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 val=0;
    val = (reg & 0x7C00) >> 10;
    if(val < 31) {
        val++;
    }
    reg &= ~(31 << 10);
    reg |= (val << 10);

    return reg ;
}

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