C program that calculates and displays the multiplication of two matrices.
Here is an example of a C program that calculates the multiplication of two matrices:
#include <stdio.h>
#define MAX_ROWS 10
#define MAX_COLS 10
int main() {
int A[MAX_ROWS][MAX_COLS], B[MAX_ROWS][MAX_COLS], C[MAX_ROWS][MAX_COLS];
int rowsA, colsA, rowsB, colsB;
printf("Enter number of rows and columns for matrix A: ");
scanf("%d %d", &rowsA, &colsA);
printf("Enter elements for matrix A: \n");
for (int i = 0; i < rowsA; i++) {
for (int j = 0; j < colsA; j++) {
scanf("%d", &A[i][j]);
}
}
printf("Enter number of rows and columns for matrix B: ");
scanf("%d %d", &rowsB, &colsB);
printf("Enter elements for matrix B: \n");
for (int i = 0; i < rowsB; i++) {
for (int j = 0; j < colsB; j++) {
scanf("%d", &B[i][j]);
}
}
// Check if matrices can be multiplied
if (colsA != rowsB) {
printf("Matrices cannot be multiplied.\n");
return 0;
}
// Initialize elements of matrix C to 0
for (int i = 0; i < rowsA; i++) {
for (int j = 0; j < colsB; j++) {
C[i][j] = 0;
}
}
// Perform multiplication
for (int i = 0; i < rowsA; i++) {
for (int j = 0; j < colsB; j++) {
for (int k = 0; k < colsA; k++) {
C[i][j] += A[i][k] * B[k][j];
}
}
}
printf("Result of multiplying matrices A and B: \n");
for (int i = 0; i < rowsA; i++) {
for (int j = 0; j < colsB; j++) {
printf("%d ", C[i][j]);
}
printf("\n");
}
return 0;
}
