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 val = ((reg)>>10) & (0X1F);
    
    if(val < 31){
        val+=1;
        reg &= ~(0X00007C00);
        reg |= ((val & 0x1F)<<10);
    }
    return reg;
}

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