Is there any dynamic allocation here new int? What is ..

Let’s say I have following definitions in C++ struct ControlReg { uint32_t reset_bit : 1; }; struct ConfigReg { uint32_t even_channel_value : 16; uint32_t odd_channel_value : 16; }; struct PeripheralRegs { volatile ControlReg control_reg; volatile uint32_t status_reg_01[2]; volatile uint32_t status_reg_02[2]; volatile ConfigReg config_reg_01[8]; volatile ConfigReg config_reg_02[8]; volatile uint32_t status_reg_03[2]; }; Can anybody tell me what ..
