you can try it by using matrix multiplication(also sum is given)........... the code is given below...
#include<stdio.h>
#include<conio.h>
void main()
{
int i, j, k, r1, r2, c1, c2, sum1;
int m1[10][10], m2[10][10], sum[10][10], mult[10][10];
printf("\n Enter the no of rows & column for matrix m1: ");
scanf("%d %d", &r1, &c1);
printf("\n Enter the elements for matrix m1 row wise: ");
for(i=0;i<r1;i++)
{
for(j=0;j<c1;j++)
scanf("%d", &m1[i][j]);
}
printf("\n Enter the no of row & column for matrix m2 :");
scanf("%d %d", &r2, &c2);

What is matrix programming in C programming?
C Examples on Matrix OperationsA matrix is a rectangular array of numbers or symbols arranged in rows and columns. The following section contains a list of C programs which perform the operations of Addition, Subtraction and Multiplication on the 2 matrices. The section also deals with evaluating the transpose of a given matrix. The transpose of a matrix is the interchange of rows and columns.The section also has programs on finding the trace of 2 matrices, calculating the sum and difference of two matrices. It also has a C program which is used to perform multiplication of a matrix using recursion.C Program to Calculate the Addition or Subtraction & Trace of 2 MatricesC Program to Find the Transpose of a given MatrixC Program to Compute the Product of Two MatricesC Program to Calculate the Sum & Difference of the MatricesC Program to Perform Matrix Multiplication using Recursion

C program was introduced in the year?
c program was introduced in the year 1972 by Dennis RitchieNo, it was the C language, not the C program.
C program on left factoring in compiler design?

Program to display multiplication of two matrix?
The matrix multiplication in c language : c program is used to multiply matrices with two dimensional array. This program multiplies two matrices which will be entered by the user.

Which property of polynomial multiplication says that the product of two polynomials is always a polynomial?
That property is called CLOSURE.
C program for matrix multiplication using dynamic memory alllocation?

Are polynomial expressions closed under multiplication?
Yes, because there is no way of multiplying two polynomials to get something that isn't a polynomial.
What is a polynomial multiplication with a quotient of x 3 and a remainder of 2?
To get a quotient and a remainder, you would need to do a division, not a multiplication.
If polynomial is not any number then how will you define a polynomial?
An expression made with constants, variables and exponents, which are combined using addition, subtraction and multiplication, ... but not division.
What is the answer called when 2 or more polynomials are multipiled?
A polynomial is any number of the form Ax^n + Bx^n-1 + ... + c. So, multiplying numbers with exponents with any other numbers with exponents in polynomials only results in another, larger polynomial. Since this is multiplication, you could call the resultant polynomial a product.
What does it mean for a polynomial to be closed under addition subtraction and multiplication?
It means that you can do any of those operations, and again get a number from the set - in this case, a polynomial. Note that if you divide a polynomial by another polynomial, you will NOT always get a polynomial, so the set of polynomials is not closed under division.
Is the factor of polynomials means to rewrite it as multiplication?
Yes. Factoring a polynomial means to separate it into smaller factors, which, when multiplied together, give you the original polynomial.
What is the multiplication property of multiplication?
a*(b + c) = a*b + a*c
