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;
    uint32_t field;
    uint32_t result;

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

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