Matrix addition in C: C program to add two matrices, i.e., compute the sum of two matrices and then print it. Firstly a user will be asked to enter the order of matrix (number of rows and columns) and then two matrices. For example, if a user input order as 2, 2, i.e., two rows and two columns and matrices as

First matrix:

1 2

3 4

Second matrix:

4 5

-1 5

then the output of the program (Summation of the two matrices) is:

5 7

2 9

Matrices are frequently used in programming to represent graph data structure, in solving equations and in many other ways.

## Addition of two matrix in C

C program for matrix addition:

#include <stdio.h> int main() { int m, n, c, d, first[10][10], second[10][10], sum[10][10]; printf("Enter the number of rows and columns of matrix\n"); scanf("%d%d", &m, &n); printf("Enter the elements of first matrix\n"); for (c = 0; c < m; c++) for (d = 0; d < n; d++) scanf("%d", &first[c][d]); printf("Enter the elements of second matrix\n"); for (c = 0; c < m; c++) for (d = 0 ; d < n; d++) scanf("%d", &second[c][d]); printf("Sum of entered matrices:-\n"); for (c = 0; c < m; c++) { for (d = 0 ; d < n; d++) { sum[c][d] = first[c][d] + second[c][d]; printf("%d\t", sum[c][d]); } printf("\n"); } return 0; }

Similarly, we can create a program to subtract two matrices. You can also create a function to perform addition of two matrices.
