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 = 0x1F << 10;
    uint32_t ext_field = (reg&mask) >> 10;
    if(ext_field<31)
        ext_field+=1;
    reg&=~mask;
    reg|=ext_field<<10; 
    return reg;
}

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