Extract and Modify Field in a 32-bit Register

Code

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

uint32_t update_register(uint32_t reg) {
    int mask = 0x1F;
    uint32_t data = (reg >> 10) & 0x1F;
    // printf("%X ",data);
    if(data < 31)
    {
        reg &= 0xFFFF83FF;
        data++;
        return reg | (data << 10);
    }
    return reg ;
}

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