Program Explanation

In this C# program, we are reading the dimension of the two matrices the number of rows and columns using ‘m’ and ‘n’ variables respectively. Using for loop enter the coefficient element values for first and second matrices respectively.

 

Using for loop, check the equality of matrices. If else condition statement is used to check that the value of A[i, j] variable is equal to value of B[i, j] variable. If the condition is true, then execute the statement and assign the value of ‘flag’ variable as true.

Otherwise, if the condition is false then execute the else statement and assign the value of ‘flag’ variable as false. Using if else condition statement print the equality of matrices.

Runtime Test Cases
 
Enter Number Of Rows And Columns Of Matrices A and B : 3  3
Enter the First Matrix : 
1 2 3
2 3 4
3 4 5
Enter the Second Matrix :
1 2 3
2 1 4
1 1 5
Matrix A :
1 2 3
2 3 4
3 4 5
Matrix B :
1 2 3
2 1 4
1 1 5
Not Equal
