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
    uint32_t mask = 0x1F<<10; 
    uint32_t field = (reg&mask)>>10;
    if (field<31) {
        field +=1; 
    }
    reg&=~mask; 
    reg|=(field<<10);
    return reg; 
}

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