In a program if i use /* int *a = new int [n] / (and using delete at the end), the compiler throws sigbart error but if i use / int a[n] */ it compiles successfully ,Why ?

True statement is : typename name[size of array];
It gives warning that it is forbidden in c++(11)
You can use c++(17)
If anyone knows the reason, I would also like to know. I have also faced this problem many times. Nowadays, I am using vector everywhere to prevent all array shit in c++.
If you use
new[]to allocate memory, you must usedelete[](notdelete) to free it.https://ideone.com/e.js/4vTJHE
it is still giving sigabrt or am i doing something wrong ?
There are many
out of bounderror in your code.For example, at line 10:
cin >> a[i]can crash your program wheni = n.Please remember that index in C++ is start from zero.
