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=((1<<5)-1)<<10;
    uint32_t value=(reg&mask)>>10;
    // printf("%d\n",31);
    if (value <31)
    {   value=(value+1)<<10;
        

        mask=~mask;
        reg=reg&mask;
        reg=reg|value;
    }
    else
        return reg;
    
    
    return reg;
}

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