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 res=(0x7c00&reg)>>10;
    if(res<31){
        reg&=~(res<<10);
        res++;
        reg|=(res<<10);
    return (reg );
    }
    else
    return reg;
}

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