141. C Program to check the given matrix is Magic matrix or not.
How does this program work?
- In this programme you will learn about how to check the given matrix is magic matrix or not.
- Matrix elements are stored in array variables.
Here is the code
#include <stdio.h>
void main()
{
int A[50][50];
int i, j, M, N;
int size;
int rowsum, columnsum, diagonalsum;
int magic = 0;
printf("Enter the order of the matrix:\n" );
scanf("%d %d", &M, &N);
if(M==N)
{
printf("Enter the elements of matrix \n" );
for(i=0; i< M; i++)
{
for(j=0; j< N; j++)
{
scanf("%d", &A[i][j] );
}
}
printf("\n\nMATRIX is\n");
for(i=0; i< M; i++)
{
for(j=0; j< N; j++)
{
printf("%3d\t", A[i][j]);
}
printf("\n");
}
// Calculate diagonal sum
diagonalsum = 0;
for(i=0; i< M; i++)
{
for(j=0; j< N; j++)
{
if(i==j)
{
diagonalsum = diagonalsum + A[i][j];
}
}
}
// Calculate row sum
for(i=0; i< M; i++)
{
rowsum = 0;
for(j=0; j< N; j++)
{
rowsum = rowsum + A[i][j];
}
if(rowsum != diagonalsum )
{
printf("\nGiven matrix is not a magic square" );
return;
}
}
// Calculate column sum
for(i=0; i< M; i++)
{
columnsum = 0;
for(j=0; j< N; j++)
{
columnsum = columnsum + A[j][i];
}
if(columnsum != diagonalsum)
{
printf("\nGiven matrix is not a magic square" );
return;
}
}
printf("\nGiven matrix is a magic square matrix" );
}
else
{
printf("\n\nPlease enter the square matrix order(m=n) \n\n");
}
}
