Error statement reason

/bin/run.sh: line 4: 18 Bus error (core dumped) ./exe

when i run my code in other ide i get the right output,
but in codingblocks ide i get this error,what does this error mean?

hello @kani001 please share your code so that i can check the code .

i have foun the mistake,when i use int arr[m][n] it shows error(even though i ve got the input of m and n before this statement),but when i do with numbers eg:arr[11][11] it is working…Why is it so?The same statement arr[m][n] works in other ide except codingblocks ide…why so?

if you can share your code i can see what exactly is happening and why it is happening ?
