Extract and Modify Field in a 32-bit Register

Code

#include <stdio.h>
#include <stdint.h>

uint32_t update_register(uint32_t reg) {
    // Your logic here
    uint8_t field_value=0;
    field_value = (reg & (0x1F<<10))>>10;
    if(field_value < 31){
        field_value++;
    }
    reg &= ~(0x1F <<10);
    reg |= (field_value << 10);
    return reg;
}

int main() {
    uint32_t reg;
    scanf("%u", &reg);
    uint32_t updated = update_register(reg);
    printf("%u", updated);
    return 0;
}
