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 a=(reg & (0x1f << 10))>>10;
    reg =(reg & ~(0x1f << 10));
    (a < 31)? (reg=reg | (a+1)<<10 ):(reg=reg | (a)<<10);
    return reg;
}

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