Develop a C program to perform addition of (3x3) matrix.

Code

// C program to add two matrices

#include<stdio.h>
int main()
{
    int r, c, mat1[100][100], mat2[100][100], sum[100][100], i, j;
    printf("\nEnter the number of rows and columns: ");
    scanf("%d %d", &r, &c);
    printf("\nInput Matrix 1 elements: ");
    for (i = 0; i < r; ++i)
        for (j = 0; j < c; ++j)
        {
            scanf("%d", &mat1[i][j]);
        }
  

    printf("\nInput Matrix 2 elements: ");
    for (i = 0; i < r; ++i)
        for (j = 0; j < c; ++j)
        {
            scanf("%d", &mat2[i][j]);
        }
   
    // Adding Two matrices
    printf("\nAdded Matrix\n");
    for (i = 0; i < r; ++i)
        for (j = 0; j < c; ++j)
        {
            sum[i][j] = mat1[i][j] + mat2[i][j];
        }

    // print the result

    for (i = 0; i < r; ++i)
        for (j = 0; j < c; ++j)
        {
            printf("%d ", sum[i][j]);

            if (j == c - 1)
            {
                printf("\n");
            }
        }

    return 0;
}
