C Program to accept two matrices and check if they are equal or not?. Program will accept the two matrices, and return true if their order and their elements are equal, i.e. for all , if a[i][j]==b[i][j].

C Program

#include <stdio.h>

#include <stdlib.h>

void main() {

	int A[10][10], B[10][10];

	int i, j, R1, C1, R2, C2, flag =1;

	printf("Enter the order of the matrix A\n");

	scanf("%d %d", &R1, &C1);

	printf("Enter the order of the matrix B\n");

	scanf("%d %d", &R2,&C2);

	printf("Enter the elements of matrix A\n");

	for (i=0; i<R1; i++) {

		for (j=0; j<C1; j++) {

			scanf("%d",&A[i][j]);

		}

	}

	printf("Enter the elements of matrix B\n");

	for (i=0; i<R2; i++) {

		for (j=0; j<C2; j++) {

			scanf("%d",&B[i][j]);

		}

	}

	printf("MATRIX A is\n");

	for (i=0; i<R1; i++) {

		for (j=0; j<C1; j++) {

			printf("%3d",A[i][j]);

		}

		printf("\n");

	}

	printf("MATRIX B is\n");

	for (i=0; i<R2; i++) {

		for (j=0; j<C2; j++) {

			printf("%3d",B[i][j]);

		}

		printf("\n");

	}

	/* Comparing two matrices for equality */

	if(R1 == R2 && C1 == C2) {

		printf("Matrices can be compared\n");

		for (i=0; i<R1; i++) {

			for (j=0; j<C2; j++) {

				if(A[i][j] != B[i][j]) {

					flag = 0;

					break;

				}

			}

		}

	} else {

		printf(" Cannot be compared\n");

		exit(1);

	}

	if(flag == 1 )

	  printf("Two matrices are equal\n"); else

	  printf("But,two matrices are not equal\n");
