Is there any way to find sum of diagonals for every submatrix in matrix by using c language.

Hi,

First you could try to use for loop to iterate every cell present in the matrix. Conditions inside the for loops ((rows < i) and (columns < j)) will ensure the program compiler, not to exceed the Matrix limit. Otherwise, the matrix will overflow. And we could use the scanf statement inside the for loop will store the user entered values in every individual array element.

In the next for loop, we could find sum of diagonal elements of a matrix.

Here is my code:

for(rows = 0; rows < i; rows++)    
{    
	for(columns = 0;columns < j;columns++)    
{  
	scanf("%d", &a[rows][columns]);    
}  
}    
      
for(rows = 0; rows < i; rows++)    
{    
	Sum = Sum + a[rows][rows];    
}    
 
printf("\n The Sum of Diagonal Elements of a Matrix =  %d", Sum );
