# Subtract two matrix by R4R Team

Matrix:
-Multidimensional Array
-Matrix consist of the rows and columns.

Syntax-
array[row][column]
//Martix with numbers of rows and columns

Subtraction of two matrix:
Condition: order of both matrix must be same

Example-
a[2,3]={1,2,3,4,5,6}
b[2,3]={1,1,1,1,1,1}
a-b={0,1,2,3,4,5}

program-

#include< stdio.h>
int main()
{
int a[10][10],b[10][10],r1,c1,r2,c2,i,j;
printf("Enter rows and columns for Matrix_1\n");
scanf("%d%d",&r1,&c1);
//input in matrix_1
printf("Enter %d number in matrix_1\n",r1*c1);
for(i=0;i< r1;i++)
{
for(j=0;j< c1;j++){
scanf("%d",&a[i][j]);
}
}
printf("Enter rows and columns for Matrix_2\n");
scanf("%d%d",&r2,&c2);
//input in matrix_2
printf("Enter %d number in matrix_2\n",r2*c2);
for(i=0;i< r2;i++)
{
for(j=0;j< c2;j++){
scanf("%d",&b[i][j]);
}
}
//Subtract matrix_1 by matrix_2
if(r1==r2 && c1==c2)
{
printf("Resultn");
for(i=0;i< r1;i++)
{
for(j=0;j< c1;j++)
{
printf("%d ",a[i][j]-b[i][j]);
}
printf("\n");
}
}
else
printf("Subtraction is not possible between these matrix");
}

output-

Enter rows and columns in matrix_1
2 2
Enter 4 number in matrix_1
1 2 3 4
Enter rows and columns in matrix_2
3 3
Enter 9 number in matrix_2
1 2 3 4 5 6 7 8 9
Subtraction is not possible betweeen these matrix

Enter rows and columns in matrix_1
2 2
Enter 4 number in matrix_1
1 2 3 4
Enter rows and columns in matrix_2
2 2
Enter 4 number in matrix_2
4 4 4 4
Result
3 2
1 0
