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 val =(reg >> 10) & ((1U << 5)-1);
    if (val < 31){val ++;};
    reg &= ~(((1U<<5)-1)<<10);
    reg |= (val << 10); 
    return reg;
}

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