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[100][100], b[100][100], sum[100][100], 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]);
}
// adding two matrices
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
