How to convert char array to int c++?

Question

C++ / C#

Hello, friends!
There is a code that converts int to char:

unsigned char a[4];
int b = 124551;

*((int *) a) = b;

Tell me, is it possible to convert a char array to int by the same principle?
Or is the only way out - element-by-element enumeration of the array?

Answer 1

unsigned char a[4] = {'1', '2', '3', '4'};
int b = *(int*)a;

Only type conversions in C++ need to be done with plus casts, not in the C style.
