Please run your code on https://ide.codingblocks.com and share the link

#3

annot convert ‘int (*)[N]’ to ‘int**’ for argument ‘1’ to ‘void displayMatrix(int**, int)’ displayMatrix(mat,N);

#4

what is meaning of this error? annot convert ‘int (*)[N]’ to ‘int**’ for argument ‘1’ to ‘void displayMatrix(int**, int)’ displayMatrix(mat,N);

#5

It means there is an issue in passing the 2-D matrix. Please make mat[N][N] a global variable, that way you won’t have to pass it to the function. Declare it with max possible size of N.

#6

please tell error https://codeshare.io/5R1oyE .please correct my code. I unable to implemet your solution

#7

I think you have shared the wrong code link

#8

https://ide.codingblocks.com/s/187672 Please take a look at this implementation
