=0;i<i++)
    {
        for(j=0;j<j++)
        {
            printf("%d\t",b[i][j]);
        }
        printf("\n");
    }
//subtracting first array element from second array elements
for(i=0;i<i++)
    {
        for(j=0;j<j++)
        {
            c[i][j] = a[i][j] - b[i][j];
        }
    }

//printing the difference
    printf("Differnce of two matrix is :\n");
    for(i=0;i<i++)
    {
        for(j=0;j<j++)
        {
            printf("%d\t",c[i][j]);
        }
    printf("\n");
    }

defining a function 'give_sub' which will print the difference of two matrix

void give_sub(int a[10][10],int b[10][10],int n,int m)
{   int i,j;
    int c[10][10];
//subtracting first array element from second array elements

    for(i=0;i<i++)
    {
        for(j=0;j<j++)
        {
            c[i][j] = a[i][j] - b[i][j];
        }
    }
//printing the difference
    printf("Difference of two matrix is :\n");
    for(i=0;i<i++)
    {
        for(j=0;j<j++)
        {
            printf("%d\t",c[i][j]);
        }
    printf("\n");
    }
}

Using above define function 'give_sub()':

void main()
{
    int a[3][3] = {{1,2,3},{4,5,6},{7,8,9}};
    
    int a[3][3] = {{2,3,5}{6,7,8}{9,10,11}}
        printf("Difference of two matrix is :");
    give_sub(a,b,3,3)
}

Output1

Sum of two matrix is :
-1     -1     -2    
-2     -2     -2  
-2     -2      -2

Using above define function 'give_sub()':

void main()
{
    int a[2][2] = {{2,4,5},{6,8,10},{9,12,12}};
    
    int a[3][3] = {{1,2,3}{4,5,6}{7,8,9}};
    
    give_sub(a,b,3,3)
}

Output2

Sum of two matrix is :
1     2     2
2     3     4
2     4     3

Using above define function 'give_sub()':

void main()
{
    int a[2][2] = {{10,20},{40,50}};
    
    int a[2][2] = {{5,5},{10,10}};
    
    
    
    give_sub(a,b,2,2)
}

Output3

Sum of two matrix is :
5     15
30    40
