How much memory consume for integer in c?

In C, the memory consumption for an integer typically depends on the system architecture. On most platforms, a standard int takes up 4 bytes (32 bits) of memory. However, it can vary; for example, on some older or specific architectures, it might be 2 bytes (16 bits) or, in cases with larger data types, it could be 8 bytes (64 bits). The exact size can be determined using the sizeof(int) operator in C.
