26. Extract and Modify Field in a 32-bit Register

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

uint32_t update_register(uint32_t reg) {
    // Your logic here
    uint32_t field = (reg>>10) & ((1U<<5)-1);
    if( field < 31) field++;
    reg &= ~( ((1U<<5)-1) << 10 );
    reg |= (((field & (1U<<5)-1)) <<10) ;
    return reg;
}

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