Extract and Modify Field in a 32-bit Register

Code

#include <stdio.h>
#include <stdint.h>
uint32_t update_register(uint32_t reg)
{
    uint32_t field;
    
    field = (reg>>10) & 0x1F;
    if(field<31)
    field++;
    reg &= ~(0x1f<<10);
    reg |= (field<<10);

    return reg;
}

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