# Write a program to print the sum of two matrices.

Below is a program to print the sum of two matrices with step-by-step explanations.

#include <stdio.h>

int main() {

int r, c, a, b, sum, i, j;

printf(“Enter the number of rows (between 1 and 100): “);

scanf(“%d”, &r);

printf(“Enter the number of columns (between 1 and 100): “);

scanf(“%d”, &c);

printf(“\nEnter elements of 1st matrix:\n”);

for (i = 0; i < r; ++i)

for (j = 0; j < c; ++j) {

printf(“Enter element a%d%d: “, i + 1, j + 1);

scanf(“%d”, &a[i][j]);

}

printf(“Enter elements of 2nd matrix:\n”);

for (i = 0; i < r; ++i)

for (j = 0; j < c; ++j) {

printf(“Enter element b%d%d: “, i + 1, j + 1);

scanf(“%d”, &b[i][j]);

}

for (i = 0; i < r; ++i)

for (j = 0; j < c; ++j) {

sum[i][j] = a[i][j] + b[i][j];

}

// printing the result

printf(“\nSum of two matrices: \n”);

for (i = 0; i < r; ++i)

for (j = 0; j < c; ++j) {

printf(“%d   “, sum[i][j]);

if (j == c – 1) {

printf(“\n\n”);

}

}

return 0;

}

Output-

Enter the number of rows (between 1 and 100): 2

Enter the number of columns (between 1 and 100): 2

Enter elements of 1st matrix:

Enter element a11: 8

Enter element a12: 6

Enter element a21: 9

Enter element a22: 0

Enter elements of 2nd matrix:

Enter element b11: 8

Enter element b12: 8

Enter element b21: 0

Enter element b22: 9

Sum of two matrices:

16   14

9   9
