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 bits_value = (reg >> 10) & 0x1F ;

    if(bits_value < 31)
    bits_value = bits_value + 1 ;

    reg = reg & ~(0x1F << 10) ; // 10-14 bits cleared

    reg = reg | (bits_value << 10) ;

    return reg;
}

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